The South and East Barrow gas fields lie on the northern extension of Alaska's North Slope, well above the permafrost line and near the Beaufort and Chuckchi Seas. This cold, remote area presents unique production and transportation problems. The reservoir temperature in the South Barrow field is 62/sup 0/F, the East Burrow only 56/sup 0/F; pressure gradients at both fields are about 0.48 lb/ft. Current operating practice limits pressure drawdowns to less than 10% of the reservoir pressure, thus restricting well deliverability. The production string is Arctic-packed, rather than 10% of the reservoir pressure, thus restricting well deliverability. The production string is Arctic-packed, rather than cemented, through the permafrost. As the gas flows up through the subfreezing temperature of the permafrost zone, moisture freezes out and falls to the bottom of the well. The alcohol-lubricated wells are cleaned out twice a month by blowing the accumulated liquids out through the tubing. In 1979, the fields produced 913 million CF of gas at a producing cost of $1.36/1000 CF.
