60 stages placed in Canadian single well completion

Posted on 25 July 2013

NCS Oilfield Services has announced the placement of 60 stages in a single well completion using its Multistage Unlimited. The July project marks a record for the company by completing its largest number of stages for a single wellbore in Canada.

“Our goal is to help operators accelerate time to production as efficiently and effectively as possible,” said Eric Schmelzl, NCS vice president of strategic business. “A successful multistage completion like this 60-stage operation is a win-win for our clients, their investors and the industry as a whole.”

The multistage completion was accomplished on a 4.5-in. cemented lateral targeting the Torquay formation. Using the NCS Half-Straddle option that pumps frac volumes down the coiled tubing, the job placed 639.5 tonnes of proppant in 120 hours. The completion operation reached a total measured depth of 5,725 meters (18,782 ft) and a true vertical depth of 2401 meters (7,877 ft), using 59 NCS frac sleeves and one abrasive cut. Sixteen sandoffs were circulated clean without incident or significant lost time.

“The Multistage Unlimited Half-Straddle option offers operators a highly efficient technique that reduces the overall job time, as well as fluid requirements. The method often eliminates the need for a high-pressure frac tree, because the coiled tubing contains the treatment friction pressures, isolating that component of the treating pressure from the wellhead equipment,” Mr Schmelzl said.
