The Green River Basin in the SW Wyoming is responsible for all production within Lincoln, Sublette, Sweetwater, and Uinta Counties in Wyoming. This study focuses on peculiar features in the Lincoln County, we call them FLTs (funny looking things), observed in the seismic data associated with the Triassic/Jurassic deposition in the Moxa Arch. The acquisition and processing errors cannot explain these features, which led us to look for a geologic explanation. Well to seismic ties on three wells surrounding the seismic survey indicated that the observed FLTs on seismic correspond to the Jurassic aged Nugget Sandstone formation. Based on the seismic inversion and the petrophysical model, we concluded that the lithology distribution is comprised of dunal and inter-dunal deposits.
