Career Summary

Accomplished Senior Geophysicist with extensive experience in acquisition, processing, interpretation and reservoir characterization. Experience ranges from R&D through Seismic Data Processing to Prospect Generation, Operations (drilling well decision making) and to Field (Prospect) Development and Study.

Experienced in all Gulf of Mexico plays including deep water and Sub Salt. Onshore experience in the Miocene, Wilcox, Smackover and Cotton Valley plays. Caused the first shelf subsalt objective to be drilled in VM 356 by depth migrating TOS and BOS via ray traced map migration using the Sattleger ISPOO3 software.

Foreign experience includes field studies on two Miocene fields in Trinidad Off Shore, mapping the Bangladesh portion of the Bay of Bengal, and the study of four large fields in the onshore Sichuan Basin of China.

Domestic experience includes a South Louisiana Zone One exploration program in which I was solely responsible for acquisition design and implementation, processing and interpretation. I mapped several quads of Frio on 2d data along and across the Mexican border. I supervised a large group of Earth Scientists who digitally mapped the entire offshore GOM as a part of a regional project effort. I recently completed field studies of four Miocene fields in Lafourche Parish Louisiana on 50 sq miles of 3D and developed more than 40 drillable prospects. As a member of a development team I was the Operations Geophysicist with responsibility for two GOM fields under active development. In that role, I mapped and picked locations for wells in the HI A572 complex and MA 622 complex. Both were large, active fields with active drilling programs and exceptional velocity problems.

Supervised Data Processing and Regional Mapping and Projects Groups. Strong technical background, a proven planner, organizer, problem solver, and oil finder. At one time I supervised a group of15 professionals and 10 technologists in processing GOM marine seismic data. I was responsible for the training of new hire geophysicists in AMOCO’s methods and techniques of data processing, mapping and presenting to management.

Experienced 2-D and 3-D SMT KINGDOM and LandMark mapper. Also familiar with SURFER mapping and Kriging. Have extensive EarthPak experience with both digital and raster logs. Have correlated thousands of logs and used Paleo Control where available. Made hundreds of Geologic cross sections with annotations of Geology (cores, perfs,etc.), Production(monthly, cums, tests, etc.), and Paleo Environments.

Extensive experience in generating synthetics and tying Geology to seismic; time and phase balancing of 2D and 3D seismic grids, modeling seismic responses and calibrating seismic attributes to lithology and production. Experienced with impedance inversion and AVO inversion.

Experienced in reservoir productivity prediction, risk evaluation and estimation of risked return on investment. Developed MS ACCESS software for purpose of documenting prospects with graphic displays, and computations of net and gross risked and un-risked reserves and cash flows.

Current in technology: I am competent in the use and quality control of Time to Depth Conversion, AVO (direct hydrocarbon detection), Migration before and after Stack ( Subsurface Imaging), Reservoir Characterization, Complex Seismic Attributes and their application to Reservoir Characterization.

Expert in Velocity and Time to Depth Conversion Technology. Two Papers published. Have taught classes on time to depth conversion for AMOCO and for SIPES.

Experienced in R&D and Seismic data processing and quality control.

Experienced Corporate Trainer. Taught in-house courses and acted as a mentor for new hires.

Selected Accomplishments

. • Organized Geological and Geophysical data for a large land owner in South Louisiana and managed their data room. Data consists of 3 3D seismic surveys and nearly 300 wells with logs and well files. Tied in 20 Paleo Studies in area wide mapping of 20 producing sands. The field studies developed over 40 prospects on their data.

. • Mapped four fields in the onshore of China for a major independent. Tied 6000 km of seismic to 20+ synthetic traces and balanced phase, time, and amplitude at the line intersections. Made technical presentations to the Chinese National Oil Company and the Sichuan Petroleum Corporation. Negotiated the purchase of 6000 km of seismic data. Supervised data reprocessing for AVO attributes. Converted time to depth using my proprietary LinFaust technique.

. • Mapped a field in the offshore of Trinidad for a major independent. Integrated 8 wells and 6 horizons into a detailed field study. Used a proprietary Linearized Faust depth conversion method which had a significant effect on reserves computed.

. • Participated as an integrated team member to map HI-A573 field for a field study in a 6 block (54 sq mi) area characterized by large horizontal velocity gradients; used Sattleger software to map, depth convert, and model the prospects.

. • Served on an integrated exploitation team assigned to produce a field study of the Matagorda 623 field; produced field wide maps on 10 horizons, resulting in 13 new prospects. Used LINFAUST depth conversions which had a significant effect on the maps.

�.• Designed and wrote velocity analysis and reflection statics programs, and

Designed a velocity database which implemented company (AMOCO) wide. Moved that database to the work station environment and updated functionality for AMOCO.

. • Developed a simple and effective method of calibrating stacking velocities to check shot surveys, for use in time to depth conversion. The method has been applied world wide and is available as a technical service.

. • Supervised seismic data processing for lease sales in the Gulf of Mexico, and developed new processing flows that greatly improved results. Trained approximately 50 new geophysicists in both data processing and structural mapping.

. • Supervised Seismic Stratigraphy and regional mapping groups in the Gulf of Mexico using 15 interpreters. The initial regional mapping of salt and Sub Salt prospects in the Gulf of Mexico was completed as a project.

. • Successfully initiated and completed the first AMOCO Sub Salt play in the Gulf of Mexico including modeling, and map migrations. Used Johannes Satleger's ISP003 map migration program to successfully migrate and depth convert a sub salt time interpretation.

. • Planned, acquired, processed and mapped seismic in Zone I play - Louisiana Delta which resulted in subsequent acreage acquisition and a seismic discovery drilled. Designed and supervised data acquisition and processing to solve the severe noise and static problems peculiar to the Mississippi River Delta Zone I area.

. • Authored two US Patents on methods of acquiring 2-D and 3-D Seismic which allow Geophysicists to design data acquisition schemes that have robust static correction solutions.

. • Evaluated Sierra's RAYMAP and SIVA programs for use in Sub Salt and other velocity problem areas.

. • As operations geophysicist on a drilling wildcat, unmigrated and remigrated maps using updated velocities from the drilling well and the ISP003 map migration program. As a result, recommended an expensive well steering program to save the objective from being faulted out.

. • Conducted extensive "Advanced Velocity Analysis and Depth Conversion" training at Corporate Training Center biannually for 3 years.

. • Supervised the design and implementation of a Petrophysical Rock Properties data base and software that provided insight to interpreters evaluating Amplitudes and AVO throughout the Gulf of Mexico.

. • Participated in an evaluation of a research "depth migration before stack" software. As a result of the evaluation, extensive changes were made.

. • Developed a series of lectures and presentations to enhance technology training for managers and Exploration training for researchers.

. • Developed and implemented a Geoscience Data model appropriate for field studies using IBI Focus data base and report writing software. The Database was then used for upload to the workstations. Have since transferred this technology to MS ACCESS.

. • Designed and executed exhaustive field tests with the AMOCO research party, which lead to improved seismic quality in the Florida Panhandle.

. • Received several awards recognizing exceptional achievements.

• Interpreted a Wilcox prospect for a small Independent and depth converted with a strong velocity gradient that turned the direction of dip around in going from time to depth. The results created a prospect that was not visible on the seismic time map.

. • Designed, implemented and installed a corporate velocity data base and processing system for Amoco.

. • Presented papers on velocity, anisotropy and depth conversion at National OTC and SEG conventions.

. • Authored the first corporate velocity analysis program for AMOCO and coauthored the first corporate reflection statics program. Recommended changes to all AMOCO Seismic Data Processing Programs to assure fidelity of amplitude output.
