The South Caspian Basin has many confirmed structures. It includes the offshore continuation of several major anticline trends extending from onshore side. The Umid Babek structure is one of the deepest structures of the Baku archipelago. It is strongly dislocated tectonically and is complicated by mud diapirism. Interpretation of 2D seismic data made it possible to determine the calculations for the area and depth in the Umid and Babek structures. The structures of Shah Deniz and Umid Babek are similar in terms of the history of their structural growth. Umid-Babek occupies the most advantageous position on the path of fluid migration from deep zones of depression and has favourable conditions for the accumulation and preservation of hydrocarbon deposits.

The results of reconnaissance studies within the Shakal and Halabja exploration blocks in Kurdistan are presented. Experimental studies were carried out using a mobile direct-prospecting technology, including modified methods of frequency-resonance processing and decoding of satellite images and photo images, vertical electric resonance scanning of the cross-section and a method of integral assessment of the oil and gas potential of large prospecting blocks and license areas. At the local survey site within the Shakal block, responses from oil, condensate, phosphorus and limestone were recorded. The lower boundary of the limestones was established at a depth of 4676 m. By scanning the cross-section from 2770 m, step 1 cm, the responses of oil from limestones were obtained from the intervals: 1) 2771-2794 m, 2) 2795.3-2815.45 m, 3) 2834.40-2854 m. During processing the image of the entire Halabja block, signals were recorded at the frequencies of oil, condensate, phosphorus gas, bacteria, sodium chloride and dolomite. At the 57 km hydrocarbon synthesis boundary, responses from oil, condensate and gas were recorded. When scanning the cross-section from 480 m to 4 km, step 50 cm, responses from oil were obtained from two intervals: 1) 1140-1200 m, and 2) 3310-3340 m. Within the local fragment of the block by scanning up to 5 km with a step of 1 m responses of oil from salt were recorded from the intervals: 1) 295-350 m, 2) 1190-1260 m, 3) 2015-2320 m). The response intervals within the 1st and 3rd horizons have been refined by scanning with a step of 5 cm. The results of experimental studies show that practical application of direct-prospecting methods and technologies will accelerate and optimize the exploration process for oil and gas.

The results of the application of mobile direct-prospecting technology of frequency-resonance processing and interpretation of satellite images and photographs at the sites of hydrogen production, drilling wells, as well as within areas of hydrogen degassing in various regions are presented. Experimental reconnaissance studies were carried out to study the features of the deep structure of the hydrogen degassing areas.
The developed mobile and low-cost technology include modified methods of satellite images and photo-images frequency-resonance processing and decoding, vertical electric-resonance scanning of a cross-section, as well as a method of integrated assessment of oil and gas potential of large prospecting blocks and license areas. Separate methods of direct-prospecting technology are based on the principles of the “substance” paradigm of geophysical research, the essence of which is searching for a specific substance - oil, gas, gas condensate, etc.
The materials of instrumental measurements indicate that in regions of basalt volcano's location with roots at different depths, signals at hydrogen frequencies are almost always recorded. When scanning the cross-section, responses from hydrogen are recorded from the upper edges of basaltic volcanoes to their roots. It can be assumed that basaltic volcanoes are a kind of channel through which hydrogen migrates to the upper horizons of the cross-section and further into the atmosphere. Within many basaltic volcanoes at a depth of 68 km, deep (living) water is synthesized. Hydrogen-rich water is curative and can be used for wellness purposes. All surveyed zones of longevity on Earth are located within basalt volcanoes, in which water synthesized at a depth of 68 km migrates to the surface and is used for water supply. Hydrogen deposits can be formed by basaltic volcanoes in adjacent sealed reservoirs. Within some survey areas, responses at hydrogen frequencies from limestones, dolomites, and marls were recorded at shallow depths. Hydrogen deposits formed near basalt volcanoes in different types of reservoirs can be discovered and localized during areal exploration using proven methods. Direct-prospecting technology can also be used to study reservoirs in crystalline rocks (basalts including). Detailed studies and wells drilling in promising areas can be planned and carried out for hydrogen and living water at the same time.
The result of the investigation indicates the advisability of using direct-prospecting methods of frequency-resonance processing of satellite images to detect zones of hydrogen accumulation in areas of basalt volcanoes location, as well as in areas of hydrogen degassing. The use of mobile and low-cost technology will significantly speed up the exploration process for hydrogen, as well as reduce the financial costs for its implementation.

