作为其天然气开发计划的一部分，Touchstone Exploration 正在特立尼达岛陆上中央区块钻探 Carapal Ridge-3 开发井 (CR-3)，这是该气田近二十年来的第一口井。

Touchstone 持有 CR-3 井 65% 的作业权益，Heritage Limited 持有剩余的 35%。该井于 2025 年 11 月 23 日开钻，使用 Star Valley 205 号钻机，历时 35 天钻至约 8,200 英尺的总深度。

CR-3井钻遇了厚达1082英尺的净砂层，其中包括约1000英尺的埃雷拉砂层。测井、泥浆录井和钻井数据表明，埃雷拉层段内均存在含油气砂层。该井还在卡拉马特组发现了第二个含气层，目前正在评估其未来钻探潜力。

完工作业正在进行中，预计将于 2026 年第一季度与中央区块天然气处理厂连接。连接后不久即可开始初步生产。

Touchstone Exploration is drilling the Carapal Ridge-3 development well (CR-3) on the Central block onshore in Trinidad as part of its natural gas development program, marking the first well in this pool in nearly two decades.

Touchstone holds a 65% operating working interest in CR-3, with Heritage Limited holding the remaining 35%. The well was spud on 23 November 2025 using Star Valley drilling rig #205 and drilled to a total depth of about 8,200 ft over 35 days.

CR-3 encountered a substantial 1,082 ft of net sand, including around 1,000 ft of Herrera sand, with wireline, mud logging and drilling data indicating hydrocarbon-bearing sands throughout the Herrera interval. The well also established a second gas-charged play in the Karamat formation, which is being evaluated for potential future drilling.

Completion operations are underway, and tie-in to the Central block natural gas processing facility is targeted for the first quarter of 2026. Initial production is expected to begin shortly after tie-in.
