World's first controlled, pinpoint refrac enabled by NCS Multistage system Houston, July19, 2016—NCS Multistage has announced the successful refrac of a 25-stage well that had originally been completed utilizing the company's Multistage Unlimited coiled-tubing frac system and MultiCycle frac sleeves, which gave the operator the ability to manage stage-by-stage formation access over the life of the well. After evaluating production, the operator wished to increase stimulated reservoir volume by placing additional proppant in all stages, using a different fluid system and higher pump rates than used in the original completion. The refrac began by closing all of the sleeves and verifying wellbore pressure integrity. Then, using the NCS Shift-Frac-Close sequence, all 25 stages were individually refractured. At each stage, the MultiCycle sleeve was opened for the frac and then immediately closed at the end of pumping. When the stimulation was complete, the full-drift wellbore was again successfully pressure tested, all sleeves were reopened, and the well was turned over to production. The entire refrac took approximately 36 operating hours, and wellbore pressure and formation access were controlled throughout the operation. Marty Stromquist, NCS Multistage Chief Executive Officer stated, "NCS always strives to deliver systems that give operators maximum flexibility in how they design their well stimulations. This job demonstrates how MultiCycle sleeves enable refracs with less operational risk compared with traditional completions and eliminate the complexities of dealing with pre-existing well configurations. MultiCycle sleeve completions are giving operators new flexibility to manage production, perform well remediation, and to refracture while maintaining wellbore pressure integrity."
