New Monster Gas Wells Are Outperforming Legacy Haynesville Deposits

New Monster Gas Wells Are Outperforming Legacy Haynesville Deposits

By Rystad Energy - Nov 24, 2025

  • The Western Haynesville gas play is gaining attention for its highly productive, deep, and overpressured wells, which are up to twice as productive as median legacy Haynesville wells.
  • The high productivity comes with a high cost, as drilling and completion (D&C) expenses are currently around $35 million per well, which is triple the cost of legacy Haynesville wells.
  • For the play to be economically viable and become a major supply source, operators must reduce D&C costs to approximately $25 million, which could enable the region to reach nearly 2 Bcfd of production by the end of 2030 with an eight-rig development program.

Aethon, in particular, has completed a number of prolific Western Haynesville wells.  They seem to outperform Comstock's typical well, perhaps due in  part to a variable choke system that they have mentioned in public comments.

Here are some numbers for Aethon's first Western Haynesville wells.  The date of first production, total production through October 2025,  and the 12/25/2025 expected ultimate recovery (as calculated by Enverus) are shown for each well.

Thanks, Alan.  Those EUR numbers are crazy.  The Western Haynesville has become the next big natural gas play.  The historic Haynesville fairway will continue to do well but the real loser will be Marcellus gas.
