I use the weekly rig counts from Baker Hughes, Inc., which are released on Friday. I analyze the every rig in the East Texas Basin and the Louisiana-Mississippi Salt Basins using information from the Texas Railroad Commission and Louisiana Department of Natural Resources databases. In some cases, I have to use my judgement about whether a rig is targeting the Haynesville or Middle Bossier Shales, so I welcome any input if you see an error. Please contact me at haynesvilleplay (at) gmail.com. My goal is to publish the detailed rig count over the weekend.
