HOUSTON, June 21 -- Stone Energy Corp., Lafayette, La., has placed on production its Bonnie 1-5H well, a dual horizontal well completed in two open-hole laterals in the Mississippian Bakken formation in Richland County, Mont.

The Williston basin well encountered the Bakken at 10,370 ft. Stone drilled each horizontal lateral to 15,000 ft TMD. Average gross production is 890 b/d of oil equivalent.

Stone has a 50% working interest and 41.7% net revenue interest in the well and serves as operator. Nance Petroleum Corp., a subsidiary of St. Mary Land & Exploration Co. of Denver, is the other interest holder.

Stone's second well, the Charles Nevin 1-12H, recently had reached 10,355 ft with the first of two Bakken laterals to be commenced in June, the company said.

This year, Stone expects to drill about 22 gross wells in the Williston basin.
