Friction Reducers

Friction Reducers

As a key component in slickwater applications, traditional emulsion-based friction reducers have long been a mainstay of the North American completions market.

Friction reducers are intended to reduce the friction in the wellbore during the drilling and stimulation processes in unconventional reservoirs such as coal beds and shales. The large volumes of water pumped, and high rates required, result in high friction pressures from turbulent fluid flow. Cationic or anionic friction reducers reduce turbulence and minimize friction losses.

However, these polyacrylamide-based liquid invert emulsions (friction reducers) are limited by poor water quality tolerance, limited proppant carrying capacity, and escalating costs. Until now.

HiRate™ High Efficiency Friction Reducers (HEFRs)

Innospec Oilfield Services offers a wide range of proprietary formula liquid or dry friction reducers specifically designed for the unconventional challenges that face many clients today: to deliver lower pumping pressures using less product in less time.

Proven superior performance in slickwater fracturing.
Since 2015, Innospec Oilfield Services has focused on emulsion chemistry, with a goal of having its application deliver far more than mere reduced friction. Today, Innospec’s extensive portfolio of HiRate™ High Efficiency Friction Reducers (HEFR) successfully meet a myriad of customer needs with industry-leading features and benefits, including:

  • Less product per stage
  • Superior friction reduction
  • Ultra-fast inversion
  • Significant cost savings
  • Brine tolerant formulations
  • Operational simplicity
  • Reduced and stabilized treating pressures throughout formation
  • Smaller onsite footprint
  • Better sand transport
  • Aggressive sand ramps
  • Enhanced safety


HiRate™ 650 Series

Brine Tolerant Friction Reducers
For service companies looking for brine tolerant friction reducers, Innospec offers its HiRate™ 650 series. Studies have shown that, over time, cationic friction reducers cause gunk to build up in
producing wells. Only Innospec has been able to solve this problem for our clients by developing and introducing our non-cationic, brine tolerant friction reducers.

HiRate 650 series is selection of high molecular weight friction reducers designed to be added “on-the-fly” to fresh to very heavy brines. The portfolio is comprised of both anionic and cationic polymers. These single component emulsion polymers are designed to perform well in a wide variety of stimulation applications.

HiRate Plus™ Series

Slickwater fracturing systems depend largely on high performance friction reducers (FR) to achieve the pump rates required for proppant transport and suitable fracture geometry. While simple to use onsite, traditional emulsion-based friction reducers have reached their limits in efficiency and affordability.

To overcome these existing FR limits to provide a solution for service companies that would like to offer friction reduction and sand transport at reduced treating pressures—all while maintaining operational simplicity—Innospec Oilfield Services (IOFS) developed its affordable, high-efficiency friction reducer (HEFR) HiRate™ Plus series.

The only proven, patent-pending HEFR, HiRate Plus is an invert polymer emulsion-based FR specifically designed for ultra-fast inversion and hydration, imparting significantly improved friction reduction efficiency. Easy to mix and meter, the HiRate Plus system—unlike conventional emulsion-based FRs—is based on a higher polymer activity that allows less product per stage; thereby saving operators time and money. And for those chasing pump rate, the product has a better pressure to rate ratio than the conventional FRs, which allows higher treating rates.

HiRate™ MAXX High Efficiency Friction Reducers

Today’s high viscosity friction reducers (HEFRs) are intended to reduce friction in the wellbore during the drilling and stimulation processes in unconventional reservoirs such as shales and coal beds. But the large volumes of water pumped, and high pump rates required, often result in damaging high friction pressures caused by turbulent fluid flow.

Another industry-first from Innospec, the HiRate™ MAXX invert polymer emulsion-based high viscosity friction reducer system delivers lower pumping pressures and higher pump rates—with far less product used. Saving customers significant time and money—while enhancing safety—HiRate Maxx is specifically designed for greatly improved friction reduction efficiency with ultra-fast inversion.

  • Invert polymer emulsion-based FR is easy to mix and monitor
  • Using far less product—a gallon or less per thousand— treating rate is nearly 50% faster than conventional friction reducers
  • In a hybrid process, HiRate MAXX enhances fluid viscosity with zero reliance on guar-based fluids

Easy to mix and meter, the HiRate MAXX 1250 system—unlike conventional emulsion-based, high viscosity friction reducers—allows less product per stage; thereby saving operators time and money. Indeed, for those chasing pump rates, this product has a better pressure-to-rate ratio than conventional friction reducers—which allows for far higher treating rates. While the HiRate MAXX 1250 offering is an anionic, high molecular weight polyacrylamide that performs optimally in fresh water when run as designed, it can also be used in some TDS waters to provide cost efficient friction reduction.

HiRate MAXX 3250 is a high brine variant of the product family. The HiRate MAXX family has a lower pressure to ratio than conventional FRs, allowing higher treating rates, with more aggressive sand ramps to save both time and water.
