AREAS OF EXPERTISE

Reservoir Simulation Studies: Experience in reservoir simulation for field production optimization.  Various aspects include model design and construction, PVT analysis, and studying the well history and completion dynamics for full-field history matching.

• Al Roidhat Field, Yemen – using reservoir simulation flow models to study the potential primary and secondary ultimate recovery in 15° API heavy oil field.  The affects of drainage and acceleration from infill well development using various reservoir simulation scenarios were used to estimate reserves for the appropriate reserve categories for reporting to the Canadian Alberta Securities Exchange.
•  Kern River Field, California – history matching heavy oil field production from 1918 and cyclic steam injection starting in the 1960s for current field development.
• Torcaz Field, Colombia – studying various EOR mechanisms in a heavy oil field, including thermal In-Situ Combustion, thermal Cyclic Steam Injection, and Cyclic CO2.
• Catalina Field, Colombia – studying various EOR mechanisms in a light oil field, including enhancing the natural water drive and gas injection.
• Borde Mocho, Argentina – studying the development phase of the field for future waterflood development.
• Deer Island, Louisiana - studying the loss of reserves from water encroachment resulting from a wellbore blowout.
• Mobile Field 904 – studying the potential reserve recoveries under several reservoir model scenarios using limited PVT data on the 22,000 ft/19,000 psia Norphlet sand
• Lodi Field, San Joaguin, California – full-field history match of an active water-drive gas reservoir and the field optimization for development into a gas storage facility.
• Rotherwood field, Texas – model analysis of reserves and the evaluation of various Gas Storage development alternatives to optimize field economics and to improve the deliverability of gas production from the field and gas injection for storage.
• South Ellwood field, Offshore California - full-field optimization and field development study for reservoir exploitation.  Several case studies were performed to evaluate the effect of well-to-well interference, the drainage on existing wells caused by infill drilling, the accelerated production of reserves, and the field drainage that occurs from adding extended-reach wells.  Case studies also help field optimization by comparing the results of future performance from various development scenarios.
• Co-authored an SPE continuing education short-course, specifically on “Grid Construction” and “Preparing Well History” for reservoir simulation.

Traditional Reservoir Engineering Studies: Economic evaluation experience in fields and reservoirs throughout the world.

• South Louisiana field development - experience includes log analysis and volumetrics combined with recovery techniques for determining sweep-efficiencies in water-drive reservoirs to be used as analogy for determining future development and recovery.
• Mississippi waterfloods – experience includes analyzing waterflood response as a function of pore-volumes injected for modeling future performance and peak rates in fields undergoing active flooding.
• California cyclic steam floods – experience includes analyzing cyclic steam floods through the use of steam injection in horizontal and vertical wells in low oil-gravity reservoirs.
• Middle East field acquisitions – experience includes analyzing multi-layered reservoirs undergoing gas injection for field optimization and improving economics.
• Analysis of tight gas sands – experience includes analyzing thousands of tight gas wells throughout the San Juan Basin of New Mexico, the Piceance Basin of Colorado, and the Canyon sands of West Texas.
