Abstract

Disclosed herein are the methods of using specific multiple charged cationic compounds, which are derived from polyamines through an aza-Michael addition with an α,β-unsaturated carbonyl compound, in a clay treatment composition to reduces clay swelling, clay migration, and sludge formation in a subterranean formation in oil and gas operations. The disclosed methods or compositions are found to be more effective than those methods or compositions including commonly used for reducing clay swelling, clay migration, and sludge formation.

First claim

What is claimed is:

1 . A method of stabilizing swellable clays and/or reducing formation of sludge in a subterranean formation comprising:
providing a clay treatment composition into a subterranean formation, wherein the clay treatment composition comprises a compound or its salt derived from an aza-Michael Addition Reaction between a polyamine and an α,β-unsaturated carbonyl compound according to the following formula

and
one or more clay treatment composition agents,
wherein:
X is NH or O;
R 2 is H, CH 3 , or an unsubstituted, linear or branched C 2 -C 10 alkyl, alkenyl, or alkynyl group;
R 3 is absent or an unsubstituted, linear C 1 -C 30 alkylene group;
Y is —NR 4 R 5 R 6 (+) or a salt thereof; and
R 4 , R 5 , and R 6 are independently a C 1 -C 10 alkyl group,
wherein the compound is a multiple charged cationic compound having 2 or more positive charges; and
wherein the clay treatment composition stabilizes swellable clays and reduces formation of sludge, or both.
