摘要： A process for recovering monomers and solvent present in a waste stream including the steps of: (a) providing a waste feed stream containing monomers, solvent and impurities; (b) subjecting the waste feed stream of step (a) to a separation process under conditions for separating the monomers and solvent from the impurities of the waste stream; (c) recovering the monomers and solvent in one or more streams; and (d) passing the one or more of the monomer and solvent streams from step (c) to further processing.

摘要： The present invention relates to an in situ staged steam extraction method for removing petroleum products from a heavy oil or bitumen reservoir from subterranean locations. Specifically, each injection stage comprises a different steam composition. A steam composition may consist essentially of steam or may comprise one or more enhanced oil recovery agent.

摘要： The present invention relates to a method to stimulate additional oil recovery from a post-CHOPS well in an oil-bearing formation. Specifically, the present invention involves the step of treating a post-CHOPS well in an oil-bearing formation with a composition comprising an aqueous solution of a polyoxylated alcohol.
