Setting multiple balanced plugs in one run using CST as base
Share this case study:
A major operator in the North Sea successfully plugged and abandoned a well with 6 separate cement plugs in one run using the Cement Support Tool (CST) as base for each plug. All plugs were set in 8 ½” open hole @ 90° deviation from 5 200 m MD to 3 035 m MD. The last plug was tagged with 10 ton weight on bit at planned depth.
