– Unit Corp., Tulsa, plans to run two rigs from now throughout 2011 in a Pennsylvanian Marmaton horizontal oil play in Beaver County in the Oklahoma Panhandle.

The company has reduced drilling time at the last four wells to an average 13 days, $630,000/well cheaper than the earlier 27-day average.

Ten horizontal wells were awaiting completion as of Sept. 30 because of delays in availability of third-party completion services. Unit was able to successfully frac eight of the 10 wells by the end of October, and the first three wells were producing at peak rates of 497, 484, and 169 b/d of oil equivalent in early November. Working interest averages 91%.

Completion of the other five wells started in late October. Unit scheduled two frac dates in November, three in December, and is working to secure about three frac dates per month for 2011 in the play.