Taxonomic harmonization of Paratethyan brackish ostracods described by Livent...
Neogene ostracods from Paratethys are, potentially, a powerful biostratigraphic tool to depict the geological history of different basins [Styrian, Vienna, Pannonian, Dacian, Euxinic (former extent of the modern Black Sea basin), and Caspian-Aralic basins]. Yet, most species were described by different authors (Reuss, Méhes, Zalănyi, Livental) in mid-19th and early 20th centuries and, often, descriptions and illustrations are very poor. Very likely, the Neogene Paratethyan biodiversity is overestimated due to lack of literature exchange at time or the undervaluation of ecophenotypical intra-specific variability. As a consequence, often, under different specific (or even generic) names could be hidden the same species. Unfortunately, most of the historical ostracod collection are gone lost or destroyed and the only way to solve this problem is to get new samples from the type localities.
Recently, clays and silts cropping out at Babazanan (Azerbaijan), type locality of the species described by Livental in 1929, were re-sampled, and here we present the results of our taxonomical studies of the collected ostracods providing new definition of the specific characters, mainly based on SEM illustration. An updated synonymy, paleogeographic and stratigraphic distribution starting from the extant literature, will be also provided.

Comprehensive geological, geophysical study, and exploration drilling resulted in the vast material that makes it possible to assess microfauna content of South Caspian Basin.
Commercial reservoirs have been established in the Miocene in the South Caspian Basin. The Miocene deposits in South Caspian Basin are of great practical and scientific interest as they underlie the formations of the thick Pliocene Productive series. The core samples taken from exploration wells of the Miocene deposits, where were recovered otholitite, abundant ostracod and foraminifera fauna. The studied sections allowed to define the detailed stratigraphy sequences into individual stratigraphic units: Pontian, Sarmatian, Conkian-Karaganian, Chokrakian, Maikopian deposits
The facies of the Miocene deposits in the South Caspian offshore part of Basin vary considerably and these different facial sedimentary environments affected the microfauna composition as well. This is confirmed by rather abrupt changes in microfauna features from different regions of South Caspian Basin. The Miocene deposits of South Caspian offshore part of basin is rich in microfauna and many of ostracod species here were common in the Tethys and Paratethys bioprovince and is known as brackish and shallow marine genus in the ecology of ostracod assemblages

Results of reconnaissance survey _Profile TESZ-2021_FINAL_short version.pdf
The results of a reconnaissance survey of a seismic profile on Ukraine territory are presented. Experimental studies were carried out with the aim of additional approbation of direct-prospecting methods and improvement of methodological techniques of their application in the exploration process for oil, gas and natural hydrogen, as well as in the study of the deep structural elements of the Earth. The results indicate that it is promising for the detection of HC deposits in the cross-section and the expediency of carrying out prospecting works of a detailed nature within it. In the northern part of the research area, by instrumental measurements a basalt volcanic complex has been localized, which is promising for of natural hydrogen and living water accumulations searching in the cross-section. During the cross-section scanning, responses at gas frequencies were recorded without interruption up to 5 km, which may indicate the presence of a deep channel within the surveyed area, through which oil, condensate and gas migrate to the upper horizons of the cross-section. The results of the survey indicate the advisability of direct-prospecting methods and technologies using when studying the deep structure of small areas and large blocks by geoelectric and seismic methods.

Within the framework of a new, "substance" (“matter”) paradigm of geophysical research, a "direct" search for a specific physical substance is carried out: gas, oil, gas hydrates, water, ore minerals and rocks (gold, platinum, silver, zinc, uranium, diamonds, kimberlites, etc.). The initial stage in the development of this paradigm can be considered the first research and development on the "direct" methods for oil and gas searching.

