Experience: Reservoir engineer with eight years of experience with a large independent and an oil and gas finance company. Highly experienced in reservoir engineering in the west Texas, Texas Gulf coast, and Rocky Mountains areas. Experienced in detailed reservoir engineering analysis including material balance and simulation. Production engineering experience includes plant process evaluation to maximize NGL recovery and profitability. Recent experience includes advising, structuring, and executing risk management strategies to finance debt and equity transactions. Special computer program knowledge includes SAM, @Risk, Crystal Ball, VIP, Eclipse and TERAS economics software.

Structured risk management strategies to finance debt and equity transactions. Managed a technical staff responsible for evaluating assets including quantifying uncertainties through probabilistic risk simulation. Structured 17 transactions totaling over $500 million.

Evaluated reserves, forecasted production, identified acquisition candidates, and evaluated farm-in agreements. Completed field study of east Texas Cotton Valley sands resulting in large increases in field production rates through infill drilling. Performed a compositional simulation of a retrograde gas condensate reservoir. Evaluated the technical and economic feasibility of continued gas cycling, methane and nitrogen repressuring, alternate injection patterns, and blowdown scenarios.

Identified recompletion opportunities and wrote procedures; designed acid and fracture treatments; designed well test procedures; evaluated reserves, and conducted economic analyses in the Rocky Mountain region. Integrated reservoir, production, and process engineering with economic analysis to optimize gas plant operation. Evaluated plant process changes on NGL recoveries using HYSIM. Simulated multistage compression of unprocessed gas to predict changes in composition of discharge gas for renegotiating gas sales contracts.

Conducted a study of an overpressured, south Texas gas field. Built a computer model to simulate the gas plant flow process. Assisted in implementing plant process improvements. Performed surface equipment design, pipeline sizing, and permitting for new south Texas wells. Evaluated reserves for Permian Basin wells. Evaluated and implemented CO2 flood pilot in west Texas.
