The Arkansas Oil and Gas Commission has reported 11 new completions in the Fayetteville shale for the past week as well as 13 new permits.

The report comes just as a warning that growth in unconventional gas supplies could slow down in 2009-2010 was sounded by Pritchard Capital Partners LLC senior analyst Ray Deacon.

“Natural gas fundamentals have been overwhelmed by soaring unconventional values year-to-date and de-bottlenecking projects in the Rockies, Gulf and Midcontinent,” Deacon says. Growth will slow, he says, as development in the Barnett shale slows.

The Arkansas commission reports that Petrohawk Energy Corp., Houston, (NYSE: HK) was the leader of the pack with eight completions; Southwestern Energy Co., Houston, (NYSE: SWN) filed two; and Storm Cat Energy Corp., Denver, (Amex: SCU) with one. The commission reports that initial production rates were given on all but one of Petrohawk’s completions,

Petrohawk’s seven published rates averaged 2.1 million cubic feet equivalent per day, including one that averaged 5 million cubic feet equivalent per day. Southwestern reported that its two completions averaged 4.3 million cubic feet equivalent per day and 4.1 million cubic feet equivalent per day. Storm Cat’s one completion average 1.1 million cubic feet equivalent per day.

A breakdown of the counties involved: Conway County, one; Van Buren with nine; and Cleburne, one.

Of the 13 new permits issued by the commission, Southwestern had nine with three each in Van Buren and Conway and one each in Faulkner, Cleburne and Logan counties; Chesapeake Energy Corp., Oklahoma City, (NYSE: CHK) had three with two in White County and one in Faulkner county; and XTO Energy Inc., Fort Worth, Texas, (NYSE: XTO) had one in Cleburne.
