Areas of Expertise

Diverse experience with the use of numerical approaches to evaluate oil and gas reservoirs and properties.

Reservoir Simulation: Extensive experience in reservoir simulation studies of oil and gas fields throughout the world.  Routinely involved with all facets of simulation such as initial model design and conceptualization, cost and timing estimates, model construction, history matching, calibration, and final project documentation.  Types of simulation models include full-field, segment, and single well models including horizontal and highly deviated well studies.  Experience with black oil, compositional, and thermal formulations.  Types of studies range from waterflood development to gas storage project development.  One such study is:
Pescada field, offshore Brazil
Conceptual full-field, complex fluid modeling

Integrated Reservoir Studies: Optimization of field development through the integration of various earth science tools and disciplines.  Integrated geological, petrophysical, geostatistical, geophysical, and reservoir and production engineering data into a comprehensive numerical reservoir simulation model.  These models are then used to help optimize the reservoir exploitation plan by searching for the scenario that tends to maximize the field (net present) value.  One such study is:
Dos Cuadras field, offshore California
Full field, fully integrated study

Fluid Characterization: Conducted numerous fluid characterizations using commercially available reservoir fluid analysis packages.  Typically tuned Peng-Robinson equations of state for subsequent use in various compositional and black oil models.  One such study is:
Safaniya and Berri fields, Saudi Arabia
Fluid characterization for separator design

Economic Evaluations: Economic evaluation experience in various geographical areas.  Experience includes the preparation of sales packages for divestiture.

Other Areas of Proficiency

Material Balance Studies: Evaluation of reservoir size and performance using material balance techniques.  Other experience involved teaching in-house material balance schools to engineers while at Chevron.

Field Operations: Four years operations experience in light and heavy oil reservoirs in the San Joaquin Valley, California.

Steamflood Production Operations: Experience involved surveillance of ongoing steamflood and cyclic steam projects. Infill drilling, workovers and profile control were conducted routinely.

Simulation Experience (Partial List)

15,000 Ft. Zone, Trinidad & Tobago
Compositional (Geoquest’s PVT/E300) A 3-Parameter Peng-Robinson EOS was tuned to arrive at a suitable fluid characterization of this extremely volatile oil sample.  Simulation models were built and used to compare results generated with E100 (black oil) and E300 (fully compositional).

Anahuac formation, Bishop, TX
Aquifer (Sandia Lab’s SWIFTIII) Updated historical injection and re-ran previously constructed model to evaluate pressure increases at previously drilled well locations (artificial penetrations).

Brazos A-19 Field, Offshore Texas
Gas/Condensate (Geoquest’s ECLIPSE) This model was constructed in order to estimate the recovery of oil and gas attributable from the well for a specified period of three years.  A short history match (approximately two weeks of data) was used in order to calibrate the model to known tubinghead pressures and rates.  The results of this work were used to help determine damages due to a business interruption, shortly after the well was placed on production.

Brea Olinda, California
Black Oil (Geoquest’s ECLIPSE) Involved in the original design and implementation of the study.  This model was constructed to help our client design a waterflood within this reservoir that has various large compartmentalized fault blocks.  This integrated study provided our client with an updated geological and petrophysical model by incorporating revised geological mapping and petrophysics.  The simulation model helped to determine the required number and locations of new injection and production wells.

Carrasco field, Bolivia, S.A.
Compositional (Geoquest’s PVT/E300) Completed a fluid characterization using 3-parameter Peng-Robinson equation of state.  Used the fluid model in Eclipse E300 to determine expected recoveries of various components throughout the life of a proposed gas re-injection project.

Casma-Anaco field, eastern Venezuela
Black Oil (Geoquest’s ECLIPSE) Our client outsourced the simulation portion of this field study to Ryder Scott Company.  The client’s geology and PVT data were used to construct the simulation model, which in turn was used to evaluate the development of an up-dip gas-cap, in order to properly position a new horizontal well.

