Successful Breaker Optimization for Polyacrylamide Friction Reducers Used in Slickwater Fracturing | SPE Hydraulic Fracturing Technology
Most friction reducers used in slickwater fracture stimulation are high-molecular-weight polyacrylamide emulsions. Since these friction reducers are typically pumped at low concentrations (0.5 to 2 gpt), the industry belief has been that these
Traditionally, friction reducer systems have been used to promote laminar flow in pipe to reduce friction pressure in pumping of low viscosity, slickwater-type fracture treatments. In these types of treatments, velocity is the key factor in
Successful Breaker Optimization for Polyacrylamide Friction Reducers Used in Slickwater Fracturing | Request PDF
Friction-reduction performance, proppant settling, breakability, and coreflood experiments were conducted to investigate the new friction reducer (FR1) in terms of friction-reduction, breakability
Anionic polyacrylamide solution viscosity reflects mainly due to internal friction between molecules of the liquid flow generated by the movement or relative. Friction within the structure of the polymer, the nature of the solvent, solution
- What is a high molecular weight polyacrylamide (PAM)?
- ... High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
