The plug was successfully conveyed to depth using a 318 Well Tractor® and then set using a Baker setting tool run below. After the production packer was set, a slickline run, comprising a bottom hole assembly (BHA) dummy string and roller bogies to take the BHA to depth, was run in hole. It soon became apparent that the operation could not be completed successfully using the slickline. Welltec was asked to run the Well Stroker® and Well Tractor together with the slickline retrieval assemblies to fish the junk basket in the first run and the bridge plug on the second run.
The clean-out intervention was completed in 34 days of daylight operations and provided confirmation of the total amounts of sand recovered to surface. The Well Cleaner® PST proved to be an efficient alternative to a conventional coiled tubing unit for this operator who applied the solution for the first time. HSE risks were reduced by applying e-line compared to heavier intervention methods like coiled tubing; less and lighter equipment was involved, fewer lifts were required and mobilization was done considerably faster with Welltec’s solution.
