Fracturing Systems

Optimize Your Completion Design

NCS Multistage offers innovative, patented fracturing systems for both single-point and multi-stage completions throughout the world.

NCS Multistage offers a systematic approach that allows you to make well-to-well comparisons with confidence and optimize a pinpoint completion design for any given field or formation.

We provide consistent, repeatable frac delivery in addition to measured downhole data that helps you to better understand the formation, the well, and the stimulation.

Unlike conventional methods, our pinpoint fracturing solutions enable you to know how many entry points are created, their precise location, and exactly how much proppant is placed into each stage.

Pinpoint Optimization Benefits

Pinpoint fracs are predictable, reliable and repeatable

With the Multistage Unlimited® pinpoint-frac system, you know where fracs initiate and exactly how much proppant you put into each one. No matter what else you adjust (frac spacing, frac dimensions, proppant type, proppant concentration, frac fluid or injection rates) you can evaluate the effects of those design changes because frac placement is repeatable from well to well.

Recorded downhole data describes every frac

At every stage, the Multistage Unlimited® frac-isolation-asssembly records actual pressures and temperatures at the frac zone and in the wellbore below. Two proprietary, high resolution data recorders measure and record pressure, temperature, and forces acting on the tool string during a completion. Stage-by-stage details provide data and insights you can’t get with other conventional methods.

Use actual bottom-hole pressures to improve frac modeling

Actual pressures at the frac zone (no pipe friction guesswork) permit more exact pressure history matching, enabling more realistic frac modeling and reservoir stimulation.

One Source. Many Solutions.

NCS Multistage offers a variety of solutions for your next frac job including sleeves, isolation assemblies, well strokers and refrac assemblies.

Innovus™ Well Stroker
Fracturing Systems

When Innovus™ Convertible sleeves are utilized in a wellbore, this is the BHA required to manipulate the injection barrel. This converts the sleeve into the regulated water-injection mode.
