Abstract
Viscous degradable fluids for use in fluid loss control, diversion, gravel packing, fracturing, and acidizing operations, method of preparing the viscous degradable fluids, and methods of using the viscous degradable fluids in subterranean operations. At least one aliphatic polyester is dissolved in a solvent comprising triacetin to form a viscous degradable fluid. The viscous degradable fluid can be injected directly into a subterranean formation or mixed with other fluids and/or additives before being injected into the subterranean formation, where it can temporarily block or restrict flow through openings in the formation.
