Resolute acquired its Wyoming producing properties in 2008, located in Hilight Field in the Powder River Basin about 20 miles south of Gillette, Wyoming. Hilight Field is a large stratigraphic trap in the Muddy sandstone that was discovered in 1969. Waterflooding was initiated in the early 1970s and expanded through the late 1990s. Since that time the field has been produced without waterflood. Infill drilling was implemented over a small portion of the field in the mid-2000s, and a small number of wells have been restimulated. Resolute operates three federal units of Hilight Field: Jayson Unit, Grady Unit and Central Hilight Unit. SEC reserves in Hilight as of year-end 2013 are approximately 18% oil, 27% NGL, 55% natural gas.
All of the production from the Wyoming properties comes from conventional reservoirs. Resolute operates all of these properties, with per-well working interest averaging approximately 90%.
In addition to the existing production resource, Resolute has been investigating uphole opportunities, including:
- A Mowry formation recompletion program. Eleven Mowry wells in Hilight Field were recompleted as of September 30, 2014
- A 3D seismic program over Hilight Field to better understand the potential for Muddy formation infills, Mowry formation completions, and reserves and production from the uphole Turner and Niobrara formations
- A horizontal exploratory test of the Mowry shale in the Big Horn Basin on 67,900 net acres owned by Resolute.
