A method is described of emplacing an aqueous cement slurry into a well bore which contains an oil base composition having dispersed therein oil wet particles. The method consists of: introducing into the well bore and into contact with the oil based composition, a spacer composition comprising: an aqueous fluid; a nonylphenol admixture comprising from about 20 to about 80 percent by volume nonylphenols ethoxylated with from about 1 to about 6 moles of ethylene oxide and from about 20 to about 80 percent by volume nonylphenols ethoxylated with from about 7 to about 14 moles of ethylene oxide, present in amount of from about 1 to about 10 percent by volume of the composition; and, at least one member selected from the group consisting of: a sulfonated linear C/sub 8/ to C/sub 18/ straight chain alcohol ethoxylated with from 2 to 20 moles of ethylene oxide; an aliphatic glycol ether containing from about 3 to about 12 carbon atoms, and an alcohol containing from about 3 to about 8 carbon atoms ethoxylated with from about 2 to about 4 moles of ethylene oxide, the alcohol being different from the aliphatic glycol when present, the selected member being individually present in an amount of from about 0 to about 5 percent by volume of the composition; displacing at least a portion of the oil based composition from an area in the well bore into which the cement slurry is to be emplaced with the spacer composition; displacing at least a portion of the spacer composition from the area in the well bore into which an aqueous cement slurry is to be emplaced with the cement slurry; and permitting the cement slurry to be set up in the area.
