Emulsion based drilling fluids have emerged as an important class of drilling fluid systems, which
have gained a significant interest in modern drilling operations. Oil- in-water (O/W) emulsion mud is
widely used for low pressure and depleted oil and gas reservoirs. On the other side water-in-oil (W/O) invertemulsion mud can be useful in the drilling, completion and work over of subterranean and gauge wells. The stabilization of the emulsion systems is achieved with the help of suitable surfactants. The polymers and bridging agents are used to control the rheological and filtration prop
erties of the drilling fluid systems. This research paper reviews the emerging developments in emulsion based drilling fluids and their effectiveness for oil and gas well drilling.It also discusses the environmental and waste disposal considerations of these drilling fluids at thedrill site.