Confidential Field, North Sea
Black Oil (Geoquest’s ECLIPSE) This model was constructed by one of two principal participants in this giant field located in the North Sea.  Our client, the other major participant, requested that we review and revise the model incorporating various alternate geological models (e.g., NTG and permeability distributions).  This work was conducted in order to check for bias in the model, and the results were used in support of equity negotiations.

Dacion field, Venezuela
Black Oil (Geoquest’s ECLIPSE) This model was constructed to assist in the field development plan of this heavy oil reservoir using horizontal wells.  Contribution to this project primarily concentrated on the model-grid construction phase.

Diatomite, Lost Hills, CA
Dual Porosity, Naturally Fractured (Chevron’s NFRS) Modeled fractured wells in a highly anisotropic reservoir.  The model was used to evaluate the effect of well spacing and infill drilling. It was also configured to evaluate waterflood potential.

DOS Cuadras field, CP/DP Zones, offshore California
Black Oil (Geoquest’s ECLIPSE) This model was constructed to help our client design a waterflood for sands that were nearing depletion through primary recovery.  This integrated study provided our client with an updated geological and petrophysical model by incorporating geophysics, petrophysics, revised geological mapping, and geostatistics.  The simulation model helped to determine the required number and locations of new injection and production wells.  The effects of various operational parameters, such as future injection rates, were also investigated.

East Breaks Blk 157, offshore, LA
Black Oil (Geoquest’s ECLIPSE) Constructed full field model of this reservoir to estimate expected recovery.  Sensitivities to the degree of aquifer influence and the various completion alternatives were investigated.  The model incorporated radial local grid refinements to model the coning behavior of the wells.

East Cameron 334, West Cameron 580, offshore LA
Black Oil (Geoquest’s ECLIPSE) A full-field model was constructed and history-matched to evaluate the impact on ultimate recovery (to separate interest owners) due to alternative competitive operating strategies.  The representative model was based on well penetrations, seismic amplitude maps, observed production performance including tubing-head pressures, and inferred rock compaction effects.  Additional cases were run to help to optimize economic the benefit of alternative future development strategies.

East Painter, WY
Gas/Condensate (Chevron’s CLASS) Various runs were conducted using IBM and Cray to test model configuration, timing and memory requirements.

Escondido field, Bolivia, S.A.
Compositional (Geoquest’s PVT/E300) Completed fluid characterizations of various reservoir fluid samples using a 3-parameter Peng-Robinson equation of state.  Representative Eclipse E100 “include” files were generated and supplied to the client and subsequently used in predictions conducted by the client.

Eugene Island Blk 182, offshore LA
Black Oil (Geoquest’s ECLIPSE) A full-field model incorporating local grid refinements was constructed.  The model was history-matched and used to evaluate the impact on ultimate recovery due to both water coning and gas coning effects.  Additional cases were run to evaluate alternative production practices.

Freedom field, Wilkinson Co., MS
Compositional (Geoquest’s PVT) Prepared a cursory fluid description for use in an Eclipse E100 model by characterizing the fluid using the PVT program.  A 3-parameter Peng-Robinson EOS was used to match the PVT model results with the lab observed data.

Grand Isle 102, offshore, LA
Black Oil (Geoquest’s ECLIPSE) Constructed full field model of this faulted reservoir.  The model was used to determine expected recovery of the reservoir. Sensitivities to the tubing design and the degree of aquifer influence were investigated.

Green Canyon Block 69 Field, Offshore Louisiana
Black Oil (Geoquest’s ECLIPSE) This model was constructed in order to arrive at a productivity estimate based on the log-derived porosity and permeability distribution.  This quick look model was used to determine preliminary rates and recovery estimates to help in the go/no-go decision to sanction the well.  A series of sensitivity cases were run to evaluate various permeability models (different permeability “caps” were used with the same permeability-porosity crossplot).

Green Canyon Block 161, Offshore LA
Black Oil (Geoquest’s ECLIPSE) Constructed a model of a potential acquisition for the client. The model construction included relative permeability data normalization/preparation, fluid characterization (using PVT), vertical flow tubing table generation, and configuration for modeling the seafloor/platform piping network.  The model was transferred to the client to run various prediction cases.

