Trinity encounters oil in Jacobin well onshore Trinidad

Trinity Exploration & Production PLC encountered oil in the shallow secondary formations of the Jacobin well, onshore Trinidad.

The well was spudded on May 15 to test an extensive and lightly-drilled Miocene age deeper turbidite play mapped across the southern onshore basin (OGJ Online, May 22, 2023). It has completed two of three planned sections and has intersected the Forest and Upper Cruse secondary targets encountering good quality oil-bearing reservoirs, the company said. 

An intermediate logging program has been completed and initial analysis shows good quality reservoirs and pay zones which have exceeded pre-drill estimates.

The rig is setting casing and is preparing to drill ahead into the third section, during which it is expected to encounter the primary well targets in the deeper Lower Cruse reservoir formations (TS-6, TS-7, TS-8), through to prognosed TD expected in about 2 weeks.

The drilling schedule has been extended due to the company's decision to accelerate the changeover to synthetic oil-based mud in the second section (which had been planned for the third section) in response to challenging drilling conditions, which, once initiated, led to a rapid and material improvement in drilling progress, the company said.

Target resource volume is 5.7 million bbl mean oil in place and an upside (P10) case of over 10 million bbl in-place.

Data provided from Jacobin will help to de-risk further Lower Cruse drilling across the Hummingbird prospects, including the Buenos Ayres block.

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