摘要： Accordingly, this disclosure describes systems, compositions, and methods that may use pelletized diverting agent particulates for diversion, fluid loss control, and/or other subterranean treatments for controlling fluid flow in subterranean formations. In an embodiment, a method comprising: introducing a treatment fluid into a wellbore penetrating a subterranean formation wherein the treatment fluid comprises: a base fluid; a pelletized diverting agent comprising a degradable polymer, wherein the pelletized diverting agent at least partially plugs a zone in the subterranean formation; and diverting at least a portion of the treatment fluid and/or a subsequently introduced fluid away from the zone. In an embodiment, a treatment fluid comprising: a base fluid; and a pelletized diverting agent comprising a degradable polymer.

摘要： Methods, compositions, and systems that use hydrogels of graft polymers for diversion of acidic treatment fluids in subterranean formations. A method for acid diversion may comprise: applying a first acidizing treatment to a first treatment zone of a subterranean formation; introducing a hydrogel to the first treatment zone, wherein the hydrogel comprises a graft polymer that is crosslinked; and applying a second acidizing treatment to the subterranean formation, wherein the hydrogel diverts the second acidizing treatment to a second treatment zone.
