|Twenty-six years experience in North Sea, Middle East, Gulf of Mexico, and onshore U.S.A. operations , primarily with a major international oil company in petroleum reservoir engineering and reservoir management; economic evaluations of projects, property trades, and asset sales; corporate planning and world oil reserve estimates.
4/1999 to Present
| Advisor to Society Bankhouse Global, Boston, regarding acquisition of equity positions in upstream oil and gas ventures.
7/1998 to Present
| Partner with geological consultant and noted author, Dr. Colin Campbell
Ongoing development of conventional oil reserve estimates for the world. Gave presentations on the subject to: (1) the Independent Association of Drilling Contractors (IADC) at their annual March 1999 meeting in Amsterdam, (2) a joint conference between the Centre for Global Energy Studies and the Oil & Gas Journal in September, 1999 in Houston Texas, (3) the Canadian Nuclear Society, November, 1999, Ottawa, (4) institutional investors in Montreal, May 2000, Montreal, (5) James Baker World Energy Conference, May 2000, Rice University, Houston, Texas, and (6) Hawaii State Energy Symposium, November 2000, Honolulu.

|Malkewicz Hueni Associates, of Golden, Colorado
Performed tax studies and technical studies for the reservoir management and depletion planning of the giant Jay Field (tertiary nitrogen WAG flood), onshore Florida for Burlington Resources and Exxon Company U.S.A.
5/1990 to 6/1997
|Exxon Company, U.S.A., New Orleans Producing Organization as a Senior Reservoir Engineer.
Leader/coordinator of a $2 million engineering, geologic, research team to revitalize a mature, major (720 million barrels oil in place) oil field miscible water-alternating-gas flood project, for the carbonate reservoir Jay Field onshore Florida. Team accomplishments: (1) increased remaining reserve outlook 225% (+60 million barrels), (2) increased production to 4-year high, (3) extended economic life of the field by fifteen years, (4) renegotiated nitrogen (solvent) purchase and electrical power contracts for $3.5 million per year savings, (5) increased water injection by 40% to 235 thousand barrels per day and solvent injection by 40% to 90 million cubic feet per day, (6) developed state-of-the art 13.8 million cell stratigraphic geologic model for flood management and input to a new fine-grid 122 thousand block reservoir model under construction, (7) developed fluid geochemistry methodology for determining in situ nitrogen utility, and (8) developed full life economic field model including grass-roots operating expense model and volumes forecasts for planning purposes.
While on the $1.5 billion Mobile Bay Project a deep, sour gas development in the coastal waters off Alabama, I assisted the successful unitization of the Bon Secour Bay field, providing testimony at technical hearings with state regulators. Also, I provided technical evaluations to a successful property trade which consolidated Exxon's interests while improving profitability and project reserves. I also lead the planning for phase-in to operations at production start-up.
I also evaluated South Florida fields to establish sale value. These fields were subsequently sold.
