3. Geology of Green River Basin #10 Prospect
Geology of the Green River Basin #10 Prospect Area Bridger Lake, Lucky Draw and the Henry fields all produce oil and gas from sandstone reservoirs of fluvial point bar or crevasse splay origins of the lower Daketa Formation and were deposited parallel to the structural strike of the southern Moxa Arch. The reservoir sands are not laterally extensive, and not evenly distributed along the axian trend of the Moxa arch, but tend to occupy a flank position on the eastern, asymmetric limb of the north-south trending anticlinorium. The location of these fields can be explained based on the depositional, structural, diagenetic, hydrodynamic and thermal histories of the Lower Dakota Formation. These fields serve as the basis of modeling for the Green River Basin #10 Prospect. Collectively, these fields have produced BCF of gas, and MMBO. The Green River Basin #10 Prospect is a stratigraphic mirror image of the Luckey Ditch and Henry Fields, and was defined by seismic data, well data, production data, and surface geological data. this prospect has two objective reservoirs: the Frontier, and the Lower Dakota Formations. Trapping mechanisms of the Green River Basin #10 Prospect are both structural and stratigraphic. Partnership seismic lines show a low amplitude fold in the prospect location which is bounded on the east and west sides by normal faults with less than 200' of throw. Stratigraphic pinch outs limit extensive lateral reservoir development and may be both depositional or diagenetic as suggested by hints of convergent reflectors (on lap and down lap) and subtle changes in signal amplitudes within the reflective boundaries of the Dakota formation. Drilling depth to the Lower Dakota is about 14,500 feet. Estimated Reserves To estimate calculated reserves, a Dakota form line net reservoir map was constructed by integration of structural contours from the Top Dakota Structural map and net sand thicknesses of from Luckey Ditch, Bridger and Henry Fields. Areal dimensions of the contours range from 11,563 acres at the zero thickness contour to 780 acres at the 50' contour: The 30' contour is used as the median contour for most likely areal dimension. Estimated recoverable rels of oil (MMBO). Risked recoverable reserves are 73 Bcf, and MMBO. A geologic risk factor of 57% is assessed based on the ratio of the number of dry holes to producing wells drilled south of the Church Buttes Field, between Ranges 112 to 114 West, and Townships 12 to 16 North.

7. Frontier-Mowry Isopach
Structural growth is clearly demonstrated by stratigraphic thinning in the Frontier-Mowry interval along the crest of the southern Moxa Arch based on correlations of well data in the Lucky Ditch and Henry Fields (Figure 3). Stratigraphic thinning is expected at the Green River Basin #10 prospect location.

14. Paleo-drainage of Green River Basin #10
The location of paleo-depositional channels and drainage patterns along the steeper limbs of the southern Moxa Arch are critical to accumulation of economic deposits of hydrocarbons.
Figures 7 and 8 depict present drainage channels which flow northward from the Uinta Mountains into the Lucky Ditch and Henry Fields, and the Green River Basin #10 prospect area. It is possible that these glacial channels may have mimicked the location of Cretaceous paleo-drainage patterns.

Figures 11 and 12 are critical well logs: the 5-32 Wadsworth (D-1 sands are missing, but the D sands were wet, tight with some gas shows.
The Wadsworth Fee well lies down dip from Green River Basin #10, and has good porosity,but wet with oil shows (core description) in the D-1 Sand. This well was not tested.
