Abstract
Official abstract text for this publication.
Chemical compounds that are N-acyl amino acids or derivatives thereof having long chain N-acyl groups were found to have oil-releasing activity. Solutions containing these compounds may be introduced into oil reservoirs or onto oil-contaminated surface sites to release oil from oil-coated surfaces. The released oil may be recovered for further processing or waste disposal.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for improving oil recovery from an oil-coated surface comprising: a) providing an aqueous composition comprising at least one compound of the structure: where: R 1 is H, CH 3 , or is part of a heterocyclic ring (—CH 2 —) n , where n=3, 4, or 5 and the ring is directly connected to the rest of the structure at R 4 ; R 2 is…
