AOGCC publishes 2001 annual report; production decline rate slowed to 2%
Petroleum News Alaska Staff
The Alaska Oil and Gas Conservation Commission 2001 annual report is available online. The commission reports that during 2001, Alaska oil and natural gas liquid production was 382 million barrels (an average of 1.05 million barrels per day). Of the total, oil production was some 352 million barrels, NGL production some 30 million barrels.
The decline in liquid production that began in 1989 slowed from a rate of 7 percent in 2000 to 2 percent in 2001.
Produced dry and casinghead gas totaled nearly 3.45 trillion cubic feet, a decrease of 3 percent from 2000. Of that, approximately 86 percent, some 2.96 tcf, was reinjected in enhanced oil recovery projects throughout the state.
Of the 480 billion cubic feet of net gas, 227 bcf was used to fuel oil and gas operations, 8 bcf was flared and 233 bcf was sold, mainly in Southcentral Alaska.
More than 3,500 active wells There were 3,570 active wells in the state at the end of 2001, the commission said, an increase of 141 from 2000, including: 2,371 oil producers, 181 gas producers and 1,018 service wells.
Development and service drilling exceeded 1,457,441 feet in 330 wells on the North Slope and 36 wells in Cook Inlet.
Eighteen new exploration wells began drilling during 2001, 15 on the North Slope and three in Cook Inlet Basin. Comparable figures for 2000 were 11 exploratory wells (seven North Slope, four Cook Inlet). Five of the 2001 North Slope exploratory wells were in the National Petroleum Reserve-Alaska. Total exploratory footage drilled in the state in 2001 was 190,509 feet, 51,686 feet in Cook Inlet and 138,823 feet on the North Slope.
There were also three exploratory wells that began drilling in 2000 and continued into 2001, two in Cook Inlet that were completed as production wells — one oil and one gas — and a third well on the North Slope that was plugged and abandoned.
Wells completed in 2001 included 16 Arctic Slope exploratory wells, seven suspended and nine plugged and abandoned, and four Cook Inlet basin exploration wells, three completed as oil wells and one completed as a gas well.
