... that involves injecting high-pressure gas from the casing into the tubing via gaslift valves. Gaslift mandrel spacing design frequently contains several challenges However, by regularly monitoring well operating condition at the surface, compared to the conventional costly wireline FGS data points...

.... Presence of shallow gas zone gave an opportunity for utilizing as auto gas lifting to revive the shut well. Considering unavailability of gas lift mandrel across the gas zone, innovative approach was needed. The well was modelled for gas lifting and accordingly the conventional jet pump was selected...

.... The upper valve added value by allowing the production tubing, which included gas lift mandrels, to be pressure tested to full working pressure before setting the production packer. The lower valve facilitated circulating the well to underbalance fluid before setting the production packer and then allowed...
