Abstract
Summary The terms auto, natural, and in-situ gas lift all refer to artificial lift systems that use gas from a gas-bearing formation to gas lift a well. The gas lift gas is produced downhole and bled into the production tubing via an auto gas lift valve designed for gas operations. The value of auto gas lift is probably easier to demonstrate than for other types of intelligent well because it provides a direct replacement for conventional gas lift equipment, compressors, and pipelines, and the ancillary equipment they require. An estimated 60 auto gas lift systems have been installed at the time of writing of this paper, most of them in the Scandinavian sector of the North Sea. Several papers have discussed this technology, but so far none has presented a rigorous analysis or solution of the wells' production from a gas lift perspective. This paper presents the basic theory behind auto gas lift and how to apply it. The components of the theory are well known and commonly used in nodal analysis and conventional gas lift design. Properly combining these components enables an auto gas lifted well's performance to be calculated and downhole equipment to be correctly sized and located.
