Japan’s JERA to acquire US shale asset for $1.5 billion

BATON ROUGE, October 23, 2025 – Japan’s JERA has agreed to acquire the South Mansfield shale gas asset in the Haynesville Basin in western Louisiana, USA, for USD 1.5 billion, the company said on Wednesday.

The asset, currently producing more than 14.2 mcm (500 mcf) per day, includes 200 undeveloped locations and spans around 210 square kilometres. JERA plans to boost production to 28.3 mcm (1 bcf) per day following the acquisition.

The deal, made through its subsidiary JERA Americas, was signed with Williams and GEP Haynesville II. It includes access to existing infrastructure and proximity to Gulf Coast LNG and data centre hubs.

“This upstream Haynesville acquisition is a strategic addition to our asset portfolio, enabling us to advance our unique supply chain expertise,” JERA Americas CEO John O’Brien said.

JERA is Japan’s largest power generation company and a major global LNG player. It operates across the energy supply chain, with investments in upstream gas, LNG procurement, and power generation. The company is targeting net-zero CO2 emissions across its operations by 2050.

In the USA, JERA owns stakes in 10 power generation assets and recently signed a long-term LNG offtake agreement for 5.5 million tonnes per year over 20 years. It is also advancing a low-carbon ammonia project at Blue Point.
