Trinity Exploration & Production plc spudded the deep Jacobin prospect on May 15, 2023, at the Palo Seco lease operatorship area onshore Trinidad.

The well has been designed to test an extensive and lightly-drilled Miocene age deeper turbidite play mapped across the southern onshore basin and will provide new data on the play and the wider Palo Seco acreage, the company said (OGJ Online, Mar. 30, 2023). It will be drilled in virgin pressured reservoirs with higher initial production rates than conventional wells, Trinity continued.

The well is targeting a structural prospect defined on 3D seismic, with target reservoirs in the Lower Cruse formation. Reaching 9,800 ft TD, Jacobin will be the deepest onshore oil well drilled in the Palo Seco area in over a decade, according to the company.

Trinity expects the well to reach the primary target zones within 35 days. A subsequent comprehensive data acquisition plan will include a full wireline logging suite and coring of the reservoir sections.

Geological data from the well will calibrate prospectivity across the area following a 2020 purchase and subsequent interpretation and mapping of the Palo Seco NWD 3D seismic dataset, Trinity 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.

Technical work for Jacobin will also form part of an evaluation and application for adjacent Buenos Ayres block and eight other Miocene Hummingbird prospects mapped within Trinity’s existing acreage, including Emerald and Woodstar.

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