Experience Narrative:

Dr. Odegard began to work in oil and gas exploration in 1983 at Sohio Petroleum Company where he was supervisor of the Seismic Analysis Group.  He developed a full wave synthetic seismogram program for AVO studies.  It was first used on a 3 component AVO project in the Lisburne field on the North Slope where the project was able to determine the location of the high porosity dolomites.  This was instrumental in further development of the field.  The program became a standard for Sohio and its parent company British Petroleum.  Dr. Odegard applied it to problems in the Anadarko Basin, Rocky Mountain Thrust, Gulf of Mexico, and finally Qatar where he helped to find a multi-TCF gas field.

He joined Unocal in 1988 where he was supervisor of the Lito-Stratigraphic Workstation project, the Special Seismic Processing Group, and then developed the project “Exploration in Difficult Data Areas”.  Results of these projects were used in Indonesia, Alaska, Syria, and Belize.  He was transferred to the exploration group for Southern Africa and Latin America.  There he was responsible for doing the geophysical analysis for most of the farm-out proposals received by Unocal.  He also worked on the initial bid round for Namibia, where he interpreted the northern third of the offshore area.  This was for a consortium consisting of Unocal, Sun Oil, OMV and Deminex.  He developed the group’s number one prospect, “Khunene” in block 1711 Namibia.  After this he worked with the Conoco/Unocal group that drilled three wells in Angola’s Block 6, including the famous “Falcao-1” well.  He was also the principal geophysicist in the US for exploration of offshore Senegal.  In this position he sited the Wolof-1 and Diola-1 wells.

Dr. Odegard was transferred to Sugar Land where he was supervisor of the potential fields group.  This group was in on the initial development of almost all new plays at Unocal.  As part of this group, and because of his expertise in seismic interpretation and processing, he was also a functional part of several exploration teams.  This included onshore Bangladesh (several large gas fields developed and discovered), San Jorge Basin Argentina, Sub-Andean play area, deep water Brunai, and offshore Vietnam (oil and gas field discovered).  During this time he also did research on the emerging field of gravity gradiometry, sometimes called the Full Tensor Gradient, and gave several invited papers.  He applied gradiometry to structural salt modeling in the Gulf of Mexico over the Flex-Trend.

After leaving Unocal, Dr. Odegard became Vice President and manger of GETECH, Inc., which is a subsidiary of GETECH, Ltd. in Leeds, UK.  He developed the business from a two man sales office into a six person plus five associated consultants office doing integrated exploration projects and data sales.  He personally worked with Bill Dickson on the SAMBA project over the South Atlantic basins, which has been licensed to over 14 oil companies and the SEAMAGIC project over Southeast Asia.  He also worked with Robert Hickman and Norman Kent in the development of the WAGGS project for the Trenton-Black River hydrothermal dolomite and other plays over the Appalachian Basin, which has been licensed to over 7 companies.  He also developed the NAMBA project over the North Atlantic basins.  As part of this he produced modules over Morocco and Northwest Africa, Northeast North America and Greenland, and the Caribbean, with high resolution modules over Trinidad (for the 2004 bid round), and Suriname and the Guyana Basin.  These projects involved integration of all generally available geological, geophysical, well and satellite data into regional to sub-basinal exploration packages, which have been licensed by several companies.  The projects are particularly useful in initial play development the analysis of farm-out proposals.  As a result of the success of all these projects he also worked on proprietary projects for companies over Morocco, offshore Angola, the West Siberian Basin, the Pre-Caspian Basin (two), the Banda Sea area, Suriname/Guyana, Libya/Tunisia/Algeria, east China, Campeche and Vera Cruz Mexico, and north Louisiana.  This work has carried over to his own consulting company, Grizzly Geosciences, Inc., after the reorganization of GETECH.

Dr. Odegard has also held positions as Assistant Researcher and Professor at the University of Hawaii, Director of the Geology and Geophysics Research Program for the U.S. Navy, Associate Professor of Physics and Geology at New Mexico State University, and Principal Scientist at the Basalt Waste Isolation Project at Richland, Washington.  He has over 100 scientific publications.

His education includes a Ph.D. from the University of Hawaii in Geology and Geophysics, a M.S. from Oregon State University in Physics with an Option in Geophysics, and joint B.A.’s is Physics and Mathematics from the University of Montana.  He also has course work and has applied Risk and Probabilistic Financial analysis to plays and prospects.

Because of the work described above, Dr. Odegard has a unique general and specific knowledge of the varied geologies over many areas of the world.  This gives him the ability to quickly analyze areas for the suitability for hydrocarbon exploration and development.

Recent Activity:

Consulted for a major international oil company in an assessment of the hydrocarbon potential of their blocks in Suriname and the Guyana Basin.  Completed an integrated GIS project for both regional and prospect analysis over that area.  This included integrated modeling using gravity, magnetic, seismic, well log and geological data.  Work also included data integration and depth to basement inversion.  Consulting for a major chemical company in the evaluation of sites for construction of plants in Mexico and China.  Evaluated 2 and 3-D seismic, well and geological data.  Constructed GIS projects and integrated models over proposed sites.

Screening prospects over areas in the Texas Gulf Coast, Williston Basin, Big Horn Basin, New York, New Mexico, Morocco, New Zealand and Bulgaria for an investment group in Denver, Colorado.  This involves an analysis of the economic potential using risk and economic analysis, as well as geological and geophysical analysis and interpretation.

Started the Madison Valley Energy Company to invest in a percentage of a 7,700 acre lease in Kenedy County, south Texas.  Wells will be drilled to the lower Frio and Vicksberg formations.  Estimated risked reserves are 200 BCFG.  The operator is a large Australian company.
