Japanese energy major JERA Co., Inc. is making a decisive move into the U.S. shale gas market with its $1.5 billion acquisition of GEP Haynesville II, a joint venture between GeoSouthern Energy and Williams Cos. The transaction gives JERA full ownership of one of the Haynesville Shale’s most productive private gas portfolios, producing ~500 MMcf/d with room for expansion to 1 Bcf/d.
The newly acquired assets, located in North Louisiana’s Haynesville and Bossier formations, include approximately 200 undeveloped drilling locations. JERA plans to leverage this supply base to strengthen its growing LNG and low-carbon ammonia operations in the United States.
Why It Matters
This deal represents a major step in Japan’s strategy to secure long-term, low-cost LNG supply by integrating upstream U.S. shale production with downstream export and power operations.
-
Strategic integration – JERA now directly controls upstream gas output tied to its Gulf Coast LNG portfolio.
-
Infrastructure advantage – The acquired acreage connects to Williams’ Louisiana Energy Gateway (LEG) system, which gathers gas and delivers it toward Gulf LNG terminals.
-
Market access – The LEG network provides direct linkage to Cameron LNG, Calcasieu Pass, Driftwood, and Golden Pass LNG, enabling optimized feedgas delivery.
-
LNG supply security – JERA already holds long-term offtake agreements with U.S. LNG producers Cheniere and Sempra Infrastructure, totaling ~5.5 mtpa (~0.75 Bcf/d).
What the Map Shows
In Rextag Energy DataLink, the map highlights the emerging LNG value chain from the Haynesville core to Louisiana’s export coast:
