... a better conductivity after fracturing treatment. A sufficiently high injection rate of the slurry is also needed to enable effective proppant flow in rough fractures. At certain low injection rate, the proppants carried by a low polymer solution might not exhibit a tree-like settling pattern, diminishing...

... that represent quarter of five-spot pattern with one injector and one producer was utilized to run different scenarios using 1,000 ppm partially hydrolyzed polyacrylamide (HPAM) polymer solution with brine varying in salinities from 2,000 to ppm using UTGEL simulator. The in-situ gelation system consisted...

..., measurement of bulk extensional properties for relatively low viscous enhanced oil recovery polymer solutions remains a challenge. In this study, extensional rheology measurements are performed using capillary breakup extensional rheometer (CaBER). The CaBER setup uses a stepstrain to stretch a droplet...

... Abstract It has been long believed that the viscoelasticity of polymer solution improves the displacement efficiency in polymer flood operations, but the individual effect of elasticity has not been distilled for a single viscoelastic polymer. In this study, the effect of elasticity of polymer...

... performance tests can be used to differentiate between intra-molecular and inter-molecular cross-linked reactions. Viscosity increases with time if inter-molecular cross-linked reaction occurs in a polymer solution, but stays constant or slightly decreases with time if intra-molecular cross-linked reaction...

... Abstract To increase capillary imbibition recovery rate and deplete matrix oil efficiently, surfactant and polymer solutions can be injected into naturally fractured reservoirs. Laboratory experiments are needed to understand the response of the reservoir rock and fluids to these applications...
