Scotts Bluff Trend is a group of 10 oil fields that produce from the Cretaceous J Sandstone. Production was previously thought to be aligned along this trend due to structural influence.;For this study well logs were utilized in analyzing structural and stratigraphic elements, as well as hydrocarbon predictability. The Scotts Bluff Trend appears to sit upon a residual structural high. A comprehensive look reveals that stratigraphic influence is superimposed on the structural high.;J1 Sandstone reservoirs were mapped assuming a NW--SE depositional trend. Deposition was in a shallow-marine bar environment. Central-bar, bar-margin and interbar facies are recognized which interfinger laterally into the surrounding trapping siltstone.;A predictor of hydrocarbons was attempted by way of resistivity mapping. Although unsuccessful, use of these resistivity maps in conjunction with structural and stratigraphic maps has led to the recognition of at least seven prospects.
