The toolstring encompassed the Well Cleaner PST HV and three bailer sections to capture and recover the debris(sludge) to surface. The Well Cleaner PST HV was run in hole and tagged the obstruction at 5,988 ft. (1,825 m), then pulled back to 5,971 ft. (1,820 m) where it started the clean-out operation. Slowly moving forward the Well Cleaner PST HV cleaned down to and around the fishing neck. At surface it was verified that the bailers had recovered ~ 55 lbs of heavy mud from the well. The fishing neck was now accessible for the plug pulling operation to continue.
The operator was fully satisfied with the performance of the Well Cleaner and their objective was met successfully. Using Welltec’s e-line, clean-out solution prevented the need to bring in a coiled tubing unit, which saved at least five days.
