dc.description.abstractA stratigraphic correlation was constructed for the Eocene Green River Formation in the area of the southeastern Uinta basin, Utah that integrated centimeter-to-decimeter scale outcrop and core measurements with 12 well logs. Green River Formation strata from the Uteland Butte tongue to the Mahogany Marker were examined. This correlation connects existing outcrop and subsurface studies and provides facies-to-log calibration for the characteristically unusual log responses of Green River Formation strata. The correlation utilized nine markers that were consistently present in the study area and which tie into existing studies (Hogan, 2015). Log calibration of lacustrine facies has traditionally been difficult due to facies and stratigraphic complexities. This study utilizes gamma ray assay measurements of described outcrop as well as gamma ray, bulk density, and neutron porosity of described cores to provide a general calibration of log response to facies association. This identified five groupings of calibrated facies associations: FA1 - Fluvial sandstones, FA2/FA6 - Floodplain and littoral mudstones, FA3 - Deltaic deposits, FA4/FA5 - Carbonate deposits, and FA7 - Oil shale. These calibrations are useful in determining facies distribution and depositional environment where the only (or predominant) data source is well logs.
