75% Increase in Gas Injection Depth Optimizes Oil Production in Extended-Reach Wells, North Sea

Publication Date: 12/11/2017

Extended-reach wells presented a challenge to the use of gas lift in the North Sea. The smaller liner sizes used at greater depths limit mandrel and gas lift valve diameters. Moreover, at high inclinations, the use of slickline for changing out valves becomes more problematic. CT and electric line tractors provide a solution but increase intervention costs. Setting the valve higher up the well where the inclination is smaller would facilitate slickline usage but result in suboptimal production.