Green Canyon Blocks 472, 473 and 516, Deepwater GOM
Gas/Condensate (Geoquest’s ECLIPSE) These blocks are also known as the King Kong / Yosemite deepwater project.  A series of 3D black oil, homogeneous and isotropic reservoir simulation models were created to determine the effect of various reservoir drive mechanisms on reservoir performance and recovery.  The mechanisms investigated were depletion, compaction, and aquifer drive scenarios.

Hillbig, south Texas
Gas/Condensate (M.O.R.E.) Assisted a client in debugging and optimizing a model of a gas storage project. The model was constructed by a competitor consulting firm.

Hosston, El Dorado, AR
Aquifer (Sandia Lab’s SWIFT386) Constructed a homogeneous model to determine plume size and location (after 10,000 years) to assess the viability of the disposal project.

Hustead field, Fayette Co., PA
Black Oil (Geoquest’s ECLIPSE) This project involved the construction of a model of a proposed gas project in a depleted gas reservoir in Pennsylvania.  The client required an assessment of existing gas in place, as well as an optimal development plan based on certain injection and production requirements.  A probabilistic model (geostatistics) was constructed to account for spatial variations in rock properties.

Karakuduk Field, Kazakhstan, Former Soviet Union
Black Oil (M.O.R.E. and ECLIPSE) A model originally constructed by a competitor-consulting firm, using the M.O.R.E. simulator, was converted into an ECLIPSE model.  The purpose of this conversion was to allow Ryder Scott to update/revise the geological interpretation while incorporating much of the work conducted during the prior study (e.g., PVT and relative permeability).  Certain shortcomings of this previous model were identified and corrected in the ECLIPSE model.

Keystone Ellenburger, Winkler Co., TX
Dual Porosity (Geoquest’s ECLIPSE) Constructed a representative full field model.  Effects of various unknown parameters (e.g., DZ, sigma) were investigated.

Main Pass 299, offshore, LA
Black Oil (Chevron’s CLASS) Radial models were used to evaluate the recovery sensitivity to rock permeability and the presence of shale barriers.

Mestina Grande, south Texas
Gas/Condensate (Geoquest’s ECLIPSE) The gas/condensate was first characterized with a 3-Parameter EOS.  However, a non-compositional model was deemed appropriate for the study. The model was used to evaluate infill-drilling potential.  The model consisted of 5,100 active cells, two layers, and 29 wells.

Miocene sands, Westwego, LA
Aquifer (Sandia Lab’s SWIFTIII) Ran various sensitivity cases to determine the range of injectant density and rate combinations that would allow continued injection under the existing permit application.

Miocene sands, Westwego, LA
Aquifer (Sandia Lab’s SWIFTIII) Updated and refined grid of previous model to evaluate magnitude of numerical dispersion.  Also, the model was used to determine if a refined grid would indicate tendency of plume separation into dense and buoyant components.

Murban field, United Arab Emirates
Compositional (Geoquest’s PVT) Over 24 separate fluid analysis reports were reviewed in order to develop a detailed compositional fluid description.  Approximately 16 Peng-Robinson equations of state (EOSs) were characterized (tuned) for selected samples.  These EOSs were used in subsequent compositional models.

NPR No. 1, Elk Hills field, San Joaquin Valley, CA
Various model types Reviewed models of Elk Hills field reservoirs constructed by various consulting companies.  This review included the evaluation of the model construction, history match and conclusions.  Some of these models were updated and sensitivity cases were run.

Pescada field, offshore Brazil
Compositional/Black Oil (Geoquest’s ECLIPSE) Fluid characterizations were performed on several samples in order to obtain a representative fluid model.  The reservoir exhibits significant compositional variation with depth and is also highly dependent on the temperature gradient through the relatively large oil column.  Another unconventional aspect of the reservoir is that it is undersaturated throughout, even though it contains gas at the top and oil at the bottom of the interval.  Thus, no gas-oil contact exists.  A black oil model was created from the fluid modeling work in order to estimate the recovery of these hydrocarbons.

