JERA Co., Inc., through its subsidiary JERA Americas Inc., has completed its previously announced acquisition of upstream natural gas assets in the Haynesville shale of western Louisiana, expanding the company’s U.S. upstream and LNG-linked portfolio.
The transaction gives JERA full ownership of the South Mansfield upstream asset, acquired from Williams and GeoSouthern Energy affiliates for an upfront investment of approximately $1.5 billion. The Haynesville acquisition strengthens the company’s position across Louisiana, where it maintains a growing portfolio spanning natural gas, LNG, renewables, ammonia and carbon capture initiatives.
The South Mansfield asset is located in the core Haynesville basin and benefits from proximity to Gulf Coast pipeline infrastructure and LNG export facilities. Development plans include capturing and sequestering associated carbon dioxide from production, aligning with JERA’s lower-carbon strategy and long-term supply objectives.
JERA said the acquisition supports its broader investment strategy in Louisiana, which includes LNG offtake agreements from Cameron LNG and planned future capacity, as well as the proposed Blue Point low-carbon ammonia project and other energy investments across the state. The company has identified the Gulf Coast as a key hub for gas supply and energy infrastructure supporting global LNG markets.
Company officials said the Haynesville acquisition underscores JERA’s intention to build a long-term presence in Louisiana’s energy sector while supporting reliable gas supply and lower-carbon energy development across its global portfolio.
