Paper presented at the SPE Asia Pacific Enhanced Oil Recovery Conference, August 11–13, 2015
Paper Number: SPE-174577-MS
... Abstract While the principles of enhanced oil recovery (EOR) are not new, field implementation has been scarce, particularly in the case of dual-porosity naturally fractured reservoirs, where the interaction of two different porous media creates a more complex displacement process. Several...

... of surfactant and polymer in carbonate porous media were investigated experimentally and analytically in order to study the mechanism and quantify the contribution of each effect. Single phase flow tests of surfactant, polymer and surfactant-polymer mixture were conducted on reservoir carbonate core plugs...

Paper Number: SPE-174689-MS
... Abstract Polymer viscoelastic effects associated with flow through porous media and its influence on residual oil mobilization are still widely debated. A number of measurement techniques have been develop recently to characterize viscoelastic parameters. However, how these results should...

... channels, non-uniform flow channels, and viscoelasticity. To explain the apparent shear-thickening behaviour in porous media, the existing models use an ad hoc hypothesis; that is, the experimental evidence for these effects is missing. The objective of this study is to obtain a mechanistic picture. We...

.... This third phase is known as a microemulsion. While the flow properties of crude oil and polymer-enriched brine are well understood, little has been done to characterize the microemulsion phase, particularly with respect to rheology in porous media. Here, preliminary measurements of microemulsion rheology...
