The objective of this effort is to reduce the technical risks and the economic uncertainty standing in the way of increased efficient industry development of the low-permeability (tight) gas resources of the Greater Green River Basin (GGRB) of Wyoming. The overall goal is to encourage development and utilization of the GGRB tight gas resources by industry. Two of the most prolific tight gas reservoirs in the Green River Basin, the Frontier and the Mesaverde, have been extensively developed in the Moxa Arch and Wamsutter Arch areas, respectively, using vertical wells and hydraulic fracture treatments. The deeper, overpressured areas of the basin have been much less developed due to uneconomic production rates. Yet, the Scotia Group 1993 study identified as much as 200 Tcf of deep Frontier and 50 Tcf of deep Mesaverde gas resource potential. Lower than normal reservoir permeability's/porosities and the lack of extensive natural fractures are attributed for the low productivities in previous drilled deep wells. The subject project is intended to reduce these technical risks by testing more effective hydraulic fracturing techniques in a vertical wellbore or to intersect significantly more natural fractures in a horizontal or deviated wellbore. The approach to the project consisted of three phases: Phase I Site Characterization, Phase II Vertical Characterization Well, and Phase III Horizontal Well. Phases I and II resulted in the drilling of the Stratos #1 well (S24-T22N-R107W) through the Second Frontier to a total depth of 16,250 ft. Reservoir characterization and production testing of the Frontier formation determined this location was not favorable for attempting an advanced hydraulic fracture treatment nor for attempting a horizontal lateral. Further site characterization work identified the preferred location and wellbore azimuth for attempting a horizontal lateral to intersect substantial natural fractures in the overpressured Frontier formation on the eastern flank of the Rock Springs Uplift. The blanket marine and lenticular fluvial reservoirs characteristic of the Second Frontier represent prime candidates for a demonstration project that would compare production improvements by drilling, completing and testing of vertical and horizontal, directionally-drilled, wells. Developing techniques to more effectively and economically improve exploitation efficiencies in the Second Frontier has potentially high rewards because this previously unattainable gas resource in the deep Frontier is so large.
