The Ministry of Energy and Energy Industries welcomes news of the successful completion of Appraisal operations for Perenco T&T Limited’s (Perenco) Onyx Field with gas bearing sands encountered.
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% working interest.
Appraisal drilling of this field commenced on 17th January 2025 via the drilling of the appraisal well ONYX-02B01 and its planned sidetrack, ONYX-02B02 to define the resource volumes in the East and Far East panels of the Onyx Field. ONYX-02B01 was drilled to a depth of 4,838 ft whilst ONYX-02B02 was drilled to a depth of 4,780 ft.
During the drilling of both wells, all intervals of interest were penetrated with significantly thick gas bearing sands encountered. Subsurface data was collected from both wells and are currently being used to refine geological and reservoir models with the ultimate aim of the defining the in-place volumes.
The next steps involve evaluation of the findings by Perenco to guide future development considerations which will be discussed collaboratively with the Ministry of Energy and Energy Industries and all relevant regulatory stakeholders.
The Ministry 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
