Touchstone Exploration indicated that after the second stage of testing at the Cascadura 1ST1 well, the tests deliver a combined average of 10,600 boe/d.
According to President and CEO Paul Baay, "This second test, focusing on the upper 345 feet of pay, confirms the material size of the discovery at Cascadura and the vast opportunity that exists on our Ortoire property. In addition to estimated production at our Coho discovery and our existing production, this well gives us a clear path to 10,000 boe/d with an estimated 75% natural gas and 25% liquids product mix. With domestic demand for natural gas exceeding current production, Touchstone is working with industry partners to bring these new volumes on-stream as quickly as possible. With the Cascadura well only three kilometres from existing infrastructure, we are evaluating the most efficient path forward to tie these significant volumes into the domestic sales network."
The Cascadura well is located in the Ortoire exploration block, onshore Trinidad and Tobago (Touchstone 80% working interest operator, Heritage Petroleum Company Limited 20% working interest).
It has previously been reported that testing from the well indicated the presence of gas rich liquids at Cascadura 1ST1.
In addition, James Shipka, Chief Operating Officer said "Based upon the results of our initial test, the second stage of testing at Cascadura was in line with our expectations. Similar to the first test, production testing was constrained by the third-party surface equipment which limited us to a 40/64" choke. This resulted in natural gas flow rates similar to what was observed initially, although at a much lower surface drawdown. The flowing pressures and the associated pressure drawdown exceeded our expectations, suggesting that the sands evaluated during the second stage of testing are of exceptional quality and significant resource size. For comparison, in the lower sands we achieved a flow rate of 26.8 MMcf/d at a reservoir drawdown of 20% with 691 bbls/d of associated liquids. In the upper sands, we achieved a slightly higher flow rate of 28.2 MMcf/d at a reservoir drawdown of only 13%, with over 800 bbls/d of liquids. Based on these test rates, we are modelling initial production rates of between 40 and 50 MMcf/d with approximately 1,100 to 1,400 bbls/d of natural gas liquids, which would yield approximately 6,200 to 7,800 boe/d (net) to the Company."
Touchstone also provided an update on the Coho-1 gas discovery. According to the company, they have completed surveying the pipeline required to tie-in the Coho-1 dry natural gas discovery and is currently awaiting local contract bids for construction.
The pipeline has been specified to allow for production rates of up to 20 MMcf/d to accommodate the expected volumes from Coho-1 and potential future locations. The Company anticipates having the Coho-1 well on production early in the third quarter of 2020.
