Petroleum Systems of Divergent Continental Margin Basins

Houston Marriott Westchase, Houston, Texas
December 4-7, 2005

Conference Program and Abstracts (pdf)

Are you exploring on the North Atlantic, Central Atlantic (including the Gulf of Mexico), South Atlantic, Australian, or East African margin, or any current or past setting that may be similar? Looking for analogs in syn-rift, rift-to-drift transition, or passive margin settings? Trying to understand the petroleum systems that make these settings the locations of giant hydrocarbon deposits? Petroleum systems, tectonics and thermal histories, basin analysis and modeling, sedimentation and sequence stratigraphy, and salt tectonics in these and other regions and tectonic settings will be addressed in one or more sessions in the GCSSEPM Foundation's 25th Annual Bob F. Perkins Research Conference, "Petroleum Systems of Divergent Continental Margin Basins." Currently, 52 abstracts have been accepted for oral presentation and 3 for poster-only presentation from 52 authors. More than half of these authors are non-U.S. based, residing in Canada, Norway, France, Brazil, Great Britain, and Scotland.

On behalf of the Program Advisory Committee Co-chairs and the Program Advisory Committee, we invite you to attend, learn, and participate in this conference.
