  • Enhanced oil recovery techniques using liposomes
    Patent number: 7798219
    Abstract: Process and a method for enhancing recovery of petroleum from an underground source including injecting into the source, a petroleum displacement agent including fluids and modified liposomes. The liposomes and fluids merge the discrete oil droplets after waterflood into a continuous layer of oil (oil phase) eliminating b-pass of water through oil and employ mobility control through transition of gel phase to liquid crystalline phase.
