Delineation of Hydrocarbon Bearing Reservoirs from Surface Seismic and Well L...IOSR Journals
Hydrocarbon reservoir has been delineated and their boundaries mapped using direct indicators from 3-D seismic and well log data from an oil field in Nembe creek, Niger Delta region. Well log signatures were employed to identify hydrocarbon bearing sands. Well to seismic correlation revealed that these reservoirs tied with direct hydrocarbon indicators on the seismic section. The results of the interpreted well logs revealed that the hydrocarbon interval in the area occurs between 6450ft to 6533ft for well A, 6449ft to 6537ft for well B and 6629ft to 6704ft for well C; which were delineated using the resistivity, water saturation and gamma ray logs. Cross plot analysis was carried out to validate the sensitivity of the rock attributes to reservoir saturation condition. Analysis of the extracted seismic attribute slices revealed HD5000 as hydrocarbon bearing reservoir.
Artificial Recharge to Alluvial Aquifer, Northeastern Nuba Mountains, Sudan.IJRES Journal
Many engineering geology and structural geology aspects have been used in this study, to point out the suitability of the site for artificial recharge to alluvial aquifer, such as; rocks and soil types, seepage rate, structures and lineaments. The area is under lied by basement rocks with considerable thickness (10 to 15 m) of alluvial deposit. Overall soil type is sandy soil and its seepage rate is 34.56 Liter per hour. The most existing lineaments are trending toward NW direction while rocks foliation dipping toward WWN direction. The site is satisfied to be artificial recharge.

Morphometry and Hydrology relationship in Lidder valleyShakil Romshoo
Morphometric analysis of the Lidder catchment was carried out using geospatial technique.The analysis revealed that the area has uniform lithology and is structurally permeable. The high drainage density of all
subwatersheds indicate more surface runoff.The morphometric analysis also indicates that the area is more prone to weathering due to very-coarse to coarse drainage texture.
Mineral potential mapping as a strategic planning tool in the eastern Lachlan...Kenex Ltd
The Geological Survey of New South Wales (GSNSW) is undertaking a statewide mineral potential mapping project driven by the need to provide justifiable land use planning advice to key government stakeholders and to highlight the exploration potential of the state’s major mineral systems at a regional scale. Following delivery of mineral potential data packages for the Southern New England Orogen in 2017, and the Curnamona Province and Delamerian Thomson Orogen in 2018, the eastern Lachlan Orogen was selected as the next area for a review of key mineral systems and mineral potential. The study area covers the Lachlan Orogen east of the Gilmore Fault and the study mapped the mineral potential for porphyry Cu–Au, polymetallic skarn, Kanimblan orogenic Au, Tabberabberan orogenic Au, and VAMS mineral systems.

Mineral potential mapping in Bundarra, QueenslandKenex Ltd
The Bundarra porphyry Cu-Au project is held by Duke Exploration Ltd, and is located in central Queensland, Australia, 110 km south-west of Mackay. The project was acquired in 2017. Kenex has completed, for Duke, detailed mineral potential mapping over the project area, in order to focus drilling funds on the most prospective areas.
The project area surrounds the Cretaceous Bundarra Granodiorite, which intrudes the Permian Back Creek Group carbonaceous shales, sandstones and marls. Numerous Cu-Au occurrences are present within or near the hornfelsed contact aureole of the granodiorite. The project has been subject to significant exploration work, including mining of high-grade ore shoots in the late 1800s to early 1900s, however, modern exploration has been sporadic, and without comprehensive follow-up of encouraging results.
All available historic data has been compiled and incorporated into a mineral potential map based on the porphyry mineral system. Maps representing all components of the porphyry mineral system including source, transport, trap and deposition have been created, resulting in binary maps which show where each characteristic is present or absent. These are then compared to known mineral occurrences, or training points. The weights of evidence technique was used for the modelling. This technique calculates the relationship of the area covered by the characteristic being tested and the number of training data points that fall within that area. For each map a contrast value ‘C’ gives a relative measure of the strength of the correlation, and a Studentised contrast value ‘StudC’ gives a relative measure of the reliability of the C value, i.e. a high C and StudC value implies a strong spatial correlation and a reliable result, which occurs when more training points are captured within a smaller area.
The maps with the best spatial correlation to the training points for each mineral system component were selected for the final mineral potential model. Table 1 shows the eight spatial variables which were selected from a total of 60 mapped.

