Abstract
A method of treating a subterranean formation to protect against solid deposition and corrosion attack includes flowing a pre-flush fluid to a specified downhole location within the subterranean formation. A main treatment fluid is flowed to the specified downhole location. The main treatment fluid includes a scale inhibitor configured to inhibit formation of scale within the subterranean formation. At a subsurface level, an overflush foam is generated. The overflush foam includes an aqueous fluid and a gas. The overflush foam is shear thinning and non-Newtonian. The overflush foam is flowed to the specified downhole location.
