Non-Aqueous Fluids

PDT’s range of non-aqueous fluids range from industry-standard diesel- or mineral oil-based fluids to highly specialized synthetic-based systems. In non-aqueous drilling fluids, the water phase is emulsified in a continuous oil phase in what is termed a water-in-oil emulsion, or invert emulsion. Invert emulsion drilling fluids are often easily adaptable to various pressures, temperatures, and wellbore conditions. These fluids are stable in the presence of high-electrolyte concentrations, soluble gases, and high temperatures.
