Reservoir Engineer Field Studies Group

Transferred to Field Studies Group 2/2007. Duties include engineering water floods and CO2 floods for

the company. Primary work is done in Excel and Petra while economic evaluations are done using

ARIES. Further detail would be unethical due to the proprietary nature of the projects. Also designed

programs in Excel for wellhead allocation of production, wellbore diagrams, statistical distribution,

stochastic modeling of wildcat prospects, material balance, and others.

District Reservoir Engineer TX Gulf, Louisiana, E. TX

Duties include all basic duties of a reservoir engineer, such as economic evaluation of all properties in the

(SPCC Plans, LLC) for more than 8,000 wells in Oklahoma, Texas, New Mexico, Kansas, Arkansas, and

Louisiana. See http://www.spillplans.com . SPCC Plans, LLC was sold to Campbell & Assoc. - 5/2008.

Other specialties related to reservoir engineering include coalbed methane extraction, reservoir/formation

evaluation, pressure transient analysis, Nodal Analysis, production optimization, exploitation of assets,

evaluation of enhanced recovery projects, acquisition and divestiture analysis, asset management, and

environmental compliance.
