Use of Satellite Data for Feasibility Study And Preliminary Design Project Re...IJERDJOURNAL
ABSTRACT: In the developing countries like India, need of infrastructure is very high as compared to the available resources. The various organizations put their demands to state and center government for sanction of their project, government depends upon its various department to provide an approximate cost so that priorities can be assigned. The conventional procedure depends upon the land surveying, collection of data from various departments resulting in delay in necessary decision making or some time shelving due to unreasonable cost estimate due to field data being very old. Survey of India, The National Survey and Mapping Organization single handily taking this responsibility thus up gradation of data is far behind the actual development. From the satellite data, which is available in the form of images and terrains (even in 3d LiDAR points for some areas) is very useful for Feasibility Study, and Preliminary Project Report. In the present study natural drain named „Chai Nala‟ meanders through the prime property of Greater Mohali Area Development Authority (GMADA) thus making a big chunk of commercial land inoperative. It was proposed to straighten and channelize to reclaim the land from drain regime. Being the precious land department wanted the most economical and technically sound design without taking any risk. It was decided to counter check the hydraulic data, ground profile, acquired from the Punjab Irrigation Department with the satellite data and Differential Global Positioning System (DGPS). The data from the Google Earth was acquired using Cad Earth software and water shed analysis was carried out using Autodesk Civil 3D software. Comparison of results shows that this technique is quite useful and can be for preliminary feasibility and project preparation. Thus saving huge money and time.

Seismic attributes are being used more and more often in the reservoir characterization and interpretation processes. The new software and computer’s development allows today to generate a large number of surface and volume attributes. They proved to be very useful for the facies and reservoir properties distribution in the geological models, helping to improve their quality in the areas between the wells and areas without wells. The seismic attributes can help to better understand the stratigraphic and structural features, the sedimentation processes, lithology variations, etc. By improving the static geological models, the dynamic models are also improved, helping to better understand the reservoirs’ behavior during exploitation. As a result, the estimation of the recoverable hydrocarbon volumes becomes more reliable and the development strategies will become more successful.

Velocity analysis and depth conversion in the offshre kaboudia permitGuizani Aymen
Accurate depth conversion is vital to map depth and thickness of subsurface layers interpreted from seismic reflection images and for structural model building, but depth conversion requires good quality seismic velocity information. The number and distribution of wells with velocity information in the Kaboudia permit is poor, in contrast, a 3D post-stack seismic reflection data covers the area of interest and providing a good distribution of stacking velocities.
Seismic stacking velocities are an outcome of seismic processing and are thus not a direct measurement of the speed of sound in rocks. To improve the quality of the depth conversion workflow in this area characterized by a complex geological environment a methodology is suggested to calibrate stacking velocities against borehole velocity measurements. This would allow the widespread stacking velocities to be used to create a more constrained velocity model of the interpreted layers in the Kaboudia permit.
The methodology consist of computing calibration coefficient resulting from comparing seismic velocities and wells data then Multiply depths derived from stacking velocities by calibration coefficient mapped with different options of gridding. the robustness of this process is assessed by putting the resulting converted surfaces in contrast with other simple depth conversion workflows and by relative errors to wells and uncertainty analysis.

Structures and hydrocarbon prospects in emi field, offshore niger deltaeSAT Journals
Abstract The Niger Delta is ranked among the world’s major hydrocarbon provinces in the world. Oil and gas in the Niger Delta are mainly trapped in sandstones and unconsolidated sands in the Agbada formation and the structural traps are not easy to map precisely because they are very slight, not obvious and very complicated. The main aim was to determine the structures and hydrocarbon prospects in Emi-field, off shore Niger Delta using seismic data integrated with well logs. Four (4) horizons namely L1, L2, L3 and L4 were selected and structural maps drawn for each of the horizons. Fault closures of high quality hydrocarbon prospects were identified and delineated. The integration of seismic data with well logs greatly improved the extent of accuracy and exactness of structural maps in hydrocarbon prospects and its development in Emi Field. Key words: Structures, hydrocarbon prospects, Emi Field, Niger Delta

