Corridor Resources reports that well stimulation (fraccing), initial flow-back testing and initial well clean-up operations have been conducted at the McCully J-67 well in the McCully natural gas field located near Sussex, New Brunswick. The J-67 well flowed at a measured rate of 0.76 million standard cubic feet per day (mmscf/d) and a flowing wellhead pressure of 555 pounds per square inch (psi) at the end of a 40 hour flow period. The well was flowed through a 7.94 millimeter choke and recovered approximately 30% of injected completion fluids during the test period (i.e. 394 of 1316 cubic meters of injected completion fluids). The well was flowed through casing and was still flowing back significant volumes of completion fluids at the end of the relatively short initial flow-back period. The well was then re-entered with a coiled tubing string, encountering sand fill in the casing approximately 50 meters above the highest set of perforations. During this coiled tubing operation, the sand plug and two flow-thru bridge plugs separating the three intervals fracced in this well (two in the "B" sand and one in the "A" sand) were drilled out. Consequently, Corridor does not believe that the initial test results are indicative of the true initial flow potential of the well. A production tubing string will be run in the well prior to a combined production test of the three fracced intervals. Corridor will release the flow rates from the production test once they become available, expected to be on or about September 23. Potash Corporation of Saskatchewan and Corridor are joint participants in the J-67 well.
J-67 is the 4th well to be fracced and tested as part of the current multi-well completion program being conducted during August and September. Based on log evaluations and sidewall core analyses, the J-67 well is interpreted to have thinner and less permeable pay sections than the initial three wells (M-66, K-66 and J-66) which were fracced and tested in August. Corridor anticipates that flow rates for the J-67 well will improve materially on re-test through a production tubing string once the wellbore has been cleaned out. This expectation is further supported by experience in both the D-48 and J-65 wells, where production rates on re-test increased significantly from initial clean-up rates following periods of shut-in production.
