Touchstone Exploration Inc.（简称“Touchstone”或“公司”）（多伦多证券交易所和伦敦证券交易所代码：TXP）公布了位于特立尼达和多巴哥共和国陆上Ortoire区块的Cascadura-5开发井（简称“Cas-5”）的运营更新。Touchstone拥有该井80%的运营权益，Heritage Petroleum Company Limited持有剩余的20%。Cas

-5井于2025年6月4日开钻，使用Star Valley 205号钻机，历时22天，总深度达7020英尺。在完成裸眼测井作业后，该井已下套管以备后续生产。Cas

-5井的主要目标是Cascadura构造中普遍存在的Herrera Gr7bc砂层。Cas-5是第二口钻入Cascadura构造B区块的井，钻遇了约620英尺厚的粗砂层。目标储层层段位于Cascadura-2井上倾约300英尺处，该井于2024年第一季度钻探。

该井原计划总深度为6,654英尺。由于钻屑和录井数据表明油气持续存在，钻井深度延长至7,020英尺。电缆测井、录井和钻屑数据综合表明，整个主要的Gr7bc层段都存在含油气砂岩。

资金到位后，预计将调动钻机完成附近Cascadura-4井（“Cas-4”）的作业，该井目前已套管至3,200英尺深。Cas-4井也瞄准了Herrera砂岩，计划总深度约为6,500英尺。Cas

-4井钻探完成后，公司计划完成Cas-4和Cas-5井的作业，并将其接入Cascadura天然气设施。所有必要的接入设备目前均已到位。

总裁兼首席执行官Paul R. Baay评论道：
“Cas-5井的钻探按计划按预算完成，尽管目标深度有所延伸，但现场预估成本约为500万美元。我们新钻井团队的出色表现，加上合成油基泥浆和控压钻井的使用，对此次作业的成功至关重要。钻井过程中我们未遇到任何重大问题，这归功于我们针对先前遇到的挑战而实施的改进措施。观测到的油气层段符合甚至超过了我们钻探前的预期，并且随着我们整合正在进行的地震解释数据，这将继续加深我们对Cascadura构造的理解。”

配售更新
公司正在继续评估其与未拨付配售承诺相关的选项，并将尽快发布进一步公告。

Touchstone Exploration Inc. ("Touchstone" or the "Company") (TSX, LSE: TXP) provides an operational update on the Cascadura-5 development well ("Cas-5"), located on the Ortoire block onshore in the Republic of Trinidad and Tobago. Touchstone has an 80 percent operating working interest in the well, with Heritage Petroleum Company Limited holding the remaining 20 percent.

The Cas-5 well was spud on June 4, 2025, using Star Valley Drilling Rig #205 and was drilled to a total depth of 7,020 feet 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 feet of gross sand. The targeted reservoir intervals were observed approximately 300 feet updip of the Cascadura-2 well, which was drilled in the first quarter of 2024.

The original planned total depth of the well was 6,654 feet. Based on encouraging drill cuttings and mud logging data indicating continued hydrocarbon presence, drilling was extended to 7,020 feet. 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 ("Cas-4"), which is currently cased to a depth of 3,200 feet. Cas-4 is also targeting the Herrera sands, with a planned total depth of approximately 6,500 feet.

Upon drilling Cas-4, the Company intends to complete and tie-in Cas-4 and Cas-5 into the Cascadura natural gas facility. All required tie-in equipment is currently on location.

Paul R. Baay, President and Chief Executive Officer, commented:
"Cas-5 was drilled on schedule and on budget, with field-estimated costs of approximately US$5 million, despite extending the target depth. The performance of our new drilling team, along with the use of synthetic oil-based mud and managed pressure drilling, was instrumental in delivering a successful operation. We encountered no material issues during drilling, which we attribute to improvements implemented following previous challenges. The hydrocarbon intervals observed align with or exceed our pre-drill expectations and continue to enhance our understanding of the Cascadura structure as we integrate ongoing seismic interpretation."

Placing update
The Company continues to evaluate its options regarding the unfunded placing commitments and will issue a further announcement as soon as practicable.
