Selected Field Studies
Angola Offshore Reserves reviews for Gindungo Field in Block 32, Kizomba “A”, “B” & “C” in Block 15 and various fields in Block 18.
Western Desert gas project-Kenz, Khepri-Sethos, Salam, Shams, Tarek, West Falak fields, EgyptReserves and development plan evaluation of multi-field concession. Developed stratigraphic correlation scheme of fluvial to delta-front sandstones consistent with available production and pressure data. Constructed petrophysical model of Cretaceous and Jurassic age sandstone reservoirs that accounted for results of production and drillstem test data. Developed wellbore utilization scheme to maintain production at desired “plateau” level for maximum duration.
Raudhatain and Sabiriyah fields, KuwaitAudit of original oil-in-place estimates and procedures. Demonstrated that trapping mechanism is related more to permeability degradation than to structure. New interpretation suggested that apparent water level conflicts in the field may have been the result of an overly optimistic porosity cutoff and that a more complex stratigraphic model of the reservoir was unnecessary.
Abdali, Bahrah, Ratga fields, KuwaitAudit of original oil-in-place estimates and procedures. Accounted for multiple observed water levels in field being competitively produced across border. Reconciled preliminary seismic structural interpretation with observed well performance.
Al-Rayan field, QatarReserves evaluation incorporating 2D seismic and detailed petrophysical analysis. Results of study used in forecast of future deliverability subject to OPEC quotas.
Tyumen Oil, Orenburgneft Production Association, RussiaReserve audit and categorization. Evaluation of FSU “A, B, C1 and C2” reserves designations and development of risked production profiles based on SPEE proved, probable, possible and potential reserve categories. Developed optimized exploitation program based on risk-adjusted future net income.
Rudovsko-Chervonozavodsky field, UkraineFull reserve evaluation of multi-reservoir gas field. Used FSU-style well logs, core data and drillstem test data to provide estimate of recoverable gas reserves. Study was used to obtain financing for field development.
Trinidad gas project, Trinidad and TobagoReserve and resource evaluation of future national gas supply. Overall coordination of multidisciplinary geoscience team assigned to the project. Developed consistent methodology in deterministic evaluation of developed gas reserves and probabilistic evaluation of undiscovered potential gas resources. Development of risk adjusted future gas production profile.
Elk Hills field, Kern County, CaliforniaReserves evaluation and exploitation potential in the Western 31S and Main Body B Sands. Estimation and reconciliation of original oil in place, cumulative production and injection and remaining gas and oil in place in a thick, turbiditic sandstone sequence that had been produced under gas injection and waterflooding through multiple, commingled completions. The original and current fluid contacts in the field could not be identified on well logs. This study resolved the contacts utilizing log, core and drillstem test data as well as reservoir production and pressure history. The new interpretation explained apparent “excess” gas in the reservoir and resulted in the identification of multiple recompletion and infill drilling opportunities.
Cymric field, Kern County, CaliforniaReserves evaluation and development potential in the Antelope shale. Petrophysical model of a diatomite reservoir containing heavy (12 degree API) crude produced under steam stimulation. Correction of standard open-hole logging suites to account for rapidly varying reservoir lithology and thermal effects.
Additional Areas of Expertise
Simulation Studies
West Clear Lake Gas Storage Field, Harris County, TexasWater drive gas storage field in massive, clean sands of the Frio Formation. Constructed structure and gross and net sand isopach maps used in reservoir simulator. Developed correlations and cross-sections to demonstrate vertical seals and possible areas of communication between reservoir zones.
Dos Cuadras Waterflood, Offshore CaliforniaProposed waterflood in Miocene sandstones on thrust fault related structure. Constructed structure maps accounting for seismically identified reverse and normal faulting of magnitudes ranging from twenty-five to five hundred feet as well as normal faults identified from subsurface correlation not resolvable on seismic.
Fanny Field, Oriente Basin, EcuadorConstructed structure and isopach maps. Developed correlation of individual sand bodies deposited in a fluvial environment. Developed structure maps relating seismic marker to top of reservoir structure. Final structure accounted for overprint of sandstone compactional features on basement related folding.
