NCS Multistage announces a record 92-stage completion in the Altares BC Montney Formation, executed using the Multistage Unlimited pinpoint frac system from NCS Multistage. The number of stages reflects the industry’s continued movement toward tighter frac spacing as shown by a 100% increase in stage counts from 2013 to 2016 in the Montney Formation.
The job was completed in a single trip with more than 4100 MT (9 million lb) of proppant placed at an average pumping rate of 3.5 m3 /min (22 bbl/min). Average time per stage was under two hours, with a minimum stage time of just over an hour. The well has a true vertical depth of approximately 2,285 m (7,500 ft) and total measured depth of 5,275m (17,300 ft).
The Multistage Unlimited system combined casing-installed frac sleeves with a coiled-tubing-deployed frac-isolation assembly. During the completion, the assembly was used to locate and open sleeves and simultaneously isolate target zones for single-stage, pinpoint stimulation. Fracs were pumped down the coiled casing annulus.
Don Battenfelder, President of North American Operations for NCS Multistage, stated, “This job illustrates the successful evolution of our tool designs. We continue to make progress in the development of bottom-hole assemblies that facilitate unlimited frac stages in even the most challenging well conditions.”