Pt. Pedernales Field, Offshore California
Black Oil (Geoquest’s ECLIPSE) Major participant in the design, construction and history match of a full field model of this complex, naturally fractured, Monterey reservoir.  A dual porosity formulation was used to model the reservoir, which appears to actually exhibit a triple porosity behavior.  Deviated wells (26 total) with about 15 years of history added to the complexity of the overall model.  The simulation model was used to estimate an “effective” Original-Oil-In-Place and to estimate the remaining recovery from the field.  In addition, the model was built to determine the critical factors relating to recovery from the Monterey reservoir within the field, which would then be incorporated into a model of an offsetting Monterey reservoir.

Prinos North field, offshore Greece
Black Oil (Geoquest’s ECLIPSE) A full field model was constructed and history-matched to evaluate the impact of water coning on ultimate recovery of an extended reach horizontal well. Various geological model assumptions were tested to help formulate the current geological interpretation.  Prediction cases were run to optimize the economic benefit of the future development plan.

Redmond Creek field, Liberty Co., TX
Compositional (Geoquest’s PVT) Prepared an EOS fluid model for use in an Eclipse E100 model by characterizing the fluid sample using the PVT program.  A 3-parameter Peng-Robinson EOS was used to match the PVT model results with the lab observed data.

Risha Field, Jordan
Black Oil (Geoquest’s ECLIPSE) This model was part of a comprehensive study conducted by a competitor-consulting firm.  The model was reviewed and checked for consistency and appropriateness.  Various model configuration parameters were changed to evaluate the sensitivity to various uncertain reservoir parameters.  This work helped to quantify the reliability of the history match and indicated that the gas originally in place, “as confirmed” by the model, was optimistic.

Rotherwood field, Harris Co., TX
Black Oil (Geoquest’s ECLIPSE) This model was constructed to model an existing gas storage field.  The model was used to help quantify the current gas in inventory and to assess various development alternatives to improve the performance of the storage operations.

Safaniya & Berri fields, Saudi Arabia
Compositional (Chevron’s CPCP) Completed fluid characterizations of several samples using 3-Parameter Peng-Robinson Equation of state.  Various numerical separator tests were conducted to obtain estimates of properties of the fluid within the separator.  The results were used to specify, design and recommend over $50MM welltest separator facilities.

Santa Clara field, Lower Repetto Reservoir, offshore California
Black Oil (Geoquest’s ECLIPSE) This model was designed to help manage the further development of this offshore California field.  The main emphasis of the model was to evaluate infill well development potential, particularly the interference caused by these new wells.  The results of the model were used to design a drilling schedule with improved economics by requiring fewer wells than originally anticipated by our client.

Santa Clara field, Upper Repetto Reservoir, offshore California
Black Oil (Landmark’s VIP / Geoquest’s ECLIPSE) The model was a major revision on an older VIP model constructed by Unocal.  The model was re-history matched using updated model geometry and production.  By properly tracking the encroachment of the aquifer and the further development of the gas gap, the model results were used by the client to help optimize the future field development.

Ship Shoal Blk 301, offshore, LA
Black Oil (Geoquest’s ECLIPSE) Constructed a full field model which incorporated two separate structures which were in pressure communication through a common aquifer.  The model was used to determine the impact of the offset operators production on the ultimate recovery from the main structure (operated by our client).  Sensitivities were also conducted to determine effect of alternative completion scenarios within the main structure.

Sierra Chata field, Neuquen province, Argentina
Gas/Condensate (Geoquest’s ECLIPSE) Constructed a full field model to determine the relative contribution of very thick, tight layers interspersed with very good quality, thinner pay intervals.  The model was used to help determine the amount of the total reserves to be placed in the proved and probable categories.

South Ellwood Field, Offshore California
Black Oil (Geoquest’s ECLIPSE) Designed, constructed and history matched a full field model of this complex, naturally fractured, Monterey reservoir.  Various aspects of this reservoir make it more complex than most.  API oil gravity varying from a minimum of 15 ?API to a maximum of 32 ?API, varying both areally and vertically, as well as a tilted Oil-Water contact were incorporated into the model.  Highly deviated wells (32 total) with more than 30 years of history also added to the complexity of the overall model.  The simulation model was used to estimate an “effective” Original-Oil-In-Place and to estimate the incremental recovery from drilling additional wells in an “extension” area, east of the field.

