Abstract
Fracturing operations can be problematic in completed wellbores containing at least one existing fracture, since it can be difficult to seal an existing fracture and initiate a new fracture within a reasonable timeframe due to the presence of particulate materials in the wellbore. Methods for fracturing a completed wellbore can comprise introducing a treatment fluid comprising a plurality of degradable sealing particulates into a completed wellbore penetrating a subterranean formation having an existing fracture therein; sealing the existing fracture with at least a portion of the degradable sealing particulates, thereby forming a degradable particulate seal; after sealing, allowing any degradable sealing particulates remaining in the treatment fluid to degrade, such that the treatment fluid becomes substantially particulate free; and after the treatment fluid becomes substantially particulate free, fracturing the subterranean formation so as to introduce at least one new fracture therein.
