Abstract
A method for the preparation, drying and use of a stable aluminum citrate solution is disclosed. The method involves first mixing a solution containing an aluminum-chloride compound having a molar ratio of aluminum to chloride greater than about 1:3 with an aqueous solution comprising citrate. This "starter"
solution is agitated at a sufficient rate to keep the slurry moving while the pH of the mixture is adjusted to a level of about 5.0 to about 9Ø The final aluminum citrate product is used to crosslink water-soluble polymer in solution for the purpose of restricting water flow in subterranean formations.
The resultant aluminum citrate solution may be used either as a liquid or dried prior to shipping and using at a remote location.
