composition, and method of forming an augmented oil recovery well injection composition.

摘要

augmented petroleum recovery methods are described which use the compositions including an anionic alkyl polyether surfactant having the general structure r1ja, where r1 is a primary or secondary radical group c8-c18, j is an alternative block polyether segment, or random, block, alternate having the structure [(po) x (eo) y (bo) z], where x is from 4 to 18, y is from 0 to 20, and z is from 0 to 5, and a is an anionic group; a co-active having the general structure (r2) q (b) ph-1-ph (d) (r3) r, where r2 and r3 are each independently a primary or secondary alkyl group, linear or branched c8-c24, b and are anionic groups, q is from 1 to 3, r is from 1 to 3, and l is o or ch2; and an alkoxy alcohol.
