WESTERN HAYNESVILLE
Information
The "Western Haynesville" is a quickly evolving play based on the deep Haynesville and Bossier geological formations. Comstock Resources was the early mover and Aethon has followed suit. Both companies have built large leasehold positions and drilled impressive wells. Other major unconventional O&G companies are joining them as the play area expands. Mitsui E&P USA has built a large position and Expand (Chesapeake) is heavily rumored to be leasing. There may be more major operators chasing this trend via the multiple brokerage firms that are active in the eastern expansion of the trend. The play area originally was comprised of Leon, Roberston and Freestone counties as the focus for early drilling. Leasing operations and "trend subsurface work" has seen the play expand to include Houston, Anderson, Cherokee and Nacogdoches counties. The eastward expansion to Nacogdoches County now almost connects the western trend to the original Haynesville Shale fairway. The prospective section in this trend ranges from 2000' to over 4000' thick, and the opportunity for multiple target intervals is highly probable based on some stacked lateral efforts by Comstock. The play is deep, hot and over pressured making it an expensive and challenging trend to drill, fracture stimulate and produce.
Location: Leon, Roberston, Freestone, Houston, Anderson, Cherokee and Nacogdoches counties.

Dave, your area as described is definitely the productive trend and will work (barring drilling and /or mechanical issues). Getting deeper - and more expensive in your area.

Thanks- We are 4-5 five miles east of the Mitsui location. Getting close! If I still lived in The Woodlands I would be sniffing around the shakers ! HaHa I spent 40 years in Drilling, all overseas.

Comstock’s Haynesville Natural Gas Set to Power Texas Data Centers in Collab with NextEra
By Carolyn Davis Published in: Daily Gas Price Index Filed under:
Haynesville Shale pure-play Comstock Resources Inc. is making the leap from producing natural gas to generating power in a collaboration to use its considerable East Texas output to keep the lights on at a plethora of data centers in the state.
The collaboration with NextEra Energy Resources LLC, a unit of Florida-based utilities giant NextEra Energy Inc., was disclosed in Comstock’s second quarter results.
As envisioned, the generation would be built near Comstock's western Haynesville area, which extends across several counties basically 100 miles each way between the two largest metropolitan areas: east of the Greater Houston area and south of the Dallas Metroplex.
