Trinity Exploration & Production PLC found multiple oil-bearing sandstone reservoirs in the Lower Cruse section of the Jacobin well sidetrack onshore Trinidad.

The well spudded May 15, 2023, to test an extensive and lightly-drilled Miocene age deeper-turbidite play mapped across the southern onshore basin (OGJ Online, June 26, 2023). It was drilled to 9,325 ft at which depth unexpected wellbore conditions prevented further progress, necessitating a sidetrack. The sidetrack is being drilled and the well will continue to drill to the planned depth of about 10,000 ft, expected to be achieved in 2 weeks.

During sidetracking, the well penetrated more than 2,000 ft into the Lower Cruse. Preliminary evaluation, using a combination of measurement while drilling (MWD) data (inclusive of MWD gamma ray) together with analysis of wellbore cuttings, point to at least three well-developed, oil-bearing sand intervals in the Lower Cruse.

Further data will be collected from the sidetrack, including a full logging suite. The well has successfully intersected the Forest and Upper Cruse secondary targets, and analysis has confirmed that the total net hydrocarbon pay across these targets is 228 ft.

Trinity holds 100% interest in the Palo Seco area sub-licenses.
