Abstract
Methods for drilling well bores and cementing a pipe string in the well bores using oil-based settable drilling fluids are provided. The oil-based settable drilling fluid compositions basically comprise an oil external emulsion comprising oil, water and an emulsifying surfactant; a hydraulically settable component; and a de-emulsifying surfactant for de-emulsifying the oil-external emulsion when the emulsion is cured.
