ABSTRACT:
An improved oil-base drilling fluid comprising a continuous oil phase and a dispersed internal phase using aqueous non-halide salt solutions is described. Preferably, the non-halide salt is potassium acetate, calcium acetate, sodium proprionate or combinations thereof, however, citrate, tartrate, or gluconate salts may also be used. Emulsifiers, wetting agents, and other chemicals may be added in varying concentrations to achieve desired characteristics for the drilling fluid. The composition has suitable rheological properties, stability, and hole cleaning abilities for use as a drilling fluid; and it is more compatible with environmentally acceptable land disposal methods than conventional oil-base drilling fluids used in land drilling applications.
