为了测试Cascadura天然气发现以南大约1英里的构造地层，Chinook-1勘探井钻井总深度达到了10039英尺。根据试金石勘探公司的电缆测井结果显示，在赫雷拉砂岩地层的3个独特的逆断岩床中钻遇了总厚度大约589净英尺的“重大”天然气生产层，而在较浅的Cruse地层中，发现井还钻遇了大约20净英尺厚的额外天然气生产层。
Chinook-1井是试金石勘探公司在Ortoire勘探区块钻取的第3口勘探井，也是自2019年8月Ortoire勘探钻井计划开始实施以来获得的第3个油气发现。
试金石勘探公司总裁兼首席执行官Paul R Baay在一份公司声明中表示，Chinook-1勘探井的钻井结果远远超出了钻前的预期。”

原文如下： Touchstone Announces Significant Gas Discovery
Touchstone Exploration Inc.has announced a “significant” natural gas discovery at the Chinook-1 exploration well on the Ortoire exploration block, onshore in the Republic of Trinidad and Tobago.
Chinook-1 was drilled to a total depth of 10,039 feet to test a structural formation around a mile south of the Cascadura gas discovery. Wireline logs indicated “significant” natural gas pay totaling approximately 589 net feet in three unique thrust sheets in the Herrera sands, according to Touchstone, which added that additional natural gas pay of approximately 20 net feet was encountered in the shallower Cruse formation.
Chinook-1 is the company’s third exploration well drilled on the Ortoire exploration block and the third hydrocarbon discovery since commencing the Ortoire exploration drilling program in August 2019.
“The results from the Chinook well exceeded pre-drill expectations,” Paul R. Baay, the president and chief executive officer of Touchstone, said in a company statement.
