Record 92-sleeve fracturing operation completed in Eagle Ford

Posted on 30 May 2014

NCS Energy Services, an independent technology and services company specializing in multistage completions, has announced the completion of fracturing operations on an Eagle Ford well that incorporated 92 Multistage Unlimited cemented casing sleeves. This is a world record number of sleeves in a single completion, according to the company.

NCS teamed with a coiled-tubing and frac-pumping service company to perform the frac operations using the NCS Multistage Unlimited resettable frac-isolation system deployed on coiled tubing. The system required no frac plugs to pump down and no balls to drop. At one point, the company stated, 20 stages were completed in 24 hours, and many stages were completed in less than one hour per stage. The NCS frac-isolation assembly completed the final 80 stages in a single trip. Overall, almost 6 million lb of proppant were placed in precisely positioned fracs.

“Everyone was very pleased with the performance of the Multistage Unlimited equipment,” said Tim Willems, NCS President, US and International. “All 92 sleeves opened as designed, and at the end of the job, after locating, isolating and shifting 80 consecutive sleeves for fracking, the isolation assembly looked as good as new. We’re confident that it can handle many more stages than that without tripping out of the hole.”

The NCS Multistage Unlimited system was introduced in 2011; since then, more than 40,000 cemented casing sleeves have been installed and fracked.
