Greater Ekofisk apparently has the most severe corrosion conditions down hole of the North Sea oil fields now in production. Tubing failures, due to CO/sub 2/ corrosion and erosion, have been occurring since 1978. Many of the failures have occurred in production conditions previously considered noncorrosive. Three case histories describing different modes of corrosion are presented. Phillips Petroleum Co. Norway established a corrosion task force to find the best methods to control the corrosion. The methods were evaluated using a combination of surface corrosion monitoring, tubing caliper surveys, and inspection of recovered tubing. The economics of the different treating methods utilized are reviewed. A cost-effective approach to the monitoring and chemical treating of CO/sub 2/ corrosion conditions in offshore production operations is presented.
