...., 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...

A tee assembly at the SS 354 riser base would not allow the pig to be received at SS 354 due to low flow and gas bypass in the assembly. Gas flows resumed to full rate...
