Major Projects
Early in his career, Pence evaluated the technical and economic feasibility of primary field development projects, secondary and tertiary recovery projects, and production optimization through recompletion and stimulation operations in the Rocky Mountain region of the U.S. He also worked with cyclic and continuous team injection projects in the Midway Sunset field of California.

Since joining D&M, Pence has evaluated major gas fields in emerging provinces worldwide. Pence has accumulated significant experience in evaluating deepwater depositional systems and deepwater development projects. His experience working pre-appraisal and pre-development projects has aided clients in quantifying uncertainties and helping to guide appraisal and development programs. He has specialized in evaluating fully developed oil and gas fields under primary and secondary recovery.

Pence has served as reservoir engineer and project manager for the certification of gas fields in support of LNG developments, lender due diligence for project finance, gas purchase and supply agreements, and acquisition projects as well as the annual reserves and resources evaluations required for regulatory filings.

Pence’s experience prior to joining D&M included reservoir simulation studies of the application of horizontal wellbores to water-coning problems, low-permeability gas reservoirs, and reserves-recovery acceleration. He also conducted field studies for Oryx throughout the U.S. Gulf Coast, primarily as a member of an integrated work team studying fields where the use of 3–D seismic interpretation was utilized to exploit existing fields and the need for a comprehensive, multi-discipline approach was required.
