Abstract: A method of grafting galactomannan-type polysaccharide polymers, preferably guar, to a functional group by irradiation with high energy electron beams in the presence of an unsaturated monomer-compressing the described functional group. The method may include the depolymerization of the grafted polymer to a pre-selected low molecular weight. The preferred galactomannans for treatment according to this method are guar gum, guar splits and hydroxypropyl guar. In a preferred embodiment the guar gum is also depolymerized, preferably to a molecular weight of below about 700,000 Daltons, and most preferably to a molecular weight of between about 100,000 Daltons to about 250,000 Daltons. The depolymerized guar most preferably has a polydispersity of less than about 3.0 and is useful in oil well fracturing to enhance oil production.

Abstract: A method for enhancing recovery of oil from an oil-bearing carbonate formation within a reservoir. The method has the steps of (a) introducing a viscous gel under pressure into the oil-bearing carbonate formation and (b) extracting oil. The aqueous viscous gel has water and an amount of a non-polymeric viscosifying surfactant sufficient to provide the flooding fluid with an oil/water interfacial surface tension of about 10 mN/m or less and a viscosity of about 10 cP or more of the one or more non-polymeric surfactants. The one or more non-polymeric, viscosifying surfactants is selected from the group of one or more cationic surfactants, one or more zwitterionic surfactants, one or more anionic surfactants, one or more amphoteric surfactants, and combinations thereof. In a preferred embodiment, the aqueous viscous gel is also substantially free of solids.
