Coal Committee

 

William A. Ambrose, P.G. is currently Chair of the EMD Coal Committee, Co-Vice Chair of the AAPG Astrogeology Committee, and is an EMD Past President (2007-2008). He is a Research Scientist at the Bureau of Economic Geology of the University of Texas at Austin, Texas.

His interests include clastic sedimentology, stratigraphy, unconventional energy resources, and planetary geology. Ambrose’s earliest projects (1984 through 1986) were with the Research Planning Institute, involving subsurface mapping of Tertiary formations in the Texas Gulf Coast, where he constructed regional depositional models for exploration.

Ambrose joined the Bureau of Economic Geology in 1987 and was involved in a variety of Texas oil and gas reservoir characterization projects, as well as evaluating brine-disposal zones from co-production of methane and brine from geothermal and geopressured reservoirs in Frio Formation in the Texas Gulf Coast.

In 1988, his research interests took a new direction when he began evaluating the coalbed methane potential of major Rocky Mountain basins, with emphasis on the San Juan Basin. After 1991, he was involved in several international oil and gas studies, beginning with the LL-652 Area in Lake Maracaibo, Venezuela. Since then Ambrose has been involved in six other oil and gas projects in Venezuela, as well as a study of Permian gas reservoirs in the Cooper Basin, Australia

From 2000 to 2005, Ambrose was involved in several regional analyses on the geological framework and potential development of Tertiary basins in the Gulf Coast of Mexico, and more recently in the BEG STARR (State of Texas Oil and Gas Resource Recovery) reservoir characterization project in East Texas field.

More recently, he has been conducting subsurface analyses of depositional systems, sedimentary modeling, and production trend analysis of major Texas oil and gas plays. Ambrose also has been evaluating the geologic factors controlling the occurrence and producibility of coalbed methane in the Western United States, as well as evaluations of the geologic controls on saline aquifers for CO2 sequestration in the Gulf Coast.

Over the years, Ambrose has received numerous honors and awards, among them are:

His most recent and relevant publications include:

Ambrose has co-chaired numerous EMD-sponsored technical sessions at meetings of professional societies and has given presentations on topics related to coal and unconventional energy sources at AAPG and PTTC workshops. He received his Bachelor’s and Master’s degrees in geology from The University of Texas at Austin in 1979 and 1983, respectively. In addition to the AAPG, he is a member of the Houston Geological Society and SEPM.
