Case Study
Optimized ESP Solution Reduces NPT >88% in Liquid-Loading Horizontal Gas Well, Russia
CHALLENGE Eliminate lengthy production interruptions due to liquid loading of a well. SOLUTION Stabilize production with a REDA* Maximus* ESP system equipped with REDA Continuum* unconventional extended-life ESP stages and monitored via the Lift IQ* production life cycle management service. RESULTS Reduced time required to unload the well from 3 weeks after every 1 week of production to 3–5 h twice or thrice a week, despite multiple challenges to ESP operation. Liquid loading periodically killed horizontal gas well for 3 weeks A well in Siberia was unable to produce at a steady rate because of liquid loading. The long horizontal wellbore, >500 m [>1,640 ft], leads to gravity separation of gas and liquid—water and gas condensate—phases. The liquids collect in the horizontal sectio
