Trintes Field Operating Update

24 September 2013

Trinity, the leading independent E&P company focused on Trinidad and Tobago, is pleased to announce that the B11 sidetrack well drilled from the Trintes Bravo platform has been brought onstream at an initial gross production rate of 265 bopd. As announced in our interim results, the rig will now be demobilised to the yard to upgrade the mud systems and drilling will recommence later in the year.

Current group production is now c. 4,000 boepd (net).

Joel "Monty" Pemberton, Chief Executive Officer of Trinity, commented:

"Initial production rates from the B11 well demonstrate the Trintes reservoir ability to deliver. The upgrade plan to our rig over the next two months will significantly improve drilling efficiency and we look forward to recommencing our infill drilling programme on Trintes in November 2013."
