ABSTRACT:
Liquid fluid loss control additives for oil field cements are provided which have long storage lives without excessive settling and which can be mixed with cement slurries without the formation of gel balls or fish eyes. The liquid additives consist essentially of a liquid hydrocarbon, a hydrophilic water soluble polymer, an organophilic clay suspending agent, an organic sulfonate dispersant, a polyamide amine surfactant for oil wetting the polymer and a surfactant for stripping liquid hydrocarbon from the polymer when contacted with water.
