Privately held, Centennial, Colo.-based Running Foxes Petroleum Inc. and its 50% partner report the recent Great Plains Field discovery in Colorado has two wells producing 300 to 600 barrels per day completed in the Excello shale of the Cherokee Formation.

Two of the three wells being drilled in Bolero Field in Lincoln County, the Craig 6-4 and Craig 16-32, are development wells. The third well, John Craig 11-2, is in Running Foxes’ Aloha More Mula project in Lincoln County. The Aloha More Mula project lies three miles to the north of Great Plains Field in Lincoln County and expects to see similar results from the same shales and carbonates.

The Craig 16-32 is a direct offset from three producing wells in Bolero Field. These wells are producing oil from thin Atoka and Cherokee shales, limestones and dolomites. The Craig 6-4 is a development well in Bolero Field. Running Foxes’ previously drilled Craig 6-4SWD well encountered several oil shows in the Cherokee and Atoka shales and in the interbedded porous dolomites and limestone.

The John Craig 11-2 well is a rank wildcat that is targeting a structural closure defined by Running Foxes’ 3-D seismic survey of the Aloha More Mula project. The 3-D seismic survey identified 50 to 100 feet of structural relief in the Paleozoic rocks and significant faulting around the target.

The southern part of the Denver Basin is known for production from Morrow and Mississippian reservoirs below the Pennsylvanian Cherokee and Atoka shales. However, the source of oil in these conventional reservoirs west of the Las Animas Arch has never been identified, according to Running Foxes.

Running Foxes has oil and gas operations in the Cherokee and Sedgwick basins in Kansas, the Denver Basin in southeastern Colorado and the Uncompahgre uplift in Utah.
