Contaminant hydrogeological processes occurring in porous media are typically not
amenable to direct observation. As a result, indirect measurements (eg, contaminant …

Polymer gel systems have been widely applied to control excessive water and improve oil
recovery (IOR) in petroleum reservoirs. They are usually divided into two main types, in-situ …

Improved network flow models require the incorporation of increasingly accurate
geometrical characterization of the microscale pore structure as well as greater information …

Synchrotron-based X-ray microtomography (micro CT) at the Advanced Light Source (ALS)
line 8.3. 2 at the Lawrence Berkeley National Laboratory produces three-dimensional …

Dissolution and precipitation reactions are the primary mechanisms that occur when a rock
(ie, a mineral assemblage) is in contact with a fluid out of equilibrium. They play a critical …

Using oil–wet polyethylene core models, we present the development of robust throat
finding techniques for the extraction, from X-ray microtomographic images, of a pore network …

This paper provides guidance on when and where relativepermeability-modification/
disproportionate-permeability-reduction (RPM/DPR) water-shutoff (WSO) treatments can be …

We present the results of a pore-scale experimental study of residual trapping in
consolidated sandstone and carbonate rock samples under confining stress. We investigate …

A laboratory study characterized partially formed chromium (III)-carboxylate/acrylamide-
polymer (CC/AP) gels for water shutoff in fractures. These partially formed gels showed …

This paper investigates washout of mature Cr (III)-acetate-HPAM gels from fractures. After
gel placement, the pressure gradient for gel washout during brine or oil flow was similar to …
