1991-1997: CONSULTING GEOLOGIST
BP Exploration, Alaska, Anchorage, AK
• Wellsite consulting in Prudhoe Bay Field, North Slope, Alaska and on numerous high profile exploration wells including Yukon Gold and Sourdough, adjacent to ANWR and two Trailblazer wildcats in the NPRA. Since 1994, have been responsible for supervision and geo-steering on over 130 horizontal sidetracks, multi-laterals, conventional grass root wells, and coil-tubing sidetracks. Geo-steered record setting BPX, R-18b, completed for 10,000 BOPD.
