Canada-based Touchstone Exploration has announced test results from the Cascadura-1AT1 well onshore Trinidad, in the Caribbean.

The company said average flow from its well in the Ortoire block was over 10,600 barrels per day (bbls/d). It carried out tests on the liquids-rich gas deposit over two stages.

The first tests looked at the deepest 162 ft (49 m) of pay. There, peak flow was between 7,750 and 9,700 barrels of oil equivalent per day (boe/d). The well also produced 865 barrels of natural gas liquids per day (bbls/d), with 40 to 50 million cubic feet per day (MMcf/d).

The second stage of tests looked at another 345 ft (105 m) of pay above. It encountered peak flow of 5,760 boe/d of oil equivalent, with 15% liquids. Natural gas liquids flowed at a peak rate of 865 bbls/d, while natural gas flow peaked at 29.4 MMcf/d. Laboratory tests revealed no hydrogen sulphide or measurable solids.

Production testing on the second stage began on 8 March. The well has now been shut-in to build pressure for testing. Pressure recorders will be recovered next month, and data will be used to calculate the total available resources.

Tie-in expected

The test well is close to other Touchstone wells in Trinidad, such as the Coho-1 well. This will begin production in Q3 2020, and the company hopes to tie-in the new well. It has surveyed the pipeline site, and is inviting bids from contractors for the construction.

Touchstone president and CEO Paul Baay said: “In addition to estimated production at our Coho discovery and our existing production, this well gives us a clear path to 10,000 boe/d with an estimated 75% natural gas and 25% liquids product mix.

“With domestic demand for natural gas exceeding current production, Touchstone is working with industry partners to bring these new volumes on-stream as quickly as possible. With the Cascadura well only three kilometres from existing infrastructure, we are evaluating the most efficient path forward to tie these significant volumes into the domestic sales network.”

The company is testing another well 1km south of the Cascadura-1ST1 well, which will spud in Q2 2020.
