...Don E. Lawson; Jordan R. Smith ABSTRACT The Big Horn basin is in northwestern Wyoming in the central Rocky Mountain province. Near the close of Desmoinesian time, regional uplift on the west and north elevated the Tensleep Sandstone of the Big Horn basin above sea-level. Broad, low-relief...

... Limestone is a regional aquifer that provides the water drive for the Tensleep reservoir. The Chugwater and Permian Goose Egg Formations (a mixture of shale, siltstone with some sandstone) serve as the primary seal for the Pennsylvanian Tensleep reservoir (Figure  2b ). The Tensleep Formation...

...Janell D. Edman; Ronald C. Surdam Petrographic and geochemical data from cores in the Wyoming Overthrust belt are used to integrate thermal maturation of the Phosphoria with timing of cementation and porosity development in the Tensleep and Madison. Vitrinite reflectance studies from the Phosphoria...

... of petroleum in the water, or by a combination of these actions. Oxidation-reduction reactions between artesian water and petroleum can also explain the fact that API gravity, per cent light gasoline fraction, and sulphur content of Tensleep oil display regional variation patterns which closely conform...

...John R. Fanshawe ABSTRACT Phosphoria and Tensleep traps in the Big Horn basin are contrasted as to those controlled by strong artesian water flow, and others where subsurface water movement is at a minimum. Fresh waters cause changes in the nature of the entrapped petroleum as a result of lower...

... process. This omission is a critical mistake. We have documented a complex heterogeneous fracture development within the eolian Tensleep Sandstone in Wyoming, which arguably is one of the least complex reservoir facies. Fractures develop at four scales of observation: lamina-bound, facies-bound, sequence...

... to present both the variability and the common themes as conceptual models for predicting and exploiting fractured Tensleep reservoirs. Tensleep-equivalent strata crop out 25 mi (40 km) south of Laramie, Wyoming, along Sand Creek in southeastern Wyoming (Figure 3 ). Called the Casper Sandstone, the strata...

... ). Crosscutting relationships indicate that deformation bands were among the first structures to form in the Tensleep sandstones. They are not systematically oriented or distributed across the anticlines, suggesting that they did not form within a regional, well-ordered stress system. Figure 4. Box-work...

... on Figure 1 . The regionally widespread Tensleep, which may be several hundred feet thick, is transitional with varicolored shales, carbonate rocks, and anhydrites of the underlying Amsden. It is separated from the overlying Phosphoria by a significant erosional unconformity. At Oregon Basin the Tensleep...

The 1.0-bounding surfaces truncate lower-rank (2.0, 3.0, and 0.1) surfaces and eolian cross strata. Tensleep outcrops along the west flank of the Bighorn Mountains...
