CALGARY, AB, May 25, 2021 /CNW/ – Touchstone Exploration Inc. (“Touchstone”, “we”, “our”, “us” or the “Company”) (TSX: TXP) (LSE: TXP) provides an operational update, highlighted by the recovery of pressure gauges from the Cascadura Deep-1 well on the Company’s Ortoire onshore exploration block in Trinidad (Touchstone 80 percent working interest operator, Heritage Petroleum Company Limited 20 percent working interest).
As previously announced, the Cascadura Deep-1 well was completed over a 199-foot-thick interval in Sheet Four of the overthrust Herrera Formation. Following production testing operations, the well was shut in for a pressure buildup test on April 11, 2021, and the pressure gauges were recovered on May 17, 2021.
Cascadura Deep-1 Testing Highlights
Buildup test data showed no depletion with a final bottomhole pressure of 4,746 psi, confirming a substantial liquids rich gas discovery.
Analysis of buildup data showed the test was unbounded with a minimum radius of investigation of 1,500 feet, confirming the significant size and reserves potential of the pool.
While the well test data indicated that the formation was damaged, we are confident that the well will require no stimulation and that flow rates will be consistent with those during testing (average flow back rate of 22.9 MMcf/d of natural gas and 449 bbls/d of NGLs).
Natural gas produced during the production test was approximately 94…
