HOUSTON, Apr. 5 -- A long horizontal well completed in the Bakken formation has produced oil and gas at an early 24-hr peak flow back rate, said Brigham Exploration Co., Austin.

Rate was 4,335 b/d of oil and 4.79 MMcfd of gas at the Sorenson 29-32 1H, for a combined rate of 5,133 boe/d. That rate represents an apparent record production level for the more than 2,700 horizontal wells in the Williston basin based on publicly reported date, the company said.

Brigham has a 95% working interest in the well, which was completed with 27 frac stages, perf and plug, and ceramic proppant. The well is in the Ross area of Mountrail County.

Based on this updated production performance, Brigham has completed five long-lateral high-frac stage wells in Ross with an average early 24-hr peak flow back rate of about 2,980 boe/d.
