HOUSTON, Sept. 21
-- Delta Petroleum Corp., Denver, said its plans for further drilling in the southern Columbia River basin in Washington state have been placed on hold until the company reviews completion and test information from the Gray 31-23 well, where tests have proved noncommercial thus far.

Delta perforated and tested the majority of the prospective zones in the Gray well at 11,580-12,280 ft.

“The six lowermost zones demonstrated high pressures as expected, but have flowed only fresh water to date. The zones located further uphole have flowed a combination of water and gas; however, the gas volumes have been minimal and substantially below precompletion expectations deeming these intervals uneconomic,” the company said.

More tests are planned in the basalt section on intervals that had gas shows during drilling.

Delta and Husky Energy Ltd. hold 50-50 interests in 424,000 net undeveloped acres in the basin.
