- Touchstone Exploration said it had recorded positive flow test results from a recent well drilled in Trinidad and Tobago.

The Coho-1 exploration well was drilled to a total depth of 8,560 feet and encountered about 64 feet of prospective natural gas pay.

Production testing of the Herrera Gr7b formation commenced on 16 November with a flowback period spanning seven hours using gradually increasing choke sizes.

During the final flowback period, a peak rate of 19.8m cubic feet per day of dry, sweet natural gas was observed with a certain wellhead pressure and choke size.

Given higher-than-expected initial test rates and due to equipment limitations and concerns regarding the environmental impact of the test flare, the company chose to shorten the flowback period and to conduct the balance of the testing at restricted drawdowns.

'These positive well test results represent a new era for Touchstone as we expect to add significant natural gas volumes to our production base,' chief execlutive Paul R. Baay said.

'The results outline the opportunities that still exist for onshore Trinidad exploration and position Touchstone to become a top three onshore petroleum producer.'