South Marsh Island Blk 174, offshore LA
Black Oil (Geoquest’s ECLIPSE) Assumed the responsibility for a project halfway through completion.  Some modifications were made, to the essentially history-matched model, in order to continue the project with prediction runs.  While working closely with the client, various development scenarios were considered to determine the most beneficial plan.

Stevens, Elk Hills, CA
Compositional (Chevron’s CHEARS) Conduct sensitivity runs evaluating the effect of different operating conditions on product yields.  The model included gas recycling.

Teague field, Blinebry zone, Lea Co., NM
Black Oil/Compositional (Geoquest’s ECLIPSE / PVT / E300) A 40-acre representative pattern model was built and history-matched in the black oil mode.  This 16-layer model conceptually represented the relative improvement in connectivity when a 20-acre infill well was added.  After the history match, the model was converted to a 10-component fully compositional model. A Peng-Robinson EOS was developed to represent the fluid in the compositional model. Various injection configurations were modeled including CO2, N2, HC gas, flue-gas, and water.

Temblor Sands, Coalinga, CA
Thermal-Compositional (Chevron’s SIS-3) Steeply dipping reservoir (55) with gas cap and aquifer.  Modeled optimum injection scenario of a proposed $27 million steamflood.  This was the first model at Chevron to use corner-point geometry with the SIS3 code.

Travis Peak, east Texas
Dry Gas (Geoquest’s ECLIPSE) Constructed a full field model incorporating over 100 wells.  The model was used to help evaluate the field-average permeability (for tight-gas sand designation).

Valentine Field, Lafourche Co., Louisiana
Black Oil (Geoquest’s ECLIPSE) Supervised and helped design a 3D full field model to estimate current conditions and remaining gas in place.  Uncertainty of Oil-Water contact, aquifer strength, and fault communication required the use of a reservoir simulation study.  The model was also used to estimate the recovery potential from two proposed up-dip well locations.

Various fields, northern Kuwait
Black Oil (Geoquest’s ECLIPSE) Various models were reviewed and checked for consistency and appropriateness.  Some of these models were revised and streamlined and run to investigate the sensitivity to various uncertain reservoir parameters.

West Lovington, Lea Co., NM
Black Oil (Geoquest’s ECLIPSE) Built and ran a small, representative model to evaluate the recovery potential of this reservoir and to help assess the original in-place hydrocarbons.

Areas of Expertise

Over 41 years of experience in the oil and gas industry, mainly in reservoir engineering.  Have been involved in numerous projects over the years requiring the application of technical analysis in both engineering and geological disciplines.  Have served as the lead engineer for several of Ryder Scott’s major clients and developed multi-discipline asset teams to accomplish major reservoir evaluation projects.

Reservoir Engineering:  Broad experience in traditional reservoir engineering applications such as decline curve analysis, volumetrics, log analysis, well test analysis, material balance, pressure transient analysis, PVT analysis, and other reservoir engineering applications.  Have applied these techniques in a broad range of engineering assignments to gain a high proficiency with standard reservoir engineering tools.  Have analyzed reservoirs producing under primary, secondary and tertiary recovery mechanisms.  As a result of this background, can determine the best method to apply to achieve a solution to both routine and complex reservoir problems.

Integrated Reservoir Studies:  Have worked extensively with geologists and geophysicists on projects requiring the consolidation of interpretations of all types of data into an integrated answer that fully describes the best solution to a reservoir evaluation.  Through these projects have developed a working knowledge of geological and geophysical concepts to allow for a better understanding of the techniques required for the most accurate reservoir characterization coupled with reservoir engineering applications that will lead to a complete integrated reservoir study that incorporates the input from both the engineering and geological disciplines.