A.j.on ecology issue of south caspian lankaran–talish–deniz and khazar areas
Thus, the analysis of the borehole data, seismic data, and biostratigraphy confirmed that the Tertiary sediments consist of fluvial- deltaic–lacustrine sediments deposited in the isolated South Caspian Basin, particularly in the study area by several river systems.
The study area has several characteristics typical of landlocked marine environments: Low salinity; low HD conditions, causing stratification of the water column. High primary productivity of the water mass, generating conditions of dissolved oxygen supersaturation and deficits (of phosphorus and probably of oxygen at night). Also at the sediment level, the heterogeneity of the substrate and low benthic fauna content is typical of confined habitats, in which environmental conditions are especially difficult for the higher organisms.
The micro-pollutant concentration in both the water and sediment, a point also common to most confined habitats and related to the inflow from the catchment area. It is related to the fine fraction of the sediment and may be masked by the presence of numerous shell debris which “dilute” the muds and thereby the micro-pollutants and organic matter, usually settled on these fine sediment fractions. All the observations made on the study, substantial primary production, a paucity of benthos, etc are consistent with those made by different authors describing the Caspian Sea. The study area has high quantities of contaminants and low capabilities for dispersing potential intake, but on the other hand, has a distinct resistance to the influence of any future impediments
Geological & Prospective peculiarity of Kapaz field on South Caspian basin,
Kapaz field is located in the central part of the Apsheron-Pribalkhan threshold between the Azeri and Livano structures- in the west of the Caspian sea. Water depth changes from 90 m in the east to 130 m in the west, in the area. In the seismic cross-sections of the Kapaz field, deposits from Quaternary to Miocene are observed, the cross-sections were revised using the Ostracoda and Formaninifera fauna contents based on regional well correlations. The tectonic structures are an asymmetric anticline striking NW-SE. The folding undulated the upper Pliocene twice and the middle Pliocene thrice. Secondary undulations present as dome-shaped uplifts (3-5 1.5-2,0 km). The size on the fold in the base of the upper division of the middle Pliocene is 25 x2.5 km. The structure in the base of the upper division of the Middle Pliocene is displaced relative to the structure of the top of the mIddle Pliocene to the northwest along the fol axis 3.5-4 km. Oil and gas potential in the southwestern and northeastern slopes of the structure is associated with the deposits from the suite of Pereriva and also with the underlying suits of PS. Concerning Kapaz field evaluation, it is recommended to drill wells to strip up to the KaS as it was done in the Turkmenistan sector of the Caspian Sea in the Livanova, Gubkina, and Lam field. Taking into account the anomalous high-pressure layer below the suite of Pereriva every effort should be taken to strip up to the KaS successfully
To the geology of tertiary quaternary sediments of south-west part of the ...
The SW part of south Caspian offshore studied very poorly. Data studied from numerous offshore shallow engineering and deep exploration wells have provided useful information on the geology of the Tertiary- Quaternary sediments. The log, seismic data, and biostratigraphy confirmed that the Tertiary sediments consist of fluvial- deltaic–lacustrine sediments deposited in the isolated South Caspian Basin, particularly in the study area by several river systems. A Quarternary period is characterized by brackish water sediments. The "short" series of marine sediments of the deep and shallow facies of open sea bays, delta, and marine shallow waters are typical for the SW part of the Caspian.
Pliocene and Quaternary sediments unconformably overlie more ancient formations, until the Mesozoic sediments are located at a relatively shallow depth. In the Lankaran-Talysh Deniz, the Miocene sequences below the middle part of Pliocene Pereryva formation are pinching out against the basin margin. The thickness of these series increases stepwise across the main structures giving evidence of a rift-system developing at the beginning of major subsidence in the South Caspian during the early Tertiary. No hydrocarbon discovery except little oil and gas shows are found in SW of the Caspian due to several geological reasons such as a reservoir, vertical and lateral migration problem.
2d poster about coring procedure
1. Conventional coring involves pulling the drill string out of the hole, attaching a core barrel assembly, and running it back into the hole to retrieve core samples.
2. The core barrel assembly consists of an inner and outer tube. Mud circulation is used before and during coring to clean the inner tube and divert flow to the annulus to prevent damaging the core sample.
3. To start coring, the drill string is pulled, the coring head is attached and run back into the hole, then mud is circulated and a ball is dropped to start cutting cores which enter the inner tube for retrieval.
1st poster example of core analysis program
The document outlines the key steps for designing and managing an effective core analysis program, including appointing a program focal point, reviewing existing core data, designing the testing program with laboratory assistance, selecting a laboratory contractor, and preparing final reports. It also provides examples of specialized core analysis programs for different reservoir lithologies and examples of recommended routine and special core analysis tests for gas and oil reservoirs.
Days 3d porosity , permeability, fluid saturation
Porosity is a key property of reservoir rocks that represents the pore volume as a fraction of bulk volume. It can be measured through laboratory analysis of rock samples or estimated from well logs. Several factors influence porosity, including grain size, sorting, cementation, and compaction. Common techniques to determine porosity include measuring pore volume directly through fluid extraction or injection methods, or calculating it by finding the grain volume and subtracting it from bulk volume. Understanding porosity distribution is important for reservoir characterization and fluid flow modeling.

