HOUSTON Frontera Energy and CGX Energy expect to make a final investment decision (FID) by 2026 on developing a promising block offshore Guyana, with first oil output potentially by 2030, executives from the companies said on Dec. 11.

The Frontera-CGX joint venture (JV) could become the next group to advance an oil and gas exploration project in Guyana after an Exxon Mobil-led consortium. That group began output in 2019 and is this year producing some 400,000 bbl/d.

US investment banking firm Houlihan Lokey has been retained to help Frontera and CGX pursue options for a possible deal to find partners for developing the Corentyne Block's potential, they said in a release.

The appraisal of the entire area is expected to be finished in 2025. If a positive FID is made, the consortium would move to topsides construction for an FPSO vessel, drilling and subsea architecture.

The companies and subsidiaries had exploration licenses for several large blocks in Guyana, but in 2022 they agreed to focus on Corentyne following discussion with Guyana's government.

Guyana recently received bids from international and local firms for eight new blocks to be awarded soon.

The JV retained Subsea Integration Alliance, an oilfield services group by SLB's OneSubsea and Subsea7, to complete a conceptual field development plan for Corentyne, it said during the presentation.

The timeline for Corentyne's development comes after the firms analyzed data from the Wei-1 exploration well, where they identified medium sweet oil, but they have not yet estimated the area's full potential, said Mark Zoback from CGX's board of directors.

The JV has identified gross prospective resources of between 514 MMbbl and 628 MMbbl of oil and gas in the Maastrichtian horizons alone, and additional potential in the deeper Campanian and Santonian horizons.

"We are working on the deeper zones; it's high priority," Zoback said.

Frontera and CGX believe that the rock quality discovered in the Maastrichtian horizon is analogous to that reported in Exxon's Liza discovery.
