  • Gelable liquid and method for selectively inhibiting the gelation of a gelable liquid
    Patent number: 7287588
    Abstract: A method for selectively blocking water inflow from a water-producing formation of a hydrocarbon well provides for injecting into the well a controlled-gelation aqueous solution containing a hydrophobically-aggregating gelling agent and an effective amount of an inhibitor which suppresses hydrophobic aggregation of the gelling agent. The gelling agent is a water soluble-copolymer comprising hydrophilic and hydrophobic monomer units. The inhibitor is soluble in water so that when the controlled-gelation aqueous solution contacts aqueous media the inhibitor disperses so that gelation occurs and the formation is blocked. However, the inhibitor is substantially insoluble in hydrocarbons so that when the controlled-gelation aqueous solution contacts hydrocarbon media the inhibitor continues to suppress said hydrophobic aggregation and gelation is suppressed. The solution may be used to control the flow of water into oil wells, making it possible to reduce the water cut.
