Abstract

See full text

A method of treating a well including the steps of: (A) treating a first aqueous fluid comprising seawater with electrocoagulation to obtain a second aqueous fluid, wherein the second aqueous fluid has a reduced concentration of magnesium ions relative to the original concentration of magnesium ions in the first aqueous fluid; (B) forming a treatment fluid comprising: (i) an aqueous phase, wherein the aqueous phase comprises the second aqueous fluid, and (ii) a viscosity-increasing agent in the aqueous phase; and (C) introducing the treatment fluid into a well. The aqueous phase can have a pH of at least about 9 or the treatment fluid can be introduced into a well at a design temperature of at least about 93° C. (200° F.).