Presentation mpog meor new
his paper presents the Microbial Prospection for Oil and Gas (MPOG) method, which uses microbiological techniques to explore for oil and gas. These techniques are based on the principle that light hydrocarbons from oil and gas fields escape to the earth’s surface, and this increased hydrocarbon supply above the fields creates conditions favorable for the development of highly specialized bacterial populations that feed on the hydrocarbons. This leads to significant increases in the microbial cell numbers and cell activity of these specialized microbes. By developing methods to establish the separate activities of methane-oxidizing bacteria (a gas indicator) and those bacteria that oxidize only ethane and higher hydrocarbons (oil indicators), it is possible to differentiate between oil fields with and without a free gas cap, and gas fields.In unexplored areas, MPOG represents a cost-effective method for preliminary exploration work. In mature areas, the method is helpful for ranking seismically defined geologic structures by indicating possible infill locations, as a contribution to reservoir characterization. No geologic or seismic data are required to carry out microbial prospection. In areas that have not yet been investigated geophysically, this technique can be applied as wildcat prospection. The sampling points are laid over the surface to be investigated, in the form of a map grid. The biochemical activity of the HCO represents the cumulative parameters. These are calculated by
• quantifying the consumption of added hydrocarbons (methane and/or propane and butane) using gas chromatography and pressure measurements • determining the biological CO2 formation rate
Microbial enhanced oil recovery (MEOR) represents the use of microorganisms
to extract the remaining oil from reservoirs. This technique has the potential
to be cost-efficient in the extraction of oil remained trapped in capillary pores of
the formation rock or in areas not swept by the classical or modern enhanced oil
recovery (EOR) methods, such as combustion, steams, miscible displacement, caustic
surfactant-polymers flooding, etc. Thus, MEOR was developed as an alternative
method for the secondary and tertiary extraction of oil from reservoirs,
The Quaternary deposits of the South Caspian and the adjacent areas on ostrac...
The South Caspian is one of the largest oil-producing regions within the Caspian Sea. Most of the offshore fields are focused here along with the main geologic oil and gas reserves of Azerbaijan. The development of the discovered fields, prospects and exploration of new ones require detailed study of the Quaternary deposits: their material composition, stratigraphy, thicknesses and other properties. It is necessary to study these issues not only for improvement of the efficiency, provide safe geological prospecting and exploration, but also to solve engineering and geological tasks related to the planned development of discovered oil and gas fields.
Study of fauna and stratigraphy of the Quaternary deposits in the South Caspian is important to learn the Quaternary history of the Caspian Sea. The Quaternary time is known for its frequent and abrupt fluctuations in climate, ocean and sea levels, considerable changes in topography, fauna, flora and other natural components of the Earth. The large-scale well drilling in the South Caspian water area provided geological information particularly about ostracod fauna, stratigraphy and litho-facies features of the Quaternary deposits of the studied regions.
We investigated the systematic composition and distribution regularities of ostracod fauna from the Quaternary deposits over the vast South Caspian territory, including the stratigraphic role of the fauna and correlation of the data with the coastal –onshore area. Multiple well sections and their enclosed micro- and macro fauna were the study target. When we analyzed and correlated well sections and natural outcrops we used other methods like lithological, macro fauna, radiometric, electric logging, seismic logging as well. The result of our study allowed us to design a detailed stratigraphic chart for the Quaternary deposits of the entire South Caspian basin. For the first time the Quaternary deposits of the South Caspian breakdown with 5 supra horizons, 10 horizons with 7 index species. Index species were identified on the successive change of zonal complexes- biozones. All these subdivisions play a regional role and correlated well with the ones from the adjacent areas of the Caspian region.
The paleontological processing of individual ostracod of genera: Leptocythere, Amniocythere, Euxinocythere, others allowed us to identify specific features among them in order to differentiate a new ostracod species.
We also highlighted the issues of stratigraphy, facies analysis and thicknesses of the Quaternary deposits in the South Caspian. The analysis of facies, thicknesses and fauna distribution shows that in the Quaternary time the South Caspian region was characterized by rather dynamic paleogeographic settings: along with the active change of the sea bottom topography, salinity and temperature varied considerably and often, as well as the sea level.
Geological &prospective peculiarity of Kapaz field on S.Caspian part 29 36
This presentation published in international Earth Sciences Colloquium of the Aegean Regions, in Izmir, Turkey in 2005. The Apsheron trend characterised by large, east to west striking folds and structures of the Pliocene section overlying and burying the underlying rifted margin structures and half-grabens of the Cretaceous, Jurassic and possibly Triassic continental margin and shelf. The Tertiary structures display strike-slip influence, such as reversal of normal faults that bound the underlying half grabens; local back thrusting and flower-like structuring are common. The most significant volumetric potential lies in the offshore. Three elements are key to the extraordinary oil and gas potential of the South Caspian Basin. The high-quality reservoir sands are the Volga Pliocene delta and a lesser extent.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

