Abstract
Methods of treating a subterranean formation are disclosed that include introducing a treatment fluid including thermally shrinkable fibers and a particulate material into a subterranean formation via a wellbore, adjusting at least one parameter of the treatment fluid to trigger the association of the thermally shrinkable fibers, and forming a porous pack including a network of shrunken fibers by applying heat sufficient to raise the temperature of the thermally shrinkable fibers to a temperature at or above a shrinking initiation temperature of the thermally shrinkable fibers.

A method for treating a subterranean formation comprising:
- introducing a treatment fluid including thermally shrinkable fibers and a particulate material into a subterranean formation via a wellbore;
- thermally triggering a mechanical association of the thermally shrinkable fibers;
- and
- after triggering the mechanical association of the thermally shrinkable fibers, forming a porous pack comprising a network of shrunken fibers by conducting a shrinking process including applying heat sufficient to raise the temperature of the thermally shrinkable fibers to a temperature at or above a shrinking initiation temperature of the thermally shrinkable fibers;
- wherein at least a portion of the shrunken fibers are made to assume a geometry in which the shrunken fiber is hooked on one or both ends as a result of the shrinking process.
