Just came across this post so thought I would share but really don’t understand it and unsure whether it has any current relevance. It was posted only a day or so ago.
Gas was recently discovered at Touchstone Exploration Inc. COHO-1 exploration well in Tableland, Trinidad. This gas will be commercialized through a 2.5km 6inch pipeline to an existing facility.
The COHO structure is a SE folded, northerly backthrusted, SW plunging anticline at the Mid Miocene stratigraphic level. This fold occurs immediately south of the prolific Barrackpore anticline. The COHO structure climbs to the NE where Mid Miocene rocks are then downthrown 2000ft to the E by a tear fault, placing the Mid Miocene Herrera sands juxtapose to Late Miocene Lower Cruse sealing clays.
The syn-kinematic deepwater Herrera turbidite sands attain 2200ft gross interval as sands thicken south of the Barrackpore trend into the axis of the foredeep at Mid Miocene time.
The folding of the COHO structure occurred between Late Mid Miocene to Late Miocene as noted in the thinning of the Karamat interval atop the COHO anticline compared to the N & S flanks.
The COHO-1 exploration well was spud on 7th August 2019 and reached TD of 8560ft in 28 days. 105ft of net gas pay was measured between 5486ft & 7240ft. Logging also identified the presence of 100ft of oil sands in a previously untested thrust sheet. The well tested dry natural gas with peak rates of 19.8mmcfd (3300boepd).
