Touchstone announces Cascadura-5 well drilling results
Touchstone Exploration provided an operational update on the Cascadura-5 development well located on the Ortoire block onshore in the Republic of Trinidad and Tobago. Touchstone has an 80% operating working interest in the well, with Heritage Petroleum holding the remaining 20%.
The Cas-5 well was spud on 4 June 2025 using Star Valley Drilling Rig #205 and was drilled to a total depth of 7,020 ft over 22 days. Following open-hole logging operations, the well was cased for future production.
The primary target of the Cas-5 well was the Herrera Gr7bc sands, which are prevalent in the Cascadura structure. Cas-5 is the second well drilled into the B block of the Cascadura structure and encountered approximately 620 ft of gross sand. The targeted reservoir intervals were observed approximately 300 ft updip of the Cascadura-2 well, which was drilled in Q1 2024.
The original planned total depth of the well was 6,654 ft. Based on encouraging drill cuttings and mud logging data indicating continued hydrocarbon presence, drilling was extended to 7,020 ft. Wireline logging, mud logging and drill cuttings data collectively suggest that hydrocarbon-bearing sands are present throughout the primary Gr7bc interval.
When funding is available, the drilling rig is expected to be mobilized to complete operations at the nearby Cascadura-4 well, which is currently cased to a depth of 3,200 ft. Cas-4 is also targeting the Herrera sands, with a planned total depth of approximately 6,500 ft.
Upon drilling Cas-4, the Company intends to complete and tie-in Cas-4 and Cas-5 into the Cascadura natural gas facility. All tie-in equipment is currently on location.
