Abstract: The invention is directed to long lasting crosslinked water-soluble swellable polymers, methods for making same, and their uses. More particularly, the invention relates to a composition comprising expandable polymeric particles having cationic sites as well as labile crosslinkers and stable crosslinkers, said particle mixed with a fluid. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric particles are injected into a target zones in the reservoirs and when the heat and/or pH of the reservoir cause degradation of the labile crosslinker and when the particle expands, the cationic sites in the polymer adsorb to the rock in the formation, thus diverting water to lower permeability regions and improving oil recovery. However, many other uses are possible.

Abstract: A colloid gel can include a plurality of positive charged particles mixed and associated with a plurality of negative charged particles so as to form a three-dimensional matrix having a plurality of pores defined by and disposed between the particles. The three-dimensional matrix can have shear thinning under shear and structure stability in the absence of shear. A method of manufacturing the colloid gel can include combining the positive charged particles with the negative charged particles, in a mold or in situ, so as to form the three-dimensional matrix having the plurality of pores.

Abstract: The invention is directed to crosslinked water-soluble swellable polymers, methods for making same and their various uses. More particularly, the invention relates to a composition comprising expandable polymeric particles being made with 0.1-5% hydrophobic monomers and labile crosslinkers and stable crosslinkers, said particles mixed with a fluid. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric particles are injected into a well and when the heat and/or pH of the target zones in the formation cause degradation of the labile crosslinker and when the particle expands, the hydrophobic groups associate to form a hydrophobically associative polymer, thus diverting water to lower permeability regions and improving oil recovery.
