PORT OF SPAIN, Trinidad, CMC -The Trinidad and Tobago government welcomes the successful completion of appraisal operations for Perenco Trinidad and Tobago Limited’s (Perenco) Onyx Field, which encountered gas-bearing sands.
The Onyx Field was previously discovered through exploration drilling offshore South East Trinidad in the Columbus Basin between the Teak and Poui fields.
“This field is operated by Perenco with a 70 percent working interest. Appraisal drilling of this field commenced on 17 January 2025 via the drilling of the appraisal well ONYX-02B01, and its planned sidetrack,” the Ministry of Energy and Energy Industries said in a statement.
Earlier this week, Perenco said it found “significant columns” of natural gas in two separate geological compartments on the eastern part of the Onyx field, an undeveloped gas field.
In a statement, Perenco said the gas discovery was made at a depth of 180 feet between the Poui and Teak fields and that it is currently reviewing subsurface information.
“Development options are expected to be evaluated to move the discovery toward a final investment decision,” it said.
“Our objective was to prove sufficient gas reserves to unlock field development. The wells’ findings are testimony to the hydrocarbon potential which remains in the TSP acreage and highlights Perenco’s commitment to providing future supplies of natural gas to Trinidad and Tobago,” said Perenco’s general manager, Gregoire De Courcelles, who described the discovery as a significant milestone in the company’s vision for TT.
The Teak, Poui, and Samaan fields (TSP) are under license by a joint venture between Perenco TT, Heritage Petroleum Co Ltd, and the National Gas Company (NGC).
De Courcelles thanked the partners for their support of the project.
In its statement, the ministry said it “views these findings as a very positive development for Trinidad and Tobago’s energy sector as we continue to work with stakeholders such as Perenco to maximize the production of our natural resources for the benefit of the citizens of the Republic of Trinidad and Tobago.”
