Lake Level Controlled SedimentologicalHeterogenity of Oil Shale, Upper Green RiverFormation, Eastern Uinta Basin, Utah

摘要

The Green River Formation comprises the world's largestdeposit of oil-shale and has enormous potential to meetglobal energy requirements, yet a detailed sedimentologicalcharacterization of these lacustrine oil-shale deposits in thesubsurface is lacking. This study analyzed ~300 m of corescorrelated to gamma and density logs in well P4 in the lower tomiddle Eocene (49.5-48.0 Ma), upper Green River Formationof the eastern Uinta Basin, Uintah County, Utah. In well P4,three distinct facies associations are identified that representthree phases of deposition linked to hydrologic evolution of theLake Uinta.
