Background
An operator had traditionally run wireline perforating to achieve the depth accuracy required for their fracturing operations. Because CT is used to clean out the oil and gas producer after fracturing, a significant amount of time was needed to rig down and rig up surface control equipment, which resulted in additional costs and HSE risk. The ABRASIJET* hydraulic pipe-cutting and perforating service was used on a small offshore platform to perform the perforations and limit the requirement of swapping services and equipment.
