Frac Friction Reducer (Low Cost Polyacrylamide & Derivatives)
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).
In a preferred embodiment, the composition contains up to 55% polyacrylamide, up to 70% petroleum distillate, up to 5% surfactant, and up to 5% dispersant. The water-soluble polymer of the present composition is preferably polyacrylamide. Polyacrylamide in its dry form resembles granular particles. Alternatively, polyacrylamide can be hydrolyzed or emulsified via a synthesized process involving controlled-environment aqueous chemical reactions. The present composition, however, provides a new alternative delivery for polyacrylamide: a non-aqueous polyacrylamide slurry, using an oil-based suspension.
Polyacrylamide is a hydrophilic, water-soluble polymer that can comprise nonionic, cationic, anionic, or zwitterionic charge. Hydrated polyacrylamide of powder origins can reduce friction and turbulence in a system allowing faster pump rates and reducing pumping pressures all while carrying sufficient proppant for typical oil and gas well applications. Dry powder polyacrylamide can be hard to utilize as it absorbs ambient moisture and is prone to aggregation and clump formation. Decreasing the particle size of the powder enhances the hydration and inversion rate of the polyacrylamide, but exacerbates the powder's absorption of moisture.
