Wind River Resources Corporation entered into an Exploration and Development Agreement and an Option Agreement with the Ute Indian Tribe of the Uintah and Ouray Reservation to cover the exploration of approximately thirty-one square miles of Tribal minerals for oil and gas. Wind River also obtained oil and gas leases from the State of Utah covering two additional square miles contiguous with the Tribal lands. These lands are located immediately to the south of the Flat Rock Field, largely in T15S-R20E. The structure on which the Flat Rock Field is developed appeared to cross onto some of the acreage covered by Wind River's agreements with the Ute Indian Tribe. In October of 1999, Wind River Resources, with the Ute Indian Tribe as partner, applied to the Department of Energy for a grant in the amount of $500,000 to be used toward the cost of a 3-D seismic survey to explore for oil and natural gas liquids on Tribal mineral lands. In May of 2000, Wind River was notified that its proposal had been selected for funding. Negotiations for the grant contract and work in support of a categorical exclusion from the requirements of NEPA for the conduct of the seismic survey were concluded during the summer of 2000. The contract was awarded and field work in support of the survey commenced in September of 2000. Field acquisition of the 3-D seismic data began in early October of 2000 and was completed during the first week of December. Data processing and initial interpretation were completed on May 30, 2001. The DOE-supported 3-D seismic survey covers approximately 15 square miles of Tribal minerals. The survey delineated the exact size, shape, orientation, structure and stratigraphy of the suspected Hill Creek Anticline. The Flat Rock Field is located on the north flank of this structure
