Abstract

Fluid loss materials including carboxymethylcellulose and zirconium-based crosslinkers may be employed as fluid loss materials in methods of treating subterranean formations. One method includes providing a treatment fluid including carboxymethylcellulose (CMC) and a crosslinker including zirconium, wherein the carboxymethylcellulose has a degree of substitution in a range of from about 0.5 to about 2.5, wherein the crosslinker including zirconium includes one selected from the group consisting of ammonium zirconium fluoride, zirconium 2-ethylhexanoate, zirconium acetate, zirconium neodecanoate, zirconium acetylacetonate, tetrakis(triethanolamine) zirconate, zirconium carbonate, ammonium zirconium carbonate, zirconyl ammonium carbonate, zirconium complex of hydroxyethyl glycine, zirconium malonate, zirconium propionate, zirconium lactate, zirconium acetate lactate, and zirconium tartrate, and placing the treatment fluid in a subterranean formation, wherein the treatment fluid controls fluid loss in a permeable portion of the subterranean formation penetrated by a wellbore.