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.
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.
The October 2004 Mw=7.1 Nicaragua earthquake: Rupture process, aftershock loc...Gus Alex Reyes
The subduction zone off the Nicaragua
coastline has been the site of several large
earthquakes in the past decades, including
the 1992 tsunami earthquake that was
anomalous in the size of the tsunami relative
to moment release [Kanamori and
Kikuchi, 1993]. As a focus site for both
the MARGINS-SEIZE and SubFac initiatives,
it is an area of keen interest for
scientists interested in earthquake rupture
and volcanic processes.
Airborne gravity anomaly over Delta State in the Niger delta basin of Nigeria has been interpreted to obtain the structural trends/types and depth to basement in the state. The residual gravity anomaly obtained from a second order polynomial operation on the observed field data was enhanced by a first order filtering operation based on the regional geology. This was converted to a gridded data and analyzed qualitatively to reveal NS and EW trending subsurface structures. Inverse and forward modeling using Oasis Montaj software were applied to selected portions using geological models of sphere and dyke to reveal syncline and anticline structures at depths of between 2005 m to 7372 m, with density contrast of between 1.12 gcm-3 and 2.70 gcm-3. The Euler deconvolution operation with a structural index of one, reveal depths between 124.2 to 16,000 m. The results show that the maximum depth to basement in the area occurs in the northern part of the state with maximum depth of 16,000 m.

Hydrocarbon potential of the Borno Basin through Electrofacies and depositional environment analysis was carried out from well log and seismic reflection data to reassess the potential of the Basin thereby justifying the huge financial commitment of the Government. The reflection configuration pattern from the seismic reflection lines is characterized by variation from parallel, continuous and strong amplitude to sub parallel, chaotic discontinuous and low amplitude which indicate a variation from a low energy basinal setting of uniform rate of continental deposition to high energy environment of monolithologic deposits. Furthermore, the derivable log signatures shows a variation from serrated mud/sand to serrated blocky to serrated funnel and bell shapes with depth. This imply a stable massive mud/sand rich basinwide environment to an upward regressive sequence of bar deposit followed by a deltaic estuarine clastic sediment to gradual upward transgressive decrease in grain size to a fluvial point bar deposit. These environments identified from the research are known to be hydrocarbon province.
Edge Detectionand Depth Estimation from Magnetic DataofWadi Araba,Eastern Des...iosrjce
Edge detection, trend analysis and depth estimation techniques are very important steps in the
interpretation of magnetic anomalies. In this paper, the Fast Fourier Transform was applied to showing the
regional and residual sources. Trend analysis was carried out on the Reduced to Pole, regional and residual
aeromagnetic maps to delineate the main tectonic trends dissected the study area. The edges of these sources
is determined by using the tilt angle derivative and standard 3D-Euler deconvolution. The estimated Euler
solutions was plotted on the tilt angle derivative map. A good correlation was noticed between them
indicating that both of them can be contribute in delineating the general structural framework of the area.
These techniques indicate that Wadi Araba is highly affected by the Gulf of Suez rifting system and the Syrian
Arc folding system. On other hand, the area is affected by the Tethyan trend especially the southwestern
corner of this area and it is maintained in regional components. The depth estimation was applied using
analytic signal and Source Parameter imaging techniques. These depth methods show a comparable results.
The depth to the top of the basement sources ranges from about 200 to 4000 m.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software.

------------------------------------------------------ABSTRACT---------------------------------------------------3-D seismic data have been used to delineate a productive zone in “Abjnr” oil field, Southwestern Niger Delta.
The research involved importing digital seismic data into the Seismic Micro-Technology (SMT) software to
generate seismic sections on which faults where mapped. A Horizon was selected prior to loop tying and timing
and posting. Structural maps generated, contoured in time and depth reveals regions with structural highs. The
reservoir area extent was determined using the planimetering software method. The structural maps produced
revealed fault dependent closures at the central portion of the field, which served as possible trapping
mechanism for the reservoir.