Economic Evaluations:  Have completed many oil and gas economic evaluations for use in several different types of financial applications.  Bank loan requirements, SEC filings, acquisition and divestiture transactions, estate tax requirements, initial public offerings, internal company financial planning and various other projects have relied on these economic evaluations as a basis for financial decisions. Have developed these economic evaluations using both in-house cashflow software developed by Ryder Scott and commercial programs more widely used in the industry.

Reserve Certifications:  Work with the SEC and WPC/SPE reserve definitions on a daily basis and therefore have developed a strong familiarity with the application of these definitions in the classification of reserves. Have also dealt with the reserve definitions set by other exchange commissions such as those in Canada, Hong Kong and London. Have had numerous dealings with the U. S. Securities and Exchange Commission on behalf of Ryder Scott clients.

Acquisition and Divestiture Work:  Have conducted numerous reservoir evaluation studies for use in both acquisitions and divestitures of oil and gas properties for many of Ryder Scott’s clients including the United States Department of Energy, Apache Corporation, Louis Dreyfus Natural Gas, and Union Pacific Resources.  Have been involved in all aspects of data room procedures both setting up data rooms for the presentation of work performed by Ryder Scott for divestitures of client properties and have visited many data rooms to gather data for potential acquisition studies for clients.  Fully understand the concept of short deadlines and highly confidential work involved in most data room related projects. Aware of the business and financial aspects of both acquisitions and divestitures and the importance of the due diligence process.

Initial Public Offerings:  Have been involved in several initial public offerings (IPO) of clients and understand the need for complete documentation and disclosure of work in these types of situations which come under intense public scrutiny by regulatory agencies and the financial community. Have assisted clients with both the reserves evaluation and financial aspects of initial public offerings.

Areas of Expertise

Nearly 40 years of reservoir engineering experience with a major oil company and a leading engineering consulting company.  Have been involved in numerous projects over the years requiring the application of technical analysis from the engineering, geophysical, and geological disciplines.  Have served as the lead engineer for several of Ryder Scott’s major clients and developed multi-disciplined asset teams to complete major reservoir evaluation projects.

Reservoir Engineering:  Broad experience in traditional reservoir engineering evaluation techniques such as decline curve analysis, log and volumetric analysis, well test analysis, material balance calculations, PVT analysis, infill drilling analysis, and other reservoir engineering applications.  Have applied these techniques in a broad range of engineering assignments to gain a high proficiency with standard reservoir engineering tools.  Have analyzed reservoirs producing under primary recovery, secondary recovery (including various methods of pressure maintenance and traditional waterflooding), tertiary recovery mechanisms (including CO2 injection and thermal projects), and horizontal wells producing from unconventional reservoirs.  As a result of this background, can determine the best method to achieve a solution to both routine and complex reservoir problems.

Integrated Reservoir Studies:  Have worked extensively with petrophysicists, geophysicists, and geologists on projects requiring the consolidation of interpretations of all types of data into an integrated answer that fully describes the best solution to a reservoir evaluation.  Through these projects, have developed a working knowledge of various geoscience concepts to allow for a better understanding of the techniques required for the most accurate reservoir characterization coupled with reservoir applications that will lead to a completely integrated reservoir study, incorporating all disciplines.

Reserve Certifications:  Intimately familiar with the SEC and WPC/SPE reserve definitions, and the application of these definitions to the classification of reserves.

Economic Evaluations:  Have completed many oil and gas economic evaluations for use in many different types of financial applications.  These include, but are not limited to, bank loan requirements, SEC filings, acquisition and divesture transactions, estate tax settlements, initial public offerings (IPO), and internal financial planning.   These economic evaluations have been developed using both our in-house cash flow software developed by Ryder Scott and other commercial programs used widely in the industry.

Acquisition and Divesture Work:  Have conducted numerous reservoir evaluation studies for use in both acquisitions and divestures of oil and gas properties for many of Ryder Scott’s clients, including the United States Department of Energy, the Minerals Management Service, Apache Corporation, Devon Energy Corporation and Santa Fe Snyder Corporation.  Have been involved in all aspects of data room procedures, both setting up data rooms for the presentation of work performed by Ryder Scott for divestures of client properties and have visited many data rooms to gather data for potential acquisitions by our clients.  Fully understand the concept of short deadlines and highly confidential work involved in data room related projects.  Aware of the business and financial aspects of both acquisitions and divestures and the importance of the due diligence process.

