Haynesville Shale: Arkansas Columbia County - The Haynesville Shale is spreading into Arkansas!

A couple of gas companies drilling in the Haynesville Shale formation in north Louisiana have acquired permits to drill at three sites in Columbia County in south Arkansas.

The Haynesville Shale stretches across parts of Louisiana, Oklahoma and Texas and holds an estimated 29 to 39 trillion cubic feet of natural gas, though the range of the formation is not fully known. The Fayetteville Shale formation in central Arkansas holds an estimated 20 trillion cubic feet.It's not clear whether the companies interested in Columbia County intend to tap the Haynesville formation, but the planned wells would go quite deep. Two wells would go 8,800 feet and one would go 11,000 feet, and one is to be horizontally drilled.

Discovery of the Haynesville Shale was announced by Chesapeake Energy Corp. on March 25. Chesapeake Energy Corp. spokesman Saire Joubert says the Haynesville Shale's close proximity to Columbia County and its unknown boundaries would lead to natural gas exploration in Columbia County.
