Reservoir Management and Consultancy Services
We provide effective petroleum reservoir management consultancy service by employing advanced geosciences and petroleum engineering technologies that ensure adequate reservoir description, reservoir characterization, production enhancement and field optimization for asset management. These services include:

Geology and Geophysics: Seismic Interpretation, Petrophysical Evaluation, Static Reservoir Modelling.
Petroleum Engineering: Material balance and decline curve analysis, production optimization, reservoir simulation and dynamic modeling, well test analysis, reserve estimation and integrated reservoir studies.

GEOLOGY AND GEOPHYSICS
Seismic Interpretation: As part of our involvement in integrated reservoir studies we are skilled in regional 2D and 3D seismic Interpretation. Our workflow includes data management and visualization, well to seismic tie fault interpretation, horizon mapping, generation of fault polygons, velocity modeling, time-depth conversion, structural seismic uncertainty analysis, seismic calibration, definition of hydrocarbon contact and aquifer extents,seismic attribute extraction. In more advanced studies we do seismic inversion and AVO analysis. We incorporate structural geology, sequence stratigraphy, regional geology and sedimentology for an adequate description of the reservoir architecture.This improves the quality of our interpretations. In this stage, we also liaise with the Reservoir Engineers by incorporating pressure data in establishing vertical and lateral reservoir connectivity. This we do with Geographix and Petrel software.

Petrophysical Evaluation: We carry out detailed petrophysical studies using robust, state of the art software, and methods unique to each geologic region. Hence the following are achieved in our petrophysical evaluations: delineation of reservoir and non-reservoir Intervals, determination of average petrophysical properties K, sh, phi-ø, Sw, NTG for each reservoir interval, determination of ranges and Cut-Offs for K, sh, phi-ø, Sw, NTG for each reservoir interval, delineation of the top and base of each reservoir, determination of net pay and hydrocarbon column for each reservoir Interval, fluid contact analysis: OWC, GOC, ODT, GDT, WUT ,delineation of reservoir layers and hydraulic (flow) units, Inter-well correlation of continuous intervals, sedimentological and lithological facies definition based on log, cores and sedimentological interpretation, geostatistical analysis and distribution of petrophysical data in such a manner that respect the measured and log-derived litho-facies and petrophysical data, generation of saturation height function for each reservoir interval, detailed petrophysical reports for each interval of interest.

Static Reservoir Modelling: Our static reservoir modeling is aimed at helping our clients understand their available resources in place and thus serve as an input to reservoir simulation studies.This may entail facie log analysis, EOD interpretation, structural framework model, fault modelling, Horizon making, zonation, layering, facie modelling, data analysis, petrophysical modelling, volumetric calculation.




PETROLUEM ENGINEERING
Our experienced reservoir engineers use proven methods, state-of-the-art software, and technologies, to support our clients in making critical decisions about their asset. Thus our Petroleum Engineering Services includes:

Material Balance and Decline Curve Analysis: Our Material Balances and decline curve analysis are carried out with MBAL software and it entails preliminary dynamic in-place volumes estimation and drive energy confirmation, initial and present contact evaluation based on open-hole/cased hole log, production performance, and 1-D modelling, preliminary DUR estimation, recovery factor (RF) comparison with previous studies and/or literature.

Production Optimization: We understand our client's needs to improve the performance of their asset. Hence our team of experts analyzes the performance of wells and reservoirs, identifies the anomalous behavior of producing wells, generate well inflow/outflow performance models, reviews and design artificial lift where applicable and also identify short-term opportunities. They do this with PROSPER Software.

Reservoir Simulation and Dynamic Modeling: Our dynamic modeling and reservoir simulation study involves:
Initialization which entails the review of equilibration data by blocks, comparison of pore volume (PV) and hydrocarbon pore volume(HCPV) by segments, zone, EOD, blocks, reservoir, comparison of In-place volumes, pseudo logs generation, as well as the Initial simulation run for convergence and stability.
We also match historical production and pressure parameters for black oil, heavy oil, gases, and condensates, to reservoir simulated models. We review HC saturation at end of history by comparing earlier integrated saturation histories and their implications for new wells as well as depletion plan. Our predictions involve a review of hydraulic curves, treatment of wells and facility constraints, well productivity and skin assumptions for existing and new wells, sensitivity runs for different developmental cases, review of selected base case simulation results, quantification of integrated uncertainties and impact on ultimate recovery (UR).
In our development/redevelopment study, we develop data acquisition plan to reduce uncertainty and also produce decision tree economic justification of selected development concepts.

Well Test Analysis and Design: In other to reduce uncertainties and enhance confidence in geologic and petroleum engineering interpretation, our well test analysis and designs are tailored at identifying production problems, providing a direct measurements of the wells actual and potential productivity. We do this by determining reservoir and well parameters such as permeability, distance to boundaries, average pressure, temperature, reservoir heterogeneity and connectivity, skin, productivity index, well-bore storage constant, fluid distribution in the well-bore, flowing pressure in the well-bore, static gradients.
In new fields or special circumstances, we design wells to identify key parameters of the well test, duration of flow phases, determine expected pressure changes, and ensure correct equipment are used.
