ABSTRACT:
Moderate strength cement plugs and viscous pills may be formed by adding slag cement in both conventional particle size and microfine particle sizes to oil-based drilling fluids which contain water as the internal phase of an oil-water emulsion. The water may be present as a calcium chloride brine. Quantities of cementitious mixtures including slag cement, hydrocarbon oil, setting activators, such as sodium hydroxide and sodium carbonate, and nonyl phenol surfactants may be pumped into wellbores using conventional circulation techniques or conventional squeeze cementing techniques to form cement plugs, control lost circulation, or fix certain hydrocarbon oil wastes for disposal in subterranean formations.