Results of reconnaissance survey _Profile TESZ-2021_FINAL_short version.pdf
The results of a reconnaissance survey of a seismic profile on Ukraine territory are presented. Experimental studies were carried out with the aim of additional approbation of direct-prospecting methods and improvement of methodological techniques of their application in the exploration process for oil, gas and natural hydrogen, as well as in the study of the deep structural elements of the Earth. The results indicate that it is promising for the detection of HC deposits in the cross-section and the expediency of carrying out prospecting works of a detailed nature within it. In the northern part of the research area, by instrumental measurements a basalt volcanic complex has been localized, which is promising for of natural hydrogen and living water accumulations searching in the cross-section. During the cross-section scanning, responses at gas frequencies were recorded without interruption up to 5 km, which may indicate the presence of a deep channel within the surveyed area, through which oil, condensate and gas migrate to the upper horizons of the cross-section. The results of the survey indicate the advisability of direct-prospecting methods and technologies using when studying the deep structure of small areas and large blocks by geoelectric and seismic methods.
Direct-prospecting methods_Presentation.ppt
Within the framework of a new, "substance" (“matter”) paradigm of geophysical research, a "direct" search for a specific physical substance is carried out: gas, oil, gas hydrates, water, ore minerals and rocks (gold, platinum, silver, zinc, uranium, diamonds, kimberlites, etc.). The initial stage in the development of this paradigm can be considered the first research and development on the "direct" methods for oil and gas searching.