PREAMBLE
Seismic structural maps when carefully evaluated hold information such as structural highs, faults
orientation, structural closures, rollovers anticlines among others that define the geometry of productive zones.The
application of seismic reflection technology to the detection of oil and gas fields has been very useful in the oil
industry and profession of exploration geophysics. It can sometimes directly detect boundaries of acoustic
impedance between different fluid layers in a reservoir rock, but an indirect approach is normally employed, and it
involves searching for the traps, such as anticlinal closures within which the oil or gas may be present. Seismic
reflection technology has been applied in exploration geophysics to search for these traps, within which oil or gas
may be present (Kearey and Brooks, 1991).Structural interpretation is an important aspect of the developmental
programme of a field. It has diverse application in many areas of 3-D seismic interpretation among which include:
helping to effectively analyze controlling influences on reservoir geometry, position and hydrocarbon migration
pathways.Sometimes the estimate of reserves may even be dependent on structural interpretation when fluid
contacts located on depth structure maps are needed as inputs in volumetric analysis (Rotimiet al., 2009).The 3-D
seismic data used for this research work was gotten from Chevron Nigeria Limited. The data include co-ordinates
with which the base map was generated. These said data provides a geologist with useful information about the
surface geology with which inferences can be drawn when the need arises for drilling of exploratory, appraisal or
development wells in an area of interest.Adeoye and Enikanselu (2009), confirms that the area extent of the
reservoir that is derivable from the structural map is very important inestimating the hydrocarbon in place.

LOCATION AND BRIEF GEOLOGY OFTHE STUDY AREA
The study area is within latitude 4.10 and 5.40N and longitude 5.00 and 5.50E. The basic lithostratigraphic
units are the Benin, Agbada, and Akata formations (Riejerset al., 1997).Most known traps in Niger Delta
fields are structural, although, stratigraphic traps are not uncommon. The structural traps developed during
synsedimentary deformation of the Agbada parallic sequence (Evamy et al., 1978, Stacher, 1995). Structural
complexity increases from the north (earlier formed depobelts) to the south (later formed depobelts) in
response to increasing instability of the under-compacted, overpressured shale. Doust and Omatsola, (1990)
describe a variety of structural trapping elements, including those associated with simple rollover structures;
clay filled channels, structures with multiple growth faults, structures with antithetic faults, and collapsed
crest structures. On the flanks of the delta, stratigraphic traps are likely as important as structural traps (Beka
and Oti, 1995).

III. MATERIALS AND METHODS
The basic materials that were made available for this research included 3-D seismic data, base map
(Figure 1) of the site of study and kingdom suite software (Seismic Micro Technology) 8.2 version. The base
map consists of equally spaced lines (inline and cross line), each representing a seismic section. On the sections,
faults were picked and a horizon was also mapped. Loop tying with timing and posting were also carried out.
Fault Picking
Picking of faults is an integral aspect of this research work. It was done after attributes like lines quality,
depth, reliable imaging and structural complexities where carefully examined and understood.Consequent upon
these points mentioned above, while picking faults on the seismic sections attributes such as abrupt endings of
reflections, upthrown with relative downthrown, abrupt changes in dip directions, misclosures in tying reflections,
distortion / displacement of reflections and disappearance of reflection below suspected faults lines were carefully
looked out for:
Mapping of Horizon
A horizon was selected. It reflected on both inlines and crosslines. The horizon is tracking between
2.309 and 3.101seconds amplitude time and it occurring between depths of9600 ft (3072m) and 12580 ft (4112m).
Loop Tying
This involves transferring whatever features shown on the inlines to the crosslines and vice-versa. The
concept of tying of loop helped in projecting the horizons being mapped into areas where well control may not
exist and establishing a relationship between the trace of surfaces seen on seismic lines.
Timing and Posting
Timing was done by reading reflection time on the horizon picked at intervals. The values for time
obtained were therefore posted at appropriate points on the seismic situation map. The top and bottom of
horizon picked were timed at every change in about 0.005 milliseconds. This represents the arrival time of the
reflection from the sea level. Faults were also posted to their corresponding location on the base map. All the
marked locations were then linked with thick smooth lines.

