1992 to 1996   Maxim Technologies, Inc., (Huntingdon, Chen-Northern)

• Conducted numerous Phase I ESAs of oil and gas, commercial, light industrial and residential properties including review of NPDES permits, SPCC Plans, compliance issues and norm surveys.     
• Managed Phase II ESAs including two site investigations for Conoco, Inc. for the releases of refined petroleum products from pipelines. The projects involved waste, groundwater, soil and air sampling and analyses, determination of contamination extent, recommended improvements in chemical handling procedures, assessment of natural attenuation and evaluation of applicable remediation alternatives.
• Served as the interim environmental coordinator for Black Thunder Mine, Thunder Basin Coal Company, a subsidiary of ARCO, Inc.  Responsibilities included tracking, collection, storage, and shipment for disposal of hazardous waste, used oil and waste grease generated at the mine using RCRA and DOT guidelines.

1980 to 1992 Oryx Energy Company, (Previously Sun Company, Inc.)

• Developed five Morrow and Atoka deep gas discoveries utilizing pressure transient analysis, material balance P/Z and volumetrics. This resulted in the drilling of 10 wells at 1.5 million dollars each; eight were producers.
• Testified as an expert witness at state hearings. Served on technical committees for three proposed secondary units.
• Supervised four ressim engineers while concurrently performing simulation projects.  Conducted one-on-one training of new simulation engineers as well as coordination and support of company wide simulation workstation training.
• Performed a reservoir study of a 10 million dollar gas cycling project in the Dakota formation of Wyoming using a compositional simulator in support of technical committee objectives.
• Predicted the waterflood performance of eight proposed waterflood projects in  Oklahoma, Texas and offshore using Nolen's VIP, a black oil simulator.
• Simulated steam injection for heavy oil in California using SSI's THERM, a thermal model.  Doubled recovery by recommending a change from cyclic to continuous steam injection.
• Monitored existing waterfloods recommending recompletions, pattern changes and injection rates as needed.  Evaluated injection performance using pressure fall-off testing and injection profiles.
• Prepared feasibility studies to implement secondary recovery projects or infill drill existing projects.
• Coordinated development of two new waterfloods, including pattern optimization and the drilling of 30 secondary recovery wells.
