Plugging and improving oil recovery performance of polyacrylamide nanogel in porous media

Ding H., Geng J., Imqam A., Bai B., Missouri University of Science and Technology, US

The heterogeneity of reservoir is always responsible for problems such as low oil recovery and excessive water production because of the trend of injection fluids to go through higher permeability zone. Hydrogel has been used [...]

Conformance Control through In-situ Gelation of Silica Nanoparticles

Rankin K.M., Nguyen Q.P., The University of Texas at Austin, US

Due to reservoir heterogeneities, oil recovery from fluid injection during secondary and/or tertiary recovery does not occur in an ideal piston-like displacement. Rather sweep efficiency can be much lower than 100% due to heterogeneities such [...]
