“…During the Eocene, the third trend involved north-south compression that caused northward and southward thrusting on the flanks of east-west trending uplift (Gries, 1983 (Pyles, 2000;Hamzah, 2001). The Wind River Mountains and Rawlins uplift may have been active during the Maastrichtian (Steidtmann et al, 1986) and the Rock Springs uplift may have been active as early as the Campanian (Gries, 1983).…”

The Lewis Shale is an emerging natural gas exploration target in the Great Divide and Washakie basins, Wyoming. The purpose of this study is to estimate the volumes of gas-in-place in the Lewis Shale interval. This study employs a 3-D geologic model and uses this information to calculate gas-in-place volumes in sandstone lobes of the Lewis Shale. Cross sections were constructed across the study area prior to doing regional stratigraphic correlation. Using this technique, 12 sandstone lobes were interpreted. Different inferred paleocurrent directions were also interpreted using isopach maps. Deep-water sandstones of the Lewis Shale initially entered from the northwest and later from the northeast, southwest and east. A 3-D geologic model was built to mimic the subsurface geology of the Lewis Shale in the Great Divide and Washakie basins. Well log data, a 3-D geologic model, and
