Noble Energy EG and Noble Energy Cameroon (both Chevron companies) have reiterated Chevron’s commitment to the development of the Yoyo-Yolanda Project, as the Republic of Equatorial Guinea (“EG”) and the Republic of Cameroon signed the unitization agreement for the project on February 3, 2026. 

Jim Swartz, Chairman and Managing Director Chevron Nigeria and Mid-Africa Region explained that the Yoyo‑Yolanda Field is a cross‑border offshore gas field shared between Equatorial Guinea and Cameroon, containing an estimated 2.5 TCF of gas in place. 

“The Yoyo‑Yolanda project is central to Chevron’s strategy of supporting long‑term Liquefied Natural Gas (“LNG”) supply and leveraging existing infrastructure at Alen and Punta Europa,” he stated. 

“The agreement enables Chevron and its partners to continue to advance the Yoyo-Yolanda project,” Jim added. 

On March 18, 2023, the Republic of Equatorial Guinea and the Republic of Cameroon signed a bilateral treaty between the two countries. The agreement paved the way for the joint development of oil and gas reserves at the two countries’ maritime border in the Gulf of Guinea including the Chevron-operated Yoyo and Yolanda fields. 

Yoyo-Yolanda Project

The Yoyo-Yolanda Project is a major offshore natural gas development initiative focused on exploiting a gas-condensate reservoir that spans the maritime boundary between Cameroon and Equatorial Guinea in the Gulf of Guinea. The Yoyo discovery lies in Cameroon’s Douala Basin and the Yolanda discovery sits directly across the border in Equatorial Guinea’s Block I; seismic and well data from both indicate they form a single contiguous resource, and for this reason the two nations agreed to develop them jointly rather than separately. The fields were originally discovered in 2007 by Noble Energy (now part of Chevron) and contain an estimated 2.5 trillion cubic feet of natural gas. 

A bilateral cooperation treaty signed in 2023 and subsequent legal agreements have effectively unitized the separate leases into a single development area, enabling coordinated planning and investment by Cameroon, Equatorial Guinea and Chevron as operator, with the aim of producing gas efficiently and capitalizing on existing infrastructure such as the Alen and Punta Europa facilities. The project is seen as central to long-term liquefied natural gas (LNG) supply strategies for the region and a way to support broader downstream gas infrastructure and economic growth in both countries.
