Chuska Energy Co., San Antonio, has boosted production on the Navajo Indian reservation to 4,000 b/d of oil and 5 MMcfd of gas.

The company, operating in the area since 1983, is producing from 13 oil wells in Utah and five gas wells in Arizona. About 1,200 b/d is net to Chuska.

It plans to drill 30-40 algal reef mound wildcat in the Paradox basin during 1991.

Chuska reached TD in late January at three more algal reef mound wildcats and is completing two step-outs, 17E-2 Monument, NW SW NW 17-40s-25e, and 10-C-5 Runway Reef Mound, NE NE NW 10-40s-25e.

All of the wells listed are in San Juan County, Utah.

The five wells are expected to increase oil production from the Desert Creek member of the Pennsylvanian Desmoinesian Paradox formation by about 1,800 b/d, of which 500 b/d would be net to Chuska.

Chuska's 1-J-1 Blue Hogan, NE NW SE 1-42s-23e, appears to have five pay zones within 5,400-5,562 ft. The zones have logged individual flow rates of 870, 850, 840, 820, and 1,240 b/d of oil, accompanied by gas flows of 390-730 Mcfd.

The well is being connected to a gathering system and is expected to produce a sustained 600-800 b/d.

Chuska's 12-F-1 Lone Mountain Creek, NW SE NW 12-42s-24e, tested a combined 1,400 b/d through a 21/64 in. choke from three intervals between 5,315 ft and 5,460 ft. The 33-1-1 Navajo Canyon wildcat, SW NE SE 33-39s-25e, is awaiting completion.

Chuska was drilling the 11 A-1 Coral, NE NE NE 11-43s-25e, toward TD 6,250 ft.

During 1990, Chuska brought six oil wells and two gas wells on production.
