Haynesville Formation
The Haynesville Shale in Northwest Louisiana and East Texas is one of the most prolific dry gas plays in North America, with high-pressure, high-productivity wells feeding Gulf Coast LNG export terminals.
Formation Type
Shale Gas
Depth Range
10,500–14,000 ft
Basin(s)
Haynesville
States
LA, TX
Geology & Formation Overview
The Haynesville is an Upper Jurassic organic-rich calcareous shale deposited in a deep marine setting. High formation pressures (0.85+ psi/ft) and temperatures (300°F+) drive exceptional initial production rates — the highest average IPs of any US dry gas play. Depths of 10,500–14,000 ft make well costs among the highest in the sector.
