Abstract

Emulsion muds are water based drilling fluids, which contain dispersed oil or synthetic hydrocarbon as an internal phase. Drilling muds are very multifaceted liquids mostly made of up clay suspensions and other materials used as circulatory fluids during well drilling. The ability of drilling fluids, in particular invert emulsion muds to perform their functions, such as removal and transportation of cuttings from the well, lubrication and cooling of drill bits and parts, well wall support and formation fluid containment is all dependent on the rheological properties such as their elasticity, plasticity, viscosity and how they flow and distort. The objective of this paper is to carry out an experimental study on oil based drilling fluid; invert emulsion mud, study its rheological properties, its formulation and how they affect well construction and stability. The mud mixture would also be simulated using Drill Bench.
