Touchstone Exploration announce Carapal Ridge-3 Drilling Results

08 Jan Touchstone Exploration announce Carapal Ridge-3 Drilling Results

(Oilandgaspress) Touchstone Exploration Inc. provides an operational update on the Carapal Ridge-3 development well (“CR-3”), located on the Central block onshore in the Republic of Trinidad and Tobago. Touchstone holds a 65 percent operating working interest in the well, with Heritage Petroleum Company Limited holding the remaining 35 percent.

Highlights

• CR-3 is the first well drilled into the Carapal Ridge pool in the past 17 years and encountered
  approximately 1,082 feet of net sand, including approximately 1,000 feet of net Herrera sand.
• Open-hole wireline logging, mud logging, and drilling data collectively indicate the presence of
  hydrocarbon-bearing sands throughout the Herrera interval.
• The well encountered a thick pay zone across multiple Herrera horizons, both above and below a shale marker.
• Completion operations are underway, with tie-in to the Central block natural gas processing facility
  targeted for the first quarter of 2026.
• The well results support the potential for up to three additional Herrera development wells on the Central
  block.
• CR-3 also established a second, uphole, gas-charged play in the Karamat formation, which is being
  evaluated as a stand-alone prospect for potential drilling.
  The CR-3 well was spud on November 23, 2025, using Star Valley Drilling Rig #205 and was drilled to a total depth of 8,200 feet over a 35-day period. Following open-hole logging operations, the well was cased for future production. Based on initial field-level cost estimates, the well was approximately 25 percent over budget and did not require any sidetrack operations. The additional time and costs were primarily attributable to efforts required to control natural gas flows from the Karamat sands, which have not previously been produced on the Central block.

The primary target of the CR-3 well was the Herrera sands, which are prevalent within the Carapal Ridge
pool. CR-3 is the first well drilled into the Carapal Ridge pool in the past 17 years and encountered
approximately 1,000 feet of net Herrera sand. The well targeted Herrera sands within the developed
reservoir section currently on production above a 30-foot shale marker, as well as unproduced Herrera
sands below the shale marker. The lower sands were previously completed and tested, but not produced,
by a prior operator in the offsetting Carapal Ridge-1 well.

These completion tests, known as tests 4, 5 and 6, flow tested at combined peak average daily test rates of over 20 million cubic feet of natural gas and 500 barrels of condensate for periods of approximately one to two days. CR-3 encountered approximately 635 feet of net sand in the developed Herrera reservoir at depths between 6,930 feet and 7,770 feet above the shale marker and approximately 365 feet of net Herrera sand below the shale marker within the unproduced reservoir at depths between 7,770 feet and 8,200 feet.

Although drilling was terminated at 8,200 feet, the well remained within clean sand at total depth. In addition to the Herrera sands, approximately 82 feet of net Karamat sands were also encountered directly above the Herrara formation at depths between 6,530 feet and 6,760 feet. These Karamat sands are also present in the Carapal Ridge-1 and Carapal Ridge-2 wells.
