Marubeni Closes EagleRidge Energy Acquisition and Exits Big Foot Gulf of Mexico in US Portfolio Rotation

Marubeni Corporation completed two North American energy transactions in quick succession this month. The Japanese trading company closed its acquisition of EagleRidge Energy, a Barnett Shale gas producer, on July 7, 2026. One day later, Marubeni announced the sale of its interest in Big Foot, a deepwater oil field in the US Gulf of Mexico.

EagleRidge Energy: 100 Percent Acquisition of a Barnett Shale Gas Producer

Marubeni announced the acquisition of all membership interests in EagleRidge Energy on June 17, 2026. Oil & Gas Journal confirmed the deal closed by July 7, 2026. EagleRidge Energy operates natural gas development and production assets in the Barnett Shale formation in North Texas. Financial terms were not disclosed in Marubeni's announcement or subsequent reporting.

The Barnett Shale underlies the Fort Worth Basin and was the first major commercial shale gas play in the United States. The formation reached peak output in the early 2010s and has since transitioned to a lower-decline, infrastructure-rich production base. Existing wells and gathering systems require less incremental capital than active unconventional development basins, providing stable gas volumes without high new-well costs. Acquiring 100 percent of EagleRidge gives Marubeni full operational control of a US gas producer, contrasting with the minority partnership position it held in Chevron-operated Big Foot.

JKM-Henry Hub Spread at $13.29 per MMBtu Frames the Strategic Case

Henry Hub natural gas settled at $3.29 per MMBtu on July 10, 2026, per LNGPriceIndex.com. The Japan-Korea Marker, the primary Asian LNG spot benchmark, settled at $16.58 per MMBtu on the same date. The spread between the two benchmarks reached $13.29 per MMBtu, meaning Asian spot LNG traded at more than five times the US domestic gas price.

For a Japanese trading conglomerate with LNG marketing operations in Asia, securing upstream US gas production at domestic prices enables access to supply that can reach Asian buyers through Gulf Coast LNG export facilities. The Barnett Shale's location in Texas, within pipeline reach of those terminals, reinforces the commercial logic of the EagleRidge acquisition. Henry Hub at $3.29 per MMBtu is among the lowest major-basin gas prices in the world, making US production an attractive LNG feedstock.

Big Foot Gulf of Mexico: Exit from Chevron-Operated Deepwater Oil

On July 8, 2026, Marubeni announced the sale of its interest in Big Foot, an oil and gas field in the US Gulf of Mexico. Chevron Corporation operates Big Foot, a deepwater installation that produced its first oil in 2018. Marubeni did not disclose the buyer or the sale price.

Offshore deepwater projects carry higher per-barrel lifting costs and longer capital commitment timelines than onshore shale plays. Releasing capital from a minority stake in a Chevron-operated deepwater field and redeploying it into a 100 percent-owned Texas gas company reduces both operational overhead and offshore platform risk exposure. The divestment also reduces Marubeni's exposure to long-term maintenance costs as the Big Foot installation ages.

Japanese Trading Houses and the North American Gas Buildout

Marubeni is one of Japan's five major sogo shosha, or general trading companies. These firms hold upstream energy positions to secure supply for downstream Japanese industrial and utility customers while generating margins across the value chain. As US LNG exports have grown since 2016, Japanese trading houses have expanded their focus on North American gas assets that feed into LNG export chains.

The Canadian Association of Petroleum Producers reported in July 2026 that Canada's federal government and British Columbia signed a memorandum of understanding to accelerate LNG infrastructure. CAPP also cited Canada's inaugural LNG supply agreement with a European buyer, noting it strengthens the commercial viability of the Ksi Lisims LNG project in British Columbia. Marubeni's parallel move into Barnett Shale production reflects the same strategic thesis: North American gas has decades of affordable supply available for delivery to Asia and Europe.
