Experience
2007-Present NExT, PDVSA, PEMEX, and ConocoPhillips Durango, Colorado
President of Petrophysical Technologies
NExT and PDVSA
Mentoring and teaching subsurface integration for NExT. I was Coordinator for the project portion of the Masters of Petrophysics program for the University of Tulsa in Venezuela. This phase consists of teaching the subsurface concepts and completing 3 petrophysical field characterizations. The project builds the static model from geology, geophysics, and core to log integration. Sufficient rock types were determined to model the water saturation and permeability within the 3D model. Fluid properties were added and the model was then up-scaled. Scoping reservoir simulations were run on each project. All projects and examinations during this phase were accepted by TU and all students were admitted for the last phase of the masters program. PDVSA was very impressed with the projects and the results, more than a billion barrels of recoverable oil was added and many re-completions were suggested. PDVSA decided to continue the 45 week program and will add 2 to 3 mini 16 week subsurface integration programs as well.
PEMEX
I assisted in the petrophysical portion of the 16 week subsurface integration program on six projects in Villahermosa. The results were very well received and 8 projects were added this year.
ConocoPhillips
Due to the results of the Dakota Study I did last year for Burlington, ConocoPhillips asked me to do reservoir characterizations on the Mesa Verde and Lewis formations. These projects are in the final stages of completion. All algorithm development is finished and data normalization is nearing completion.
2004-2006 Chevron, Next,Bp,Burlington Houston, Texas
President of Petrophysical Technologies
Field studies for Chevron in the divided zone between Kuwait and Saudi. With core as input, edited, calibrated, and processed well logs for input into static and dynamic models. Cross-section and parameter mapping capability of Geolog was used to identify anomalous wells and to help in the normalization process.
Completed 14 Well study for the Humma Field, Completed 240 Well study for the Mastrichtian Formation above the Wafra Field, Completed 30 Well study for the South Fuwaris Field for Chevron.
Taught Integrated Petrophysics IP School for Next in Venezuela (Maturin and Maracaibo). Helped with field study deep water Gulf of Mexico, Trinidad, and offshore Norway.
Interpreted 3 exploration wells for bp in McKenzie Delta, Canada
Completed San Juan Basin study of the Dakota Formation for Burlington.
Completed petrophysical study for Columbia
Working on 6 field studies in Mexico
Teaching Integrated Petrophysics to Schlumberger and others via Next
2002-2004 bp Kuwait City, Kuwait
Petrophysical Advisor for the Kuwait Oil Company
Petrophysical team leader responsible for over 15,000,000,000 barrels of reserves. Tasks include well planning, net pay assessment, property modeling, core analysis and the database management for both Openworks and Geolog databases.
Added thin bed technology to improve volumetric and model performance
Incorporated thin bed and bed boundary corrections with Crystal Ball interpretation of all reservoirs in North Kuwait
Developed Coates Timur perm approach with non-NMR data and matched to PLT results
1997 2002 Amoco/BPAmoco/bp Cairo, Egypt
Senior Petrophysicist for Egypt Gas Business Unit
Well planning, wireline operations, Landmark log database, well interpretations, net pay assessment, property modeling, core analysis, PVT analysis, and mentoring of government and national staff
Increased Ha'py reserves from 989 BCF to 1.96 TCF by developing a unique interpretation method which allowed Amoco/bp to double the gas sales agreement.
Completed Reservoir Characterizations for Ha'py, Seth and Akhen Fields as part of the Nile Delta Appraisal Team.
Member of four man Appraisal team rated Best in Class by external bp Front End Loading audit by IPA.
Provided production profiles for the North Alex LNG project (12 gas fields with over 20 TCF gas in place).
1995 1997 Amoco Research Center Tulsa, Oklahoma
Petrophyics coordinator, lecturer, mentor, and coach
Instructor, advisor and mentor for the Amoco Petrophysics program
With the help of the geological and engineering coordinator, we guided the teaching of data integration by problem solving actual problematic reservoirs. The results were complete documentation of 42 reservoir characterizations from core data through scoping reservoir simulation. Agreed value added by the program was in excess of $42,000,000. This Petrophysical program has since been purchased by Next, a consortium composed of several universities and Schlumberger.
Reservoir studies include fields from the following: Mancos, San Juan Basin, Gulf of Mexico, Mexico, Canada, Venezuela, Columbia, Onshore Netherlands and the North Sea.
