William A. Ambrose is a geologist specializing in sedimentology and reservoir characterization. He received a Master of Arts degree in geological sciences in 1983 from the University of Texas at Austin. Before joining the Bureau of Economic Geology in 1987, he was involved in regional subsurface studies
Of the Yegua and Vicksburg Formations and the Wilcox Group in the Texas Gulf Coast. Ambrose has worked on a variety of projects at the Bureau, including characterization of Frio fluvial and deltaic reservoirs in South Texas, co-production of gas and hot brine from Oligocene reservoirs in the Texas Gulf Coast, evaluation of coal bed methane reservoirs in Rocky Mountain basins, and reservoir characterization and basin analysis studies in Venezuela and Mexico. He is currently a co-principal investigator of the Bureau’s STARR (State of Texas Advanced Oil and Gas Resource Recovery) program, chair of the EMD Coal Committee, and co-vice chair of the AAPG Astrogeology Committee.
