HOUSTON, Dec. 3 -- Corridor Resources Inc., Halifax, NS, plans to appraise an oil discovery 3 km southeast of its McCully gas field in southern New Brunswick.
The South Branch G-36 well flowed clean, 45° gravity oil at the rate of 59 b/d without water through production tubing after 10 days' clean-up of frac fluid.
Producing interval is the Hiram Brook member of the Mississippian Albert formation at 1,574-1,612 m. The frac job placed 30 tonnes of proppant before being prematurely ended due to a frozen water line, which Corridor said may have reduced the frac's effectiveness. A pump will be installed for long-term test.
Corridor also ran a frac in Hiram Brook at 1,757-1,840.5 m, resulting in a show of oil and no measurable gas. This interval is considered tight, but another 31 m of potential oil pay previously reported as gas pay in the Upper Hiram Brook have not yet been completed.
TD is 2,642 m, nearly 500 m into the Fredrick Brook shale.
The well is on the southern flank of the Elgin subbasin, where Corridor recently completed a $2.5 million 3D seismic program around the well. After interpreting the new seismic, the company will drill an offset in early 2009 to G-36, named Caledonia field in recognition of the southern bounding basement rocks of the Caledonia highlands.
Meanwhile, Corridor expects to achieve 2008 yearend production of 35-40 MMscfd of gas from McCully field depending on results of clean-up at the J-47 well and the outcome of a multistage frac at the I-47 horizontal well.
In the Elgin area 20 km east of McCully field, Corridor has drilled Green Road G-41 to 1,118 m and run intermediate casing before deepening to core and run two fracs in the Frederick Brook shale. It is drilling Mapleton N-11 to core a full section of the shale.
