The client needed to isolate a troublesome parted collar section at 11,068 ft [3,373m] in a 5.5in #23 lbs/ft casing. Since the client had already planned to fracture the well, they needed to regain as much of initial casing integrity possible. They first performed a remedial cementing job to act both as a barrier and a receptacle, to support a further stainless steel high-pressure inner-lining solution. The client finally selected Saltel expandable steel Patch.
