Breakthrough oil discovery in Trinidad & Tobago

UK company has found what it describes as “virgin oil in a super-mature basin” onshore Trinidad and Tobago with over 290 feet of net oil pay at the Jacobin-1 well.

The operator said today it had successfully encountered hydrocarbons at the Jacobin-1 well in the prolific Palo Seco area, onshore Trinidad, drilling to a total depth of 10,021 feet – one of the deepest wells drilled in recent times within the Palo Seco area.

The well hit 290 feet of net oil pay including 63 feet of net oil pay in the deeper exploration targets.

The well was spudded on 15 May 2023 with an objective to appraise and explore the potential of Lower Cruse sandstones within the Palo Seco area of the prolific Southern Basin.

A comprehensive logging and pressure sampling programme confirmed virgin pressures in these deeper zones.

The company said the results validated the geological model and were within the pre-drill range for a commercial discovery.

Flow testing is planned to confirm the deliverability of these reservoirs, expected to begin in September.
