Treatment fluids for reducing subterranean formation damage

摘要

Methods including providing a treatment fluid comprising a base fluid, a wettability altering surfactant, and a chelating agent, wherein the treatment fluid has a pH of at least about 5; introducing the treatment fluid into a subterranean formation; altering a wettability of the subterranean formation from oil-wet to either mixed-wet or water-wet with the wettability altering surfactant; and complexing metal ions in the subterranean formation with the chelating agent.
