Peren­co T&T Lim­it­ed has found nat­ur­al gas fol­low­ing the suc­cess­ful drilling of the Onyx well.

In a news re­lease yes­ter­day, the An­glo-French com­pa­ny said the drilling of the well and side­track in the east­ern part of the Onyx field led to the find of sig­nif­i­cant columns of nat­ur­al gas in two sep­a­rate ge­o­log­i­cal com­part­ments.

Peren­co T&T’s gen­er­al man­ag­er Gre­goire de Cour­celles said, “I am very proud of the suc­cess­ful re­sults of the Onyx wells. 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 pro­vide fu­ture sup­plies of nat­ur­al gas to Trinidad and To­ba­go. I would like to thank our part­ners Her­itage Pe­tro­le­um and NGC for their un­wa­ver­ing sup­port in this project and con­grat­u­late all teams in­volved in com­plet­ing this op­er­a­tion safe­ly and ef­fi­cient­ly.”

Peren­co has been pro­duc­ing hy­dro­car­bons in Trinidad & To­ba­go since 2016, when it took over op­er­a­tor­ship of the Teak, Samaan and Poui (TSP) fields, lo­cat­ed off­shore the south-east coast of Trinidad.

The re­lease stat­ed the Onyx field is an un­de­vel­oped gas dis­cov­ery lo­cat­ed with­in the TSP li­cense, in a wa­ter depth of 180 ft, be­tween the Poui and Teak fields, off Trinidad’s south-east coast.

TSP is a joint ven­ture be­tween Peren­co T&T, the op­er­a­tor, Her­itage Pe­tro­le­um Com­pa­ny and Na­tion­al Gas Com­pa­ny of Trinidad and To­ba­go.

The com­pa­ny said sub­sur­face in­for­ma­tion is cur­rent­ly un­der re­view and de­vel­op­ment op­tions will be eval­u­at­ed to move the dis­cov­ery to­wards fi­nal in­vest­ment de­ci­sion (FID).

In De­cem­ber 2024, Peren­co ex­pand­ed its op­er­a­tions in T&T with the ac­qui­si­tion of the Cashima, Amher­s­tia, Flam­boy­ant & Im­mortelle (CAFI) gas pro­duc­ing as­sets. On March 28, 2025, the com­pa­ny signed an agree­ment to ac­quire the par­tic­i­pat­ing in­ter­ests of Wood­side En­er­gy in Blocks 2c and 3a (Greater An­gos­tu­ra), which is pro­gress­ing to­wards com­ple­tion.
