Abstract
Herein provided are methods for producing degradable particulates at a drill site, and methods related to the use of such degradable particulates in subterranean applications. In one embodiment, the present invention provides a method comprising: providing a degradable polymer solvent mixture that comprises a degradable polymer and a first solvent; and mixing the degradable polymer solvent mixture with a second solvent at a drill site with shear to form a solid liquid dispersion comprising a solid phase and a liquid phase, the solid phase comprising degradable particulates and the liquid phase comprising the first solvent and the second solvent.
