NCS Energy Services has reported the successful completion of two horizontal Cardium wells, employing a first-time combination of high-rate slickwater and the multistage unlimited fracturing system.
The company placed more than 60 frac stages in one well, with aggressive spacing of individual fracture stages.
Eric Schmelzl, VP of Strategic Business for NCS Energy Services, commented: "We continue to be pleased with the success we are seeing as we push the envelope of multistage completions. This successful combination of the Multistage Unlimited system with high-rate slickwater opens new avenues for bringing precision and predictability to unconventional completions."
Treating rates of 49 bbl/min (7.8m3/min) enabled placement of 40 frac stages in a single 24-hour period, making tightly spaced fractures a viable and economical alternative to less precise and unpredictable stimulation methods. Cemented NCS GripShiftcasing sleeves provided fast and reliable formation access, and subsequent analysis of downhole gauge data identified any hydraulic communication between frac stages.
Calfrac Well Services provided the field execution of the new marriage of slickwater technology with high-density pinpoint fracture placement, believed to be an industry first in the evolution of multistage completion technology.
