Abstract
A method of inhibiting an undesirable fluid flow path, including pumping a flow of fluid downhole, the flow of fluid containing a plurality of shape-change particles; depositing the shape-change particles in an undesirable fluid flow path in a downhole structure; transitioning the shape-change particles from a first shape to a second shape; forming a plug with the shape-change particles when in the second shape; and inhibiting the undesirable fluid flow path from fluid flow therethrough with the plug of shape-change particles.
