Touchstone finds ‘liquids rich’ natural gas discovery in Trinidad

Touchstone Exploration has announced that tests on its Cascadura Deep-1 well have confirmed the presence of liquids rich natural gas.
Touchstone has an 80 per cent operating working interest in the well, which is located on the Ortoire block onshore Trinidad.
The company said it perforated the top 199 feet of the 449 feet identified as potential pay in sheet four of the over thrust Herrera formation on April 8, 2021.
The average flowback rate during the extended 24-hour test period was approximately 4,262 barrels of oil equivalent per day (boe/d), including 22.9 MMcf/d of natural gas and 449 bbls/d of NGLs.
Peak flowback rate of approximately 4,567 boe/d was observed, comprised of 24.5 MMcf/d of natural gas and 477 bbls/d of NGLs.
Approximately 48.8 MMcf of natural gas (8,138 boe) and 1,081 barrels of NGLs were produced during the testing period.
Field analysis indicated liquids rich gas with no hydrogen sulphide and no produced water.
The well is currently shut-in for a minimum four-week pressure build-up test.
In a statement, Paul Baay, Touchstone’s President and Chief Executive Officer, commented: "The positive test results from Cascadura Deep-1 further expands the opportunity on the Ortoire block as we now expect to have two distinct and separate sheets producing from two wells in the Cascadura structure.”
“We will accelerate operations required to bring the two Cascadura wells onto production as the test results allow us to properly size surface facilities for reservoir management. We are also moving forward with the required applications to establish a second Cascadura surface location, designed for up to four development wells. The test results demonstrate the clear future production opportunities for the Company."
James Shipka, Chief Operating Officer, said: "The exceptional performance noted during Cascadura Deep-1 well testing reinforces the geological concept of multiple stacked, independent hydrocarbon charged horizons in the Herrera turbidite fairway.”
“We will not be conducting any up-hole testing in the well as we do not want to interrupt this interval at the risk of damaging the reservoir with water-based fluids. The data collected in this flow test indicates that sheet four is separate from sheet three, where production is expected from the Cascadura-1ST1 well. There remains an additional 558 feet of potential pay above the tested zone in sheet three which can be evaluated in future development wells."
Extension of Lease Operatorship Agreements between Touchstone and Trinidad and Tobago’s Heritage Petroleum for the Coora-1, Coora-2, WD-4 and WD-8 blocks has been extended to April 30, 2021.
The LOAs were originally set to expire on December 31, 2020 and were previously extended to March 31, 2021.  Source: Newsday April 2021
