Trinity Exploration & Production, the independent E&P company focused on Trinidad and Tobago, has provided an update on operations at its Jacobin oil discovery.
As announced on 23 October 2023, the Jacobin well flowed at an encouraging rate, producing a total of 113 barrels (34 bbls oil and 79 bbls completion fluid) over a seven-hour period prior to a sand plug forming in the Well. The coiled tubing unit was deployed to clean-out the Well and was run in hole to approx. 9,700 feet. This intervention has successfully removed the blockage.
On 4 November 2023, operations to bring the Well back into production started on a 3/64th-inch choke, and were gradually increased to an 8/64th choke. The Well is cleaning-up with an initial mixed flow comprising oil, water (from the coiled tubing unit operation) and completion fluids, with no visible sign of sand at surface. The Company intends to restart the production test imminently, in order to obtain a sustained flow rate for the Well.
Trinity's current operations are focused on the deepest of three discovered oil-bearing horizons in the deeper exploration section of the Well. This is a thin zone of five feet but was highly pressured, and hence there is a risk that production on a sustained basis may be compromised. However, two thicker oil-bearing zones are located up-hole which are expected to comprise larger connected volumes of oil.
The Company will provide flow rate data when stabilised information is available, alongside details of the next phase of operations.
Jeremy Bridglalsingh, Chief Executive Officer of Trinity, commented:
'We continue to clean up the lowest of three zones in the Jacobin discovery in advance of further testing. Thereafter, we look forward to moving up-hole to carry out testing on what we expect to be the more productive upper zones. The onsite team has worked hard to progress operations and we are actively assessing the most constructive way to advance the near-term production potential of Jacobin'.
