Haynesville Shale Overview

Sandwiched between the also unconventional Cotton Valley, Bossier and Smackover formations, the Haynesville Shale is one of the most notable plays along the U.S. Gulf Coast. In addition to its overall size, the Haynesville is known for its high porosities. That makes directional drilling and hydraulic fracturing popular avenues for tapping into its gas reserves.


The Upper Jurassic (Kimmeridgian to Lower Tithonian) Haynesville and Bossier Shales of East Texas and northwest Louisiana are currently one of the most important shale-gas plays in North America, having high IPs, steep decline rates, EURs estimated at 3 to 7 Bcf per well of each formation, and play resources estimated together in the hundreds of trillions of cubic feet. Shale thickness ranges from 200 to 350 feet at producing depths of 10-14,000ft+.
