ABSTRACT:
Hydrocarbon bearing earth formations are treated to reduce formation permeability and fill void spaces by injecting a polymer gel solution having an artificial matrix material dispersed therein and comprising beads of materials such as polystyrene and polycarbonate having densities substantially the same as the density of the polymer gel to improve distribution of the artificial matrix material into such void spaces.
