GeoSouthern, Williams Market Haynesville Gas Assets

Joint venture partners GeoSouthern Energy and Williams Cos. are marketing natural gas assets in the core of the Haynesville, where buyer demand is increasing but M&A targets are scarce.

Private producer GeoSouthern Energy Corp. is taking bids for its Haynesville natural gas assets, three sources told Hart Energy.

GEP Haynesville II, a joint venture (JV) between GeoSouthern Energy and Williams Cos., operates around 50,000 net acres in Louisiana’s Haynesville Shale.

Analysts estimate GEP Haynesville II’s coveted acreage could fetch between $1.2 billion to $1.5 billion through a potential sale.

GeoSouthern has had two Haynesville shale focused operating companies:  GEPH and GEPH II.  The first ceased business when Vine and GeoSouthern sold to Chesapeake and the second is the current operator of the Haynesville Shale units that Williams Company received as compensation in its lawsuit with Chesapeake.  GEPH II has been active in searching for "step out" areas to expand the Haynesville fairway.  Last year the company formed a Haynesville drilling and production unit in the Pendelton-Many Field ( Sections 24&25 - 7N-12W) and has been reported to be leasing in the Robeline area of Natchitoches Parish.

GEPH and Vine were originally 50/50 partners in the acreage they purchased from Encana.  The two companies then split the acreage, and each company operated their portion of it at 100% WI.  GEPH was acquired by SWN in late 2021, which later merged with CHK to form Expand.  Vine was purchased by CHK in 2021.  GEPH II formed a JV with Williams to operate the acreage around Mansfield that Williams acquired from CHK during the CHK bankruptcy.