Time – Depth Conversion
This involved the conversion of the acoustic wave travel time to actual depth, based on the acoustic
velocity of subsurface medium. This conversion permits to produce depth and thickness maps of subsurface
layers interpreted on seismic reflection data. These maps are crucial in hydrocarbon exploration because they
permit the volumetric evaluation of oil or gas in place.In converting the time to depth, T-D conversion (check
shot survey) was used. First and foremost, the time structural map was generated and then using the check short
survey a new gridded horizon was formed. It is on this new horizon that depth structural map was generated by
contouring in depth.
IV.
RESULTS AND DISCUSSION
Faults and Their Orientations
Faults are good migration paths for hydrocarbon into reservoir rocks. They are important aspect of
many reservoirs particularly in the way they control the movement of hydrocarbon. There are threemajor growth
faults, X and Y shown in figure 2, then Z shown in figure 3. These growth faults are trending east-west but
dipping southerly. These major growth faults are synthetic.Faults a, b and c areminor but also synthetic faults
which tend to ebb after some distance across the field. Faults U and V are antithetically closing up with others to
form closures and indications of rollovers and collapsed crest. Rollover anticlines are good traps for
hydrocarbon. Therefore the trapping mechanism will be depending on the faults and the anticlinal structures
which collectively form the structural closures as shown on the structural maps.

Structural Maps
The evaluated horizon is tracking between 2.309 and 3.101seconds amplitude time and it occurring
between
depths of 9600 ft. (3072m) and 12580 ft (4112m). The delineated reservoir is timed below 2.76
seconds (Figure 4) and a depth of about 11125 ft (3560m). The generated structural maps (Time and depth) have
fault polygons imposed on them before they were contoured. They show the two-way travel time of the horizon
and also the geometry of the reflector. These maps reflect geological information such as anticline with their
respective syncline and the geometry of the faults as they relate to migration and accumulation of hydrocarbon.
There are indications of rollover anticlines. The area shaded red on the central portion of the depth map (Figure
5) is the delineated pay zone of the reservoir. It is observed that time and depth contour values increases towards
the south-western direction, but decreases towards the north-eastern direction. Therefore, the study area has
more sediment deposited in the south-western part of the map, compared to the north eastern direction.It should
be noted that the potency and accumulation of the hydrocarbon depends in some ways on the trap and cap rock.

The thickening of sediments towards the area wherethe reservoir is delineated could specify that the
resource is overlain by a thick cap rock that is protecting it till abstraction. The orientations of the faults are
further expressedon the structural maps, just as explained on the seismic sections earlier on. The antithetic faults
(U and V) juxtapose the synthetic fault (Y) within the field to form closures at the central portion of the mapped
area. There are rollover anticlines that could form trap for the hydrocarbon.

V.
CONCLUSION
Delineation of a productive zone on a reservoir in “Abjnr” oil field in the Niger Delta has been
carried out. The mapped area has structural high with well oriented faults and rollover anticline at the central
portion. These features, with the gradient of that portion as shown by the contour lines on the depth structural
map suggest a possible migration path and accumulation of hydrocarbon in that portion. It is therefore
concluded that the central portion of the field has structural highs sandwiched between the growth faults which
can be responsible for possible hydrocarbon accumulation. This is gainfully supported by the cited rollover
anticline on the delineated portion.
VI.
RECOMMENDATION
It is therefore recommended that information, such as hydrocarbon saturation (Sh) and reservoir
thickness (h) should be derived using wire-line logs, to enable the estimation of the recoverable Oil-In-Place in
the reservoir.
