Throughout the life of a well, it may be necessary to isolate existing perforations for the purpose of re-completing an alternative section of the wellbore or to prevent water from being produced.
Throughout the life of a well, it may be necessary to isolate existing perforations for the purpose of re-completing an alternative section of the wellbore or to prevent water from being produced.
Traditional methods may involve setting a plug, straddling the perforations or performing a chemical or cement squeeze, all of which can be complex and costly and in the case of a straddle, result in a reduced ID wellbore. To address this challenge, TAQA has developed ZoneStop, a cost effective, low complexity, patent protected method that isolates existing perforations and allows water shut off or re-completion to occur. ZoneStop uses TAQA’s patented, field proven swelling elastomer technology
