Salt-Tolerant Non-Crosslinked Polymer Networks for High-Temperature Weighted Fracturing Fluids in Deep Hydrocarbon Reservoirs
High-density potassium formate fracturing fluids require polymers that hydrate in concentrated brine while providing low friction and proppant suspension at high temperature. We hypothesized that the 2-acrylamido-2-methylpropanesulfonic acid (AMPS) content balances salt-tolerant hydration against molar-mass-dependent c...
