Summary

Senior Reservoir Engineer with expertise in unconventional gas reservoirs. Recognized for developing

solutions for rate-transient analysis in tight gas and shale gas reservoirs. Strengths include oral and written

communication skills, ability to use advanced mathematics to solve technical problems, dexterity to quickly

write spreadsheet code to implement engineering solutions. Abundant experience with single-well numerical

simulation in coalbed methane and shale gas reservoirs. Doctoral dissertation about stochastic reservoir data

integration. Experience in both the E&P and service sector.

U.S. Patent 7,577,527 “Bayesian Production Analysis Technique for Multistage Fractured Wells.”

Experience

Schlumberger 2004-Present

Company Award: Schlumberger Patent Award, September 18, 2008, Houston, TX

Senior Reservoir Engineer, RTC, Dallas, TX, 2008-Present

• Recognized with 2008 Schlumberger Patent Award for presenting innovative probabilistic solution in

rate-transient analysis of multistage hydraulically fractured vertical wells in tight gas reservoirs.

• Working closely with the R&D group, recognized for ability to develop effective semi-analytic type-

curve production analysis tool for horizontal shale gas wells. The tool was eventually implemented

in Schlumberger’s internal software (Advanta) currently used by our consulting services engineers.

• Supervised a group of three summer interns in a data migration project. Coordinated efforts with

management of new merger core analysis company ( TerraTek) to seamlessly transfer pertinent data

to our database.

• Hands-on experience with commercial software, e.g. ECLIPSE, Kappa (Saphir, Topaze)

Reservoir Engineer, DCS, Denver, CO, 2004-2008

• Exceeded expectations with development of probabilistic rate transient analysis workflow for the

production analysis of multistage hydraulically fractured wells in tight gas reservoirs.

• Recognized for assessing market needs and receiving positive feedback from consulting clients and

in peer review.

• Published technical paper to advertise the technical value of our probabilistic production analysis

workflow (SPE 107356).

• Received offer to sell the rights to use the probabilistic production analysis workflow for multistage

hydraulically fractured wells from Shell Exploration & Production Company . Schlumberger

declined the offer.

• Awarded U.S. patent No. 7,577,527 titled: “Bayesian Production Analysis Technique for Multistage

Fractured Wells”

• Promoted to Senior Reservoir Engineer and transferred to Regional Technology Center

(Unconventional Reservoirs) in Dallas, TX on April 1, 2008.
