  • Method for controlling oil reservoir permeability using biomass oil
    Patent number: 5115084
    Abstract: A method for controlling the permeability of a petroleum-bearing subterranean formation including the steps of producing from biomass, a water-insoluble viscous biomass oil, and injecting the biomass oil into the petroleum bearing formation to decrease the permeability of at least some of the formation for altering flow paths through the formation to increase petroleum yield.
