Partially hydrolyzed polyacrylamide (HPAM) is by far the most used synthetic polymer in enhanced oil recovery (EOR) projects. Shortcomings of HPAM include a highly molecular weight (Mw) dependent viscosity yield and decreasing viscosifying ability wi

Polymers are attractive enhanced oil recovery (EOR) chemicals that improve sweep and accelerate production. There is an ongoing search for polymers that are more temperature-, salinity-, and shear-stable as fields in increasingly challenging environm

Transport in Porous Media
We study a heuristic, core-scale model for the transport of polymer particles in a two phase (oil and water) porous medium. We are motivated by recent experimental observations which report increased oil recovery when polymers are injected after the

We study the transport of inertial particles in water flow in porous media. Our interest lies in understanding the accumulation of particles including the possibility of clogging. We propose that accumulation can be a result of hydrodynamic effects:

The majority of the polymers used in enhanced oil recovery (EOR) processes are water-soluble, acrylamide-based polymers, typically partially hydrolyzed polyacrylamide (HPAM). Industrial-scale production of HPAM polymers for EOR involves either posthy

It is well-established that injecting water with significantly lower salinity than the formation water salinity may give increased oil recovery. Although less well studied, the observed low-salinity effect has drawn attention to possible benefits fro

Ideally, in a chemical flooding process, one would like to inject a surfactant solution that has good solubility at the relevant conditions, ultralow interfacial tension (efficient oil mobilisation) and low loss of surfactant (better economics) in th

A laboratory selection of salinity for a low salinity water-low salinity surfactant (LS-LSS) process is presented in this paper with systematical investigation on surfactant phase behavior, interfacial tension (IFT), and dynamic retention in porous m
