Abstract: Methods include drilling at least one interval of a wellbore with a water-based wellbore fluid producing a filtercake in the at least one interval of the wellbore. The methods also include gravel packing an interval of a wellbore traversing a subterranean formation with a gravel pack that comprises polyhydroxycarboxylic acid, and hydrolyzing the polyhydroxycarboxylic acid to degrade at least a portion of the filtercake.

Abstract: Methods of delivering a low density solvent into a wellbore include combining an oleaginous solvent and a nonoleaginous fluid to form an emulsion, and injecting the emulsion into a wellbore. Other uses of low density solvent systems may include dissolving waxes and wax-containing residues in a wellbore, on downhole tools, from sand screens, or use in general cleanup operations in and outside of the wellbore.

Abstract: A method for completing a wellbore may include introducing an oil-containing wellbore fluid into a wellbore having water-based filtercake on walls thereof, contacting the oil-containing wellbore fluid with an oil-swellable element in the wellbore; and allowing swelling of the oil-swellable element, where the oil-containing wellbore fluid is substantially free of unassociated surfactants, emulsifiers, or dispersants and may include an oleaginous fluid and a weighting agent.