Initial Public Offerings:  Have been involved in several IPO’s of clients and understand the need for full and complete documentation and disclosure of our reserve evaluation process in these filings with the SEC, which come under intense public scrutiny by regulatory agencies and the legal and financial communities.  Have interacted with all parties involved in these filings, including our clients, accountants, attorneys, and the SEC.

Summary of Employment

Ryder Scott Co. LP     1976 to Present
Technical Coordinator – Advising Senior Vice President
Joined Ryder Scott Company as a reservoir engineer in 1976.  Became a Vice President and Stock Holder in 1979.  Elected as a Group Vice President in 1990 and as a Senior Vice President in 1998 and recently named Advising Senior Vice President in 2015.

During this entire period, have prepared reservoir and economic evaluation studies for numerous clients.  These studies have included, but are not limited to, a determination of oil, gas, condensate, and plant product reserves for property appraisals, analysis of water flood and pressure maintenance projects, EOR projects involving the injection of CO2, thermal projects involving cyclic steam injection, steam floods, and fire floods, infill development drilling projects utilizing conventional wells and horizontal wells, and acquisition projects.  Clients have included independent and major, domestic and international E&P companies of all sizes, banking and insurance institutions, governmental agencies, investors, and other individuals.

Since 1984, have supervised and coordinated the efforts of a group of reservoir engineers working on various engineering and evaluation projects.  Have served as the technical advisor for these individuals and others within the company.

Exxon Co. U.S.A.     1974 to 1976
Reservoir engineer in the Kingsville, South Texas Production District.  Primary responsibilities included reservoir surveillance for several large oil and gas fields in South Texas, initiate workover and recompletion proposals, and prepare the economic justification for production facility changes and the drilling of development wells.  Fields involved both competitive and non-competitive oil and gas reservoirs.

Worked on a project to determine the extent of pressure communication among various “stacked” Frio sands due to wellbore mechanical problems, and to determine the extent to which a large, unitized gas reservoir (1.5 TCF) might be involved.  I worked with engineers from Exxon Production Research Company, who were developing the noise log as a qualitative and quantitative tool, and selected more than 60 wells in which to have noise logs run.  I was responsible for evaluating the results of these logs and recommended repair procedures where necessary.  At the conclusion of this project, I made a presentation of my results at a technical meeting attended by Exxon’s South Texas Division engineers and geologists.

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, Egypt – Reserves 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, Kuwait – Audit 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, Kuwait – Audit 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, Qatar – Reserves 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, Russia – Reserve 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, Ukraine – Full 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 Tobago – Reserve 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, California – Reserves 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, California – Reserves 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.

Areas of Recent Evaluations – Simulation Studies

West Clear Lake Gas Storage Field, Harris County, Texas – Water 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 California – Proposed 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, Ecuador – Constructed 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.

Undertook a fine scale geological modeling, simulation and history matching project to increase a client’s understanding of a slumped area within a field in the deep water Gulf of Mexico.  Essentially, the project’s objective was to model a range of possible bedding dip and azimuths caused by slumping and understand the impact of this variation on ultimate recoveries.  A Secondary objective was to evaluate the most appropriate upscaling technique to incorporate the slumped region into the full field simulation model.  This project involved the construction of a variety of fine scale models generated from well log and core data, and several full-field scale models utilizing different upscaling and property distribution techniques.  Numerous porosity, water saturation and permeability distributions were generated, including the distribution of full-tensor permeabilities.  Petrel was utilized for this project and was manipulated in a manner to incorporate bedding dip and azimuth variation in the property distribution; a technique that created models that appeared to realistically emulate a slumped region.  The full-tensor permeabilities were generated using the ‘advanced gridding’ option in Petrel.  The fine scale models were subsequently simulated to investigate uncertainty within the area.  The full-field scale models were history matched to an appropriate fine scale model and learnings were taken from both the upscaling and history-matching phases and utilized in the full-field simulation model.