A.j.on ecology issue of south caspian lankaran–talish–deniz and khazar areas
Thus, the analysis of the borehole data, seismic data, and biostratigraphy confirmed that the Tertiary sediments consist of fluvial- deltaic–lacustrine sediments deposited in the isolated South Caspian Basin, particularly in the study area by several river systems.
The study area has several characteristics typical of landlocked marine environments: Low salinity; low HD conditions, causing stratification of the water column. High primary productivity of the water mass, generating conditions of dissolved oxygen supersaturation and deficits (of phosphorus and probably of oxygen at night). Also at the sediment level, the heterogeneity of the substrate and low benthic fauna content is typical of confined habitats, in which environmental conditions are especially difficult for the higher organisms.
The micro-pollutant concentration in both the water and sediment, a point also common to most confined habitats and related to the inflow from the catchment area. It is related to the fine fraction of the sediment and may be masked by the presence of numerous shell debris which “dilute” the muds and thereby the micro-pollutants and organic matter, usually settled on these fine sediment fractions. All the observations made on the study, substantial primary production, a paucity of benthos, etc are consistent with those made by different authors describing the Caspian Sea. The study area has high quantities of contaminants and low capabilities for dispersing potential intake, but on the other hand, has a distinct resistance to the influence of any future impediments
Geological & Prospective peculiarity of Kapaz field on South Caspian basin,
Kapaz field is located in the central part of the Apsheron-Pribalkhan threshold between the Azeri and Livano structures- in the west of the Caspian sea. Water depth changes from 90 m in the east to 130 m in the west, in the area. In the seismic cross-sections of the Kapaz field, deposits from Quaternary to Miocene are observed, the cross-sections were revised using the Ostracoda and Formaninifera fauna contents based on regional well correlations. The tectonic structures are an asymmetric anticline striking NW-SE. The folding undulated the upper Pliocene twice and the middle Pliocene thrice. Secondary undulations present as dome-shaped uplifts (3-5 1.5-2,0 km). The size on the fold in the base of the upper division of the middle Pliocene is 25 x2.5 km. The structure in the base of the upper division of the Middle Pliocene is displaced relative to the structure of the top of the mIddle Pliocene to the northwest along the fol axis 3.5-4 km. Oil and gas potential in the southwestern and northeastern slopes of the structure is associated with the deposits from the suite of Pereriva and also with the underlying suits of PS. Concerning Kapaz field evaluation, it is recommended to drill wells to strip up to the KaS as it was done in the Turkmenistan sector of the Caspian Sea in the Livanova, Gubkina, and Lam field. Taking into account the anomalous high-pressure layer below the suite of Pereriva every effort should be taken to strip up to the KaS successfully
To the geology of tertiary quaternary sediments of south-west part of the ...
The SW part of south Caspian offshore studied very poorly. Data studied from numerous offshore shallow engineering and deep exploration wells have provided useful information on the geology of the Tertiary- Quaternary sediments. The log, seismic data, and biostratigraphy confirmed that the Tertiary sediments consist of fluvial- deltaic–lacustrine sediments deposited in the isolated South Caspian Basin, particularly in the study area by several river systems. A Quarternary period is characterized by brackish water sediments. The "short" series of marine sediments of the deep and shallow facies of open sea bays, delta, and marine shallow waters are typical for the SW part of the Caspian.
Pliocene and Quaternary sediments unconformably overlie more ancient formations, until the Mesozoic sediments are located at a relatively shallow depth. In the Lankaran-Talysh Deniz, the Miocene sequences below the middle part of Pliocene Pereryva formation are pinching out against the basin margin. The thickness of these series increases stepwise across the main structures giving evidence of a rift-system developing at the beginning of major subsidence in the South Caspian during the early Tertiary. No hydrocarbon discovery except little oil and gas shows are found in SW of the Caspian due to several geological reasons such as a reservoir, vertical and lateral migration problem.
2d poster about coring procedure
1. Conventional coring involves pulling the drill string out of the hole, attaching a core barrel assembly, and running it back into the hole to retrieve core samples.
2. The core barrel assembly consists of an inner and outer tube. Mud circulation is used before and during coring to clean the inner tube and divert flow to the annulus to prevent damaging the core sample.
3. To start coring, the drill string is pulled, the coring head is attached and run back into the hole, then mud is circulated and a ball is dropped to start cutting cores which enter the inner tube for retrieval.

Days 3d porosity , permeability, fluid saturation
Porosity is a key property of reservoir rocks that represents the pore volume as a fraction of bulk volume. It can be measured through laboratory analysis of rock samples or estimated from well logs. Several factors influence porosity, including grain size, sorting, cementation, and compaction. Common techniques to determine porosity include measuring pore volume directly through fluid extraction or injection methods, or calculating it by finding the grain volume and subtracting it from bulk volume. Understanding porosity distribution is important for reservoir characterization and fluid flow modeling.

