Abstract: In a method of gravel packing a wellbore in a subterranean formation, the wellbore comprising a cased section and an uncased section, the method may include pumping into the wellbore a gravel pack composition comprising gravel and a carrier fluid comprising an invert emulsion fluid, where the invert emulsion fluid may comprise: an oleaginous external phase; a non-oleaginous internal phase, wherein a ratio of the oleaginous external phase and non-oleaginous internal phase is less than 50:50 and an emulsifier stabilizing the oleaginous external phase and the non-oleaginous internal phase.

Abstract: A wellbore fluid for dissolving a filtercake includes a chelating agent and an aqueous solution of carboxylate salt. The concentration of the chelating agent is up to 50 percent volume per volume (v/v) in the aqueous solution of carboxylate salt. A method of treating a well includes preparing a wellbore fluid up to 50 percent volume per volume (v/v) chelating agent in an aqueous solution of carboxylate salt. The method further includes emplacing the wellbore fluid downhole such that the wellbore fluid dissolves a filtercake in the well.
