HOUSTON, Mar. 31 -- Unocal Corp. subsidiary Northrock Resources Ltd., Calgary, made a hydrocarbon discovery on the Summit Creek prospect in the Central Mackenzie Valley area of the Northwest Territories in Canada.
Tests of the Summit Creek B-44 well confirmed several productive intervals in a gross hydrocarbon column of more than 600 ft. Each of two perforated intervals flowed on test at the rate of 10 MMcfd of natural gas and more than 3,000 b/d of light oil or condensate with flowing wellhead pressures of 900-1,100 psi. One zone also produced 1,000 b/d of water.
Northrock drilled Summit Creek B-44 in January 2004 to 10,053 ft and suspended it until a $16 million completion and testing program during first quarter 2005 (OGJ Online, Area Drilling, Oct. 4, 2004).
The Sah Cho L-71 well, drilled to 12,050 ft TD on a separate structure encountered hydrocarbons but didn't test at commercial rate. The well has been cased to TD and suspended.
The play requires further appraisal. It's 35 miles south-southwest of Tulita and 45 miles from the Enbridge Oil Pipeline and the proposed Mackenzie Valley Gas Pipeline route.
Northrock Resources is operator with a 32.5% working interest in the Summit Creek and Sah Cho prospects. Other interest owners in the Summit Creek well are Husky Oil Operations Ltd., 29.478%; EOG Resources Canada Inc., 26.398%; Pacific Rodera Energy Inc., 6.625%; and International Frontier Resources Corp., 5%.
Partners in the Sah Cho well are Husky, 32.5%; EOG Resources, 23.38%; Pacific Rodera, 6.63%; and International Frontier, 5%.
