Eagle Ford Shale Rig Count – September 30, 2011

Drilling Rig PhotoThe Eagle Ford Shale rig count dropped 3 rigs to 236 active drilling rigs. That’s down from an Eagle Ford era record of 239 last week.

The number of natural gas rigs working dropped 3 to 118, while the oil rig count remained flat at 118. Horizontal wells account for 210 of the 236 rigs drilling in the South Texas region. La Salle and Dimmitt counties were the only two to add any rigs, while Gonzales County accounted for most of the lost rigs with 5. No other county lost more than 1 rig.

Chesapeake Energy (29) is the only operator with more than 20 rigs active in the play.  12 companies have more than five active drilling units.
