Diagnose and Remediate Leak on Constrained Operating Conditions BringsBack to Production Important Gas Well in Egypt Delta Region

摘要

Suez Oil Company in Egypt encountered well integrity issues due to a suspected leak in a 3 1/2-in completion,in a gas well in Desouq,Nile Delta Region.This led to well closure and consequent loss of production.(figure 1)The memory multi-finger caliper was showing pitting but was not conclusive on identifyingthe leak point.Suez Oil Company required a rig-less solution to diagnose and pinpoint the leak andrepair the well,so production could resume.(figure 2)However,conducting well intervention techniqueson conventional slickline could not provide precise depth placement,much less real-time control andmonitoring capabilities to confirm operations.Production logging services were deployed on E-line to detectthe leak point in the tubing in real time by the variation of the quartz gauge's pressure and temperaturemeasurements and spinner rotation associated with the flow.Once the Leak point was properly identified,Straddle system was deployed to remediate the leak,utilizing digital slickline,and the well was placed backinto production.
