Trinidad: Trinity Exploration provides update on operations at the Jacobin oil discovery

20 Nov 2023

AIM-listed Trinity Exploration & Production, the independent E&P company focused on Trinidad and Tobago, has provided an update on operations at its Jacobin oil discovery.

Operations on the Jacobin well are now focussed on flow testing the discovered oil zones in the Lower Cruse 1 ('LC1') upper intervals. Testing of the thin Lower Cruse 3 ('LC3') zone is being terminated, as despite clearing the sand blockage (as reported on 8 November 2023), further sand production issues were still experienced. Laboratory analysis of produced fluids and reservoir grain size and composition is on-going in order to assist with Company's assessment of the future production potential of this zone.

The upper two zones are well developed oil-bearing sandstone intervals, with thicker net pay zones for testing (with a combined test interval circa five times that tested at the LC3 level), and generally better developed than the deeper reservoir encountered at the LC3 level. We believe the risk of experiencing material sand production issues is much reduced at this level but will be carefully monitored regardless as testing proceeds.

The testing of the upper zones will be conducted by perforating via wireline and the rig is at the well site conducting preparatory work.  All regulatory approvals are in place for the next phase of the testing programme.

The Company expects to perforate the upper zones in the well by mid-December. Reservoir behaviour will be closely monitored during the production testing phase and the testing regime will be adjusted in line with the well's performance. 

The Company will keep the market informed of progress on the next phase of operations on the Well.

Jeremy Bridglalsingh, Chief Executive Officer of Trinity, commented:

'We are moving up-hole to commence testing of the main zones of interest. The well-testing team has worked hard to try to achieve production from what was always going to be a challenging zone but we will now take the valuable operational lessons learned and data gathered, up-hole to what is expected to be more productive zones.'
