Abstract
Embodiments of the present disclosure include compositions for enhanced oil recovery and methods of using the same. Compositions of the present disclosure include particles of a hydrophobic polymer having constitutional repeating units of which at least 10 percent are hydrolysable and through hydrolysis increase a viscosity of the aqueous composition within a subterranean formation.
Claims20
An aqueous composition for enhanced hydrocarbon fluid recovery in a subterranean formation, comprising:
- particles of a hydrophobic polymer having constitutional repeating units of which at least 10 percent are hydrolysable to increase a viscosity of the aqueous composition within the subterranean formation.
The aqueous composition of claim I, where the particles of the hydrophobic polymer having constitutional repeating units of which at least 20 percent are hydrolysable and through hydrolysis increase the viscosity of the aqueous composition within the subterranean formation.
A method for enhanced hydrocarbon fluid recovery, comprising:
- injecting an aqueous composition into a subterranean formation, where the aqueous composition includes particles of a hydrophobic polymer having constitutional repeating units of which at least 10 percent are hydrolysable;
- and
- allowing the at least 10 percent of the constitutional repeating units to hydrolyze within the subterranean formation to increase a viscosity of the aqueous composition.
