Drilling Activity Details
Trinidad & Tobago
Drilling Activity Summary
Description
Touchstone Exploration’s first exploration well in Trinidad’s Ortoire Exploration Block has encountered four zones with prospective gas accumulations. According to the company, the onshore exploration well, #1-Coho, was drilled to 8,560 ft, and well logging indicates four gas-bearing packages in the Herrera member of the Mid-Miocene-aged Cipero Formation. Two sand packages with approximately 64 ft of net gas pay were encountered in Upper Herrera Gr7b section between 5,486 and 5,782 ft. The Gr7b Sand packages were similar to results in offsetting #1-Corosan, where similar sands tested flowing about 8 MMcf per day. Wireline logging also indicated two prospective gas sand pack-ages in the Herrera Gr7c section between 6,530 and 7,240 ft. The two sand packages contain a combined 41 ft of probable net gas pay which was not tested. In addition, logging identified the presence of oil sands in Lower Herrera Gr7b repeat section at 7,788 ft, and the lower quality, 100-ft thick gross interval does not currently appear to be commercially prospective. The rig will be move to drill #1-Cascadura, which is the second of four initial exploration wells the company plans to drill on the block. Touchstone is based in Calgary.
