...Gas Lift Concept Design In terms of delivering gas lift to the riser base, several different technical solutions have been employed in deep water subsea projects. A conventional solution is to deliver the lift gas through a dedicated riser. The gas lift riser typically ties into a dedicated...

... characterization is performed to match the stock tank oil density, Gas-Oil Ratio, and water cut. In the second section, field trial results are presented. Since in WA field lift gas is applied at riser base, the combined effect of foamer and lift gas is studied next. In the third section, lab tests are conducted...

...., fax 01-972-952-9435. Abstract Riser base gas-lift is one of several methods that have been proven to work in subsea developments for production enhancement. In addition, gas-lift can be used as an effective method to suppress severe slugging that usually occurs in flowlines with downhill inclination...
