Patent number: 10876045Abstract: Degradable particulates may allow for temporary redirection or occlusion of a fluid within a subterranean formation. However, many types of degradable particulates can be problematic for large-scale use, such as during subterranean treatment operations. Methods for treating a subterranean formation using degradable particulates may comprise: providing pre-coated particulates comprising a latently dissolvable core and a transient coating surrounding the latently dissolvable core, the latently dissolvable core and the transient coating comprising different materials; and introducing a treatment fluid comprising a carrier fluid and a plurality of the pre-coated particulates into a wellbore penetrating a subterranean formation in conjunction with a stimulation operation, a material comprising the latently dissolvable core being soluble in the carrier fluid or a formation fluid present within the subterranean formation.Type: GrantFiled: November 16, 2015Date of Patent: December 29, 2020Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Jeremy A. Holtsclaw, Larry Steven Eoff, Nathan Carl Schultheiss
