NCS Energy Services has developed Multistage Unlimited technology as a more efficient, more economical alternative to plug-and-perf and ball-sleeve frac systems, both of which bullhead fluids down the casing, with no feedback about formation response at the frac zone, no recourse in the event of a screen-out, and no way to manage water and chemical consumption. Both methods do, however, have a big appetite for pumping horsepower.
In developing Multistage Unlimited technology, NCS faced two challenges: 1) Overcome the limitations of one-way fluid movement; and 2) Find a more efficient way to isolate each stage during completion. NCS overcame both challenges by adopting CT to operate the frac-isolation system, and to open the company’s grip/shift sliding sleeves.
