Summary: | The present disclosure relates to spacer fluids (240) for use in subterranean operations and, more particularly, in certain embodiments, to spacer fluids (240) that include a spacer additive comprising a solid scouring material and a biopolymer gum while being essential free of clay. An example method may comprise spacer fluid (240) comprise water and a spacer additive. The spacer additive may comprise a solid scouring material and a biopolymer gum, wherein the solid scouring material comprises crystalline silica in an amount of about 5 wt. % or less, and wherein the spacer fluid (240) is essentially free of clay. The example method may further comprise and introducing the spacer fluid (240) into a wellbore (120) to displace at least a portion of a first fluid in the wellbore (120). |