Effects of shale volume distribution on the elastic properties of reserviors ...DR. RICHMOND IDEOZU
Shale volume (Vsh) estimation has been carried out on three selected reservoirs (Nan.1, Nan.2, and Nan.4) distributed across four wells (01, 03, 06, and 12) in Nantin Field, using petrophysical analysis and reservoir modeling techniques with a view to understanding the reservoir elastic properties. Materials utilized for this research work include: Well Log data (Gamma Ray Log, Resistivity Log, Sonic Log, Density Log, Neutron porosity log), and a 3-D Seismic volume were used for the study. Sand and shale were the prevalent lithologies in Nantin Field. Nan. 1 reservoir was thickest in Nantin well 12 (29.7ft), Nantin 2 reservoir was thickest in Nantin Well 12 (30.9ft) while Nantin 4 reservoir was thickest in Well 3 (72ft). Correlation well panel across the Field showed that Nantin 4 reservoir, was thicker than Nan 1 and Nan 2 Reservoir respectively. Normal and synthetic Faults were also mapped, the trapping system in the field includes anticlines in association with fault closures. The thicknesses and lateral extents of these reservoirs were delineated into three zones (1, 2, and 3) which were modeled appropriately. Petrophysical and some elasticity parameters such as Poisson ratio (PR), Acoustic Impedance (AI), and Reflectivity Coefficient (RC) were evaluated for the wells. The results from elasticity evaluation showed a high Poisson Ratio of 0.40 in Nantin 2 reservoir of Well 12 based on high shale volume distribution of 0.70 indicating high stress level and possible boundary to hydraulic fracture. The lowest Poisson Ratio was evaluated in Nantin reservoir of Well 1 with lowest shale volume of 0.18 which indicates weak zones and may not constrain a fracturing job. Results from Acoustic impedance showed a high AI value of 7994.3 in Nan 2 Reservoir compared to Nan.1 which has the least AI value of 7447.3 because of low shale volume. A higher Reflectivity Coefficient of 0.01 was recorded in Nan.2 reservoir indicating bright spot while a lower RC of -0.00023 was recorded in Nan.4 Reservoir indicating dim spot. Hydrocarbon volume estimate of the three reservoirs showed 163mmstb in Nan.1 reservoir, 169mmstb, in Nantin 2 reservoir and 115mmstb in Nan. 4 Reservoir. The reservoirs encountered were faulted and laterally extensive. Nantin 2 reservoir was more prolific with a STOIIP of 169 mmstb compared to Nan. 1 with a STOIP of 163 mmstb and Nantin.4 with a STOIP of 115 mmstb, because of its good petrophysical values, facies quality and low shale volume distributions.
Statistical Tuning Chart for Mapping Porosity Thickness: a Case Study of Chan...TELKOMNIKA JOURNAL
Reservoir assessment is not only controlled by the structural framework but also stratigraphical
features. Stratigraphical interpretation, which is related to seismic amplitude interpretation, is used to
describe petrophysical aspects of channel sand reservoirs such as net porosity and thickness. This paper
aims to map the porosity thickness for a case study of channel sand bodies reservoir in the Kutei basin.
The study area is complex channel reservoir system that appears to occupy specific area within the
depositional system. The geometry of the sediment channel, which thins toward the channel margins,
makes this feature similar to be wedge model that could possibly be influenced by tuning effects. The
tuning effects introduce pitfall in interpreting high-quality reservoir that is affected by contrasts in acoustic
impedance. In order to distinguish high amplitude responses caused by tuning effects and acoustic
properties, the analysis of amplitude responses needs to be correlated to the reservoir thickness. The
statistical tuning chart is one of the techniques used to correlate amplitude responses and the reservoir
thickness. The application of this technique to real data sets shows net porosity thickness map over the
targeted reservoir. Thus, high-quality reservoir characterization can be performed to delineate geometric
framework of the reservoir.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

area 450.0km2 dimensional work area, this research work is mainly for the British Ministry of the well region
86 Heidimiao Sec deploy assessing control wells, the purpose is through the block of seismic geological
research, evaluation of horizontal wells and infrastructure development, the focus on "dessert reservoir"
prediction method to obtain a high sandstone and oil drilling rate and enhance individual well production.
III. RESERVOIR " DESSERT " RESERVOIR PREDICTION
Horizontal wells will focus on aspects of the deployment of a "sweet spot" reservoir prediction,
horizontal wells in reservoir development only deployed position, in order to obtain a high sandstone and oil
drilling rate and enhance individual well production.
3.1 seismic attribute analysis
Based on lithology, electrical characteristics were carried out against Heidimiao for HII2 oil group
attribute analysis, the corresponding strata were studied slice properties, phase shift processing data volume,
relative wave impedance characteristics, micro seismic facies waveform clustering qualitative group of Black
HII2 favorable reservoir sand body position.
3.1.1 Heidimiao strata slice attribute analysis
Seismic data commonly used technologies include horizontal slice slice, slice along the layer formation
information reflected in two different sections. Also known as time slicing slice level, it reflects the same
geological characteristics of the ground time domain isochronous surface, can show abnormal seismic attribute

