Abstract
The current application discloses compositions and methods for treating a subterranean formation. CO2 swellable elastomers can be used in a treatment fluid to at least partially block a high permeability region, therefore improving the performance of an operation such as matrix stimulation, acidizing, and acid fracturing.
