Summary

Reservoir evaluation and reserve analysis expertise of conventional and unconventional reservoirs.

Most recent experience includes reservoir modeling the Haynesville shale to history match pressure-

dependent formation properties and determine a better way to produce wells to maximize EUR.

Experience

Expert witness

KCS Energy, Inc. 1998 - 2001

Area Manager / Technical Team Leader, Wyoming /Montana properties.

Evaluated reserves for all Wyoming and Montana assets.

Prepared workover programs and supervised their execution.

Implement measures to maximize production and lower operating expenses ~ 30%

Supervised technical team of 7 geologists and engineers.

Presentations to senior management

Mobil Oil Corporation 1985-1992

Reservoir Engineer positions held in Denver, CO and Bakersfield, CA. Experience in Alaska North

Slope and Cook Inlet fields and various California properties.

Created a specialized cash flow program for Prudhoe Bay to quickly evaluate proposed

expansion projects. Program was used by Mobil management in arbitration.

Assessed P1-P3 reserves for Pt. Thomson, a 3-TCF Alaska North Slope property.

Identified 13 MMBO of P1-P3 reserves for a Cook Inlet property which initiated

a $16 MM drilling program. The first well had an initial production of 3600 BOPD.

Team leader for a $13 million heavy-oil development project.

Performed heavy oil, cyclic steam reservoir simulation studies and booked 10 MMBO.

Initiated routine and special core analysis for reservoir description and reserve estimates.

Recommended infill development on a property that increased production 900 BOPD.

Prepared project budgets and presented proposals to management.

Assessed California property values for divestiture using cash flows.

Operations Engineer position held in Ada, OK. Experience in primary oil, gas, and waterflood

operations.

Initiated projects related to injection and production improvement in 300 well, 100 MBW,

. + 4000 bopd waterflood. Performed injection balancing projects.

Specified and supervised acid and fracture stimulation programs.

Prepared well procedures for workovers, re-entries, and recompletions.

Performed lift optimizations on pumping units and submersible pumps.

Created well database program to monitor well tests, fluid levels, and equipment profiles.

Designed and analyzed pressure transient tests.

Material balance reserve studies..

Sized and installed gas compressors.

Attended 15 company sponsored industrial schools for professional development.

Western Geophysical Summers 1979-81

Marine seismic crew, Gulf of Mexico.

Education

Ph.D. Mechanical Engineering Texas A&M University 1999

M.S. Petroleum Engineering Texas A&M University 1984

B.S. Petroleum Engineering Louisiana Tech University 1982

Additional Skills and Knowledge

Ph.D. research led to extensive knowledge of metal behavior (e.g. elasticity, plasticity,

fracture mechanics, failure analysis, and nondestructive evaluation).

M.S. research involved two-phase flow in pipelines.

Software

PMTx, PhdWIN, ARIES, PEEP, Pfeffer, Rockworks, other numerical simulators,

RTA, and I have written many specialized petroleum engineering applications in VBA for Excel.
