NCS Oilfield Services, an independent technology and services company specializing in multistage completions, has successfully completed placement of 60 stages in a single well completion, once again demonstrating the reliability of its Multistage Unlimited system. The July project marks a new 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 multi-stage 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 (TMD) of 5,725 m (18,782 ft) and a true vertical depth (TVD) of 2401 m (7,877 ft), using 59 NCS frac sleeves and one abrasive cut. Sixteen sandoffs were successfully 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,” Schmelzl added. “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.”
NCS Oilfield Services currently offers its Multistage Unlimited systems in Canada, the US, Australia, Russia, Argentina and China. The company has a record of more than 3,000 multistage completions, successfully placing over 470,000 tonnes of proppant. The company’s proprietary Multistage Unlimited technology eliminates perforating, plugs, balls and baffles, and incorporates coiled tubing to deliver advantages not available from ordinary methods.
