Hydrocarbon recovery comprising injecting a slug comprising oil soluble alkoxylated surfactants from lignin Patent #: 5230814
AbstractA process for recovering hydrocarbons from a subterranean hydrocarbon-bearing reservoir comprising:contacting the reservoir with at least one plant derived aromatic containing component having ortho-quinone functionality in an amount effective to promote the chemical modification of at least one component of the hydrocarbons in the reservoir and optimally at least one additional oxidant in an amount effective to do at least one of the following: maintain at least partially the promoting activity of the plant derived aromatic component; produce at least a portion of plant derived aromatic component; and oxidize at least a portion of a component of the hydrocarbons, the contacting occurring at conditions effective to chemically modify the component of the hydrocarbons in the reservoir; andrecovering hydrocarbons from the reservoir.