spatial distribution, determine the direction of extension of the deposition system, which applies to sheeted and
supine formation, so as to The seismic attributes and other information with the horizontal plane parallel to the
deposition system contains extracted. Horizon slice refers to the purpose of the layers along the surface of the
slice, known as seismic sections along the floor, it is not only adapt, but not prostrate mat-like formation, but
also to adapt to fluctuating formations, especially to reflect more accurately inclined strata geological
characteristics and changes of sedimentary reservoirs. Slicing through the layer can show the ups and downs
along the inclined anomalies and seismic attribute spatial distribution, determine the direction of extension of
the deposition system, it is for the inclined plane parallel to the depositional system in order to ensure that when
the extracted seismic attribute information, etc., for the inclined plane not parallel deposition system, his
presence in the layer time slicing through the phenomenon of change information within the sedimentary system
under seismic attribute information extraction and other frameworks do not reflect lithology.
3.1.2 Phase shift process
Bandwidth seismic waves directly affects the level of resolution, to ensure no loss of low-frequency
component of the premise, the resolution was a positive relationship with the bandwidth, zero-phase wavelet
highest resolution. Seismic data processing seismic wavelet is often assumed that the minimum phase wavelet,
minimum phase asymmetric waveform, and the sub-Bourbon lobe longer, can not simply take advantage of the
peaks and layer interface or correspondence between the layers. Therefore, before seismic interpretation, to be
converted into a minimum-phase wavelet zero-phase wavelets. For thin, especially thin interbedded geologic
conditions, even if they can obtain a zero phase wavelet, still have to face the top of the formation, the end of the
interface question reflection indistinguishable, so to improve the thin, thin interbedded interpretation accuracy,
but alsoWe must rely on well constrained geological knowledge and data. In general, the results of seismic data
processing phase existing data volume is essentially zero phase is not, therefore, in practice, the need to
determine the polarity and phase angle seismic data, seismic data, based on the original by turning the
corresponding phase angle, so that the purpose of the seismic data interval phase angle approaching 90 °, more
suitable for the direct application of thin reservoir prediction of seismic information.
3.2 Seismic inversion
3.2.1 Sandstone quantitative prediction method
Sandstone quantitative forecasting methods currently used in the well - seismic impedance inversion
based, multi-well constrained inversion to logging data-rich high-frequency information and a complete
complement to the low-frequency components of seismic limited bandwidth, access high-resolution formation
impedance and various logs Association simulation data volume. It provides initial exploration into the
development phase of the corresponding inversion method: recursive inversion, constrained sparse pulse
inversion, stochastic simulation and stochastic seismic inversion and reservoir characteristics of the integrated
inversion. Wherein the geostatistical inversion using seismic data, logging data, and establish a high-resolution
geological modeling or pattern matching to get the main component of the reservoir model, is a model-based
inversion method, focusing on the thin and fine prediction reservoir description. The principle is: seismic data
volume for each channel can be represented in a linear combination of a few of its neighbor, which reflects the
relationship between the coefficient matrix of this linear combination, reflects the subsurface variation from one
point to another point. And this law is unique, it will be applied to log data body, get well logging constrained
seismic inversion. Closely integrated with the seismic data, the two mutual restraint, in time, establish the
correct time-depth relationships through sonic depth of field on the curve, and thus the entire seismic data for
various logging curve.
3.2.2 Forecasting process and quality control
First, a variety of data loading, including seismic data, interpret the data, well log, hierarchical data,
etc., and various well region of the curve, each year, different instruments obtained was normalized; secondly
extracting wavelet, making synthetic records, repeatedly adjust wavelets, so that the resulting synthetic
seismogram and seismic traces the well reaches the maximum correlation, thus establishing the initial model.
Then inversion according to the model, the study area Heidimiao HⅡ2 small layer of sand low GR, significantly
high resistance characteristics, based on geostatistical impedance inversion on feature GR and resistivity curve
random co-simulation, multiple attribute comprehensive prediction sand body distribution; Finally, based on the
inversion data volume, by logging data analysis to determine the purpose of sand and shale layer threshold
values and calculation purposes sandstone thickness and effective thickness, and finally the plane of FIG.

3.3 Geostatistical Inversion
Geostatistical method steps are as follows: 1) analysis of the variogram data; 2) find the relationship
between seismic and log data to find the variation between the correlation analysis; 3) the use of the known data
analysis to determine the law to get the space distribution of the control points. Commonly used tool is the
Kriging method.
Picture 1 petrophysical analysis
From geological point of view, the Spatial characteristics of the reservoir space geometry, material
properties and other parameters are in effect under the law of a series of geological origin of the formation.
Picture 1 is a well region 86 British Heidimiao impedance curve and lithology analysis histogram intersection of
gamma ray and resistivity analysis diagram, of which only divided the sandstone and mudstone are two, we can
see that the impedance curve of sand and shale It has some ability to distinguish between the impedance value of
less than 6800 grams per cubic centimeter is mudstone, greater than 6800 grams per cubic centimeter is
sandstone, but can also be found in the use of impedance lithology distinguish, in histogram lithology overlap
region remains to distinguish the effect be affected.
Through the above process, we can build low-impedance model Figure 5-2-19 even Inami impedance
model can be seen in the initial model is reasonable, and there is no obvious outliers, and finally through the
congruency map and seismic inversion can ability to distinguish thin geostatistical inversion seen stronger,
higher accuracy (Picture 2).
