Paper presented at the SPE/ICoTA Well Intervention Conference and Exhibition, March 24–25, 2020
Paper Number: SPE-199858-MS
... Abstract Suez Oil Company in Egypt encountered well integrity issues due to a suspected leak in a 3 ½-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...

... associated with conventional plug operations. The plug and electric manipulation tool (EMT) was run on wireline in a deviated production well with gas lift and set at three different depths to verify the location of a leak and elimate that the leak was in the one of the side pocket mandrels (SPM). All of...
