NRG-EMUL-O is a high-performance and high-performance oil-soluble agent used as an emulsifier in invert emulsion drilling fluids. NRG-EMUL-O improves the stability of the rheological properties of the oil-based drilling sysytem under prolonged exposure to temperatures up to 320°F , as well as electrical stability up to 2000V, depending on the type of substrate and the formulation of the drilling mud.
