Abstract

Embodiments relate to removing residue from a well bore and well bore equipment with a treatment fluid composition, and in some embodiments, to treatment fluid compositions that comprise nanoparticles. An embodiment provides a method of removing drilling fluid residue from the surfaces of well equipment. The method comprising: applying a solid nanoparticle film to at least a portion of the surfaces of the well equipment with a treatment fluid comprising solid nanoparticles; and allowing the solid nanoparticles to interact with the surfaces of the well equipment and the drilling fluid residue adhered to the surfaces of the well equipment to remove at least a portion of the drilling fluid residue from the surfaces of the well equipment.
