NCS places record 60 stages in a single Torquay formation well with half-straddle technology
CALGARY -- NCS Oilfield Services has announced the successful placement of 60 stages in a single well completion, using its Multistage Unlimited system. The project marks a new record for the company by completing its largest number of stages for a single wellbore in Canada.
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 of 18,782 ft and a true vertical depth 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. 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,” said Eric Schmelzl, NCS vice president of Strategic Business.
