As the development of unconventional reservoirs in North America has increased, hydraulic fracturing operations have evolved. Today, operators are looking for efficiency gains, not just from equipment, but across the entire fracturing value chain to drive down costs, reduce cycle times and improve well performance.

One area that cannot be overlooked is the role played by fracturing fluid systems. Efficiency is driving the demand for innovative fluids that can be tailored to specific well conditions and operating environments. The days of using one completion design on multiple wells is fading, in favor of a customizable approach. The challenge becomes determining which formula works for the wells in a given field.

To test this methodology, a study of completion fluid designs was conducted that compares operations and production across several pads in Gonzales and Lavaca counties, in the Eagle Ford basin. Specifically, the operator was looking for a flexible completion fluid design that would allow field personnel to complete more stages with less shutdowns and screen-outs.

The study found that the use of a tunable friction reducer provides functionality, similar to multiple completion fluid systems, such as slickwater, a high-viscosity friction reducer (HVFR) and linear gel with a single additive, providing operational efficiencies, economic advantages and increased production.
