Great Bear Petroleum’s first North Slope test well, the Alcor No. 1, has almost reached the HRZ oil source rock, the first of the source rocks from which the company wants to obtain core samples, Pat Galvin, Great Bear’s vice president of external affairs, told Petroleum News July 9.
“We’re in progress moving towards our first zone for coring,” Galvin said, adding that the coring should be done within the next few days.
The near vertical well will eventually penetrate and sample all three of the major North Slope source rocks — the HRZ/GRZ, the Kingak and the Shublik — before bottoming out at a depth of over 11,000 feet. Great Bear will send samples from the cores to laboratories for testing, to determine the production characteristics of the rocks.
Great Bear is pioneering the possibility of oil production on the North Slope using the fracking techniques in source rocks that have proved so successful elsewhere in North America.
