Unocal's Canadian subsidiary, Northrock Resources Ltd., has made a hydrocarbon discovery on the Summit Creek prospect in the Central Mackenzie Valley area of the Northwest Territories in Canada.

Northrock Resources recently concluded this winter's program which was comprised of completing and testing the Summit Creek B-44 discovery well and drilling an exploration well, Sah Cho L-71, to test a separate structural closure.

The Summit Creek B-44 well spud on Jan. 16, 2004, and was drilled to a depth of 10,053 feet in 63 days. The well was suspended in late March 2004 with a completion and testing program planned for January through March 2005.

Testing of the Summit Creek B-44 well confirmed several productive intervals within a gross hydrocarbon column of over 600 feet. Two separate intervals were successfully perforated and flow tested for periods of 18 and 39 hours respectively. Each zone produced at rates of approximately 10 million cubic feet per day (mmcfd) of natural gas and more than 3,000 barrels per day (bpd) of light volatile oil or condensate with flowing well head pressures of 900 -1,100 psi. One of the zones also produced approximately 1,000 bpd of water.

The Sah Cho L-71 well spud Jan. 21, 2005, and was drilled to a total depth of 12,050 feet in 43 days. Hydrocarbons were encountered at L-1; however, open hole testing did not establish commercial flow rates. The well was cased to TD and has been suspended.

"While the results of this winter's program are encouraging, additional work will be necessary to assess the commercial viability of this emerging play," said David Pearce, Northrock's president.

The program area is located about 35 miles south-southwest of the town of Tulita and 45 miles from the existing Enbridge Oil Pipeline and the proposed Mackenzie Valley Gas Pipeline route.
