Touchstone Exploration Inc. announces the completion of flowback testing of the Cascadura Deep-1 well, confirming a liquids rich natural gas discovery. Touchstone has an 80% operating working interest in the well, which is located on the Ortoire block onshore Trinidad and Tobago (Heritage Petroleum Company Limited ("Heritage") holds the remaining 20% working interest). Touchstone perforated the top 199 feet of the 449 feet identified as potential pay in sheet four of the overthrust Herrera formation on April 8, 2021. The average flowback rate during the extended 24-hour test period was approximately 4,262 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 sulfide and no produced water. The well is currently shut-in for a minimum four-week pressure build-up test. Cascadura Deep-1 well production testing commenced on April 8, 2021, with flow tests spanning a total of 58 hours, comprised of an initial clean-up flow period, followed by an initial shut-in period and a five-step rate test, including a 24-hour extended flow test. Well testing was conducted by an international well testing and measurement company. During the extended flow test period, the well achieved a peak production rate of approximately 4,567 boe/d (90% natural gas). This production rate included approximately 24.5 MMcf/d of natural gas and 477 bbls/d of NGLs flowing at 1,917 psi. During the 24-hour extended portion of the flow test, the well averaged a production rate of approximately 4,262 boe/d (89% natural gas), including 22.9 MMcf/d of natural gas and an estimated 449 bbls/d of NGLs. The flowing pressure of the well during this stage of testing averaged 1,856 psi through a 50/64-inch choke. Approximately 48.8 MMcf of natural gas (8,138 boe) was produced during testing, with 1,081 barrels of NGLs and 27 barrels of water which were less than the load fluid used in the well. During testing, Cascadura Deep-1 yielded 59.5-degree API gravity NGLs at an average ratio of approximately 22 barrels of NGLs per MMcf of natural gas produced. Field analysis of the produced gas indicated liquids rich natural gas with no hydrogen sulfide content. Additional testing of fluid samples will be conducted to accurately assess the gas and associated liquids composition. The well is currently shut-in for an extended pressure build-up survey for a minimum of four weeks to identify possible formation boundaries. Touchstone will not conduct further testing of the well and intends producing the well concurrently with Cascadura-1ST1.