Presentation mpog meor new
his paper presents the Microbial Prospection for Oil and Gas (MPOG) method, which uses microbiological techniques to explore for oil and gas. These techniques are based on the principle that light hydrocarbons from oil and gas fields escape to the earth’s surface, and this increased hydrocarbon supply above the fields creates conditions favorable for the development of highly specialized bacterial populations that feed on the hydrocarbons. This leads to significant increases in the microbial cell numbers and cell activity of these specialized microbes. By developing methods to establish the separate activities of methane-oxidizing bacteria (a gas indicator) and those bacteria that oxidize only ethane and higher hydrocarbons (oil indicators), it is possible to differentiate between oil fields with and without a free gas cap, and gas fields.In unexplored areas, MPOG represents a cost-effective method for preliminary exploration work. In mature areas, the method is helpful for ranking seismically defined geologic structures by indicating possible infill locations, as a contribution to reservoir characterization. No geologic or seismic data are required to carry out microbial prospection. In areas that have not yet been investigated geophysically, this technique can be applied as wildcat prospection. The sampling points are laid over the surface to be investigated, in the form of a map grid. The biochemical activity of the HCO represents the cumulative parameters. These are calculated by
• quantifying the consumption of added hydrocarbons (methane and/or propane and butane) using gas chromatography and pressure measurements • determining the biological CO2 formation rate
Microbial enhanced oil recovery (MEOR) represents the use of microorganisms
to extract the remaining oil from reservoirs. This technique has the potential
to be cost-efficient in the extraction of oil remained trapped in capillary pores of
the formation rock or in areas not swept by the classical or modern enhanced oil
recovery (EOR) methods, such as combustion, steams, miscible displacement, caustic
surfactant-polymers flooding, etc. Thus, MEOR was developed as an alternative
method for the secondary and tertiary extraction of oil from reservoirs,
The Quaternary deposits of the South Caspian and the adjacent areas on ostrac...
The South Caspian is one of the largest oil-producing regions within the Caspian Sea. Most of the offshore fields are focused here along with the main geologic oil and gas reserves of Azerbaijan. The development of the discovered fields, prospects and exploration of new ones require detailed study of the Quaternary deposits: their material composition, stratigraphy, thicknesses and other properties. It is necessary to study these issues not only for improvement of the efficiency, provide safe geological prospecting and exploration, but also to solve engineering and geological tasks related to the planned development of discovered oil and gas fields.
Study of fauna and stratigraphy of the Quaternary deposits in the South Caspian is important to learn the Quaternary history of the Caspian Sea. The Quaternary time is known for its frequent and abrupt fluctuations in climate, ocean and sea levels, considerable changes in topography, fauna, flora and other natural components of the Earth. The large-scale well drilling in the South Caspian water area provided geological information particularly about ostracod fauna, stratigraphy and litho-facies features of the Quaternary deposits of the studied regions.
We investigated the systematic composition and distribution regularities of ostracod fauna from the Quaternary deposits over the vast South Caspian territory, including the stratigraphic role of the fauna and correlation of the data with the coastal –onshore area. Multiple well sections and their enclosed micro- and macro fauna were the study target. When we analyzed and correlated well sections and natural outcrops we used other methods like lithological, macro fauna, radiometric, electric logging, seismic logging as well. The result of our study allowed us to design a detailed stratigraphic chart for the Quaternary deposits of the entire South Caspian basin. For the first time the Quaternary deposits of the South Caspian breakdown with 5 supra horizons, 10 horizons with 7 index species. Index species were identified on the successive change of zonal complexes- biozones. All these subdivisions play a regional role and correlated well with the ones from the adjacent areas of the Caspian region.
The paleontological processing of individual ostracod of genera: Leptocythere, Amniocythere, Euxinocythere, others allowed us to identify specific features among them in order to differentiate a new ostracod species.
We also highlighted the issues of stratigraphy, facies analysis and thicknesses of the Quaternary deposits in the South Caspian. The analysis of facies, thicknesses and fauna distribution shows that in the Quaternary time the South Caspian region was characterized by rather dynamic paleogeographic settings: along with the active change of the sea bottom topography, salinity and temperature varied considerably and often, as well as the sea level.

This presentation published in international Earth Sciences Colloquium of the Aegean Regions, in Izmir, Turkey in 2005. The Apsheron trend characterised by large, east to west striking folds and structures of the Pliocene section overlying and burying the underlying rifted margin structures and half-grabens of the Cretaceous, Jurassic and possibly Triassic continental margin and shelf. The Tertiary structures display strike-slip influence, such as reversal of normal faults that bound the underlying half grabens; local back thrusting and flower-like structuring are common. The most significant volumetric potential lies in the offshore. Three elements are key to the extraordinary oil and gas potential of the South Caspian Basin. The high-quality reservoir sands are the Volga Pliocene delta and a lesser extent.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
