... as straddle gas lift valve and installed across the gas zone SSD. This achieved controlled gas rate resulting in successful well revival at rates ~ 800 bopd, 1.1 mmscfd gas and 1000 bwpd. Post revival, the well produced at stable parameters for more than a year after which it started showing cyclic behavior...

... Abstract Control lines hydraulically operated downhole isolation valves were run with the production casing strings of big bore offshore gas producers to provide downhole isolation for losses and pressurised mud cap drilling (PMCD) operations. The mandrel casing hanger was re-designed...

... flow controller to include an additional algorithm for slug suppression at the riser top choke valve. This simple addition eliminates the requirement of active operators’ intervention in the event of slugging, as well as reducing the frequency of process trips. In comparison with other slug control...
