Touchstone Exploration Inc. provided an update regarding exploration operations on the Ortoire block, onshore Trinidad and Tobago (Touchstone 80% working interest operator, Heritage Petroleum Company Limited 20% working interest). Touchstone is currently evaluating the third formation test at Chinook-1, having completed the overthrust Herrera sheet in the well on March 25, 2021, perforating 115 feet of the formation at depths between 8,320 and 8,435 feet. The well accumulated pressure to 2,100 psi at surface immediately after being completed, and flow back testing commenced on March 27, 2021. The well recovered load fluid with minor amounts of 35 degree API gravity oil and formation water. Low flow back rates indicate that an artificial lift is required to determine the wells' production potential. By putting the well on pump, the Company can evaluate the deliverability of the zone and assess possible formation damage that may have occurred during drilling. Touchstone will commence installation of the pumping assembly when the service rig has completed current operations at Cascadura Deep-1. Testing to date indicates the Chinook-1 well is in an oil window of the Herrera fairway. Over the course of the next few months, the Company will form a development plan for the oil encountered in the exploration well with the focus on identifying locations in the intermediate and overthrust Herrera sand sheets. Oil production from the Herrera thrust sheets is common in Trinidad along the Herrera fairway. Following the extended oil test, the Company may complete an uphole shallow gas interval in the Cruse formation or test a Karamat shale gas prospect that was encountered while drilling. The Company is currently preparing to perforate the lowermost section of the shallow overthrust Herrera sand in Cascadura Deep-1. After the interval has been perforated, the Company expects to perform a three-day flow back test followed by a minimum two-week built-up test. Well test results will be disclosed upon completion. The Company completed testing a low resistivity zone in the intermediate thrust sheet that showed elevated gas readings during drilling. While indications of hydrocarbons were apparent while drilling through this secondary interval, wireline logs indicated low resistivity prompting the Company to test the interval to gain a further understanding of reservoir characteristics. The primary purpose of the test was to correlate reservoir salinities with wireline log responses to define pay intervals during potential development of the Cascadura Deep-1 structure. As expected, based upon the low resistivity readings, the tested interval yielded predominantly water with minor amounts of hydrocarbon emulsion and was subsequently abandoned.
