Much earlier, oil had been used to loosen stuck drill pipe and to "slick up the hole" before running casing25. Drillers in the Oklahoma City field (1934 -1936) added crude oil to mud to reduce sticking of pipe, and in 1937 a drilling contractor in Pottawatamie County, Oklahoma, noted a faster drilling rate after adding oil.66 Oil Emulsion Mud, also known as water-based mud or oil in water emulsion is an oilfield emulsion which is used as a drilling fluid while performing drilling operations. In this type of oilfield emulsion, water is present as a continuous phase (or in large amount) and oil is present in the dispersed phase in low amounts of approximately 2% to 5%.

The invention further relates to a use of said composition or of a C1-C10 alcohol and/or an alkoxylated C1-C10 alcohol as demulsifier preferably as demulsifier in an oil based drilling fluid. WO2016141968A1 - Emulsion-breaker for oil based mud invert emulsions - Google Patents Emulsifiers are special products added to the oil mud to be dispersible in the external oil phase, and to ensure emulsion stability of water internal phase under the extreme downhole conditions. Emulsion is dispersion of liquid droplets into another liquid. These liquid droplets are referred to as internal phase. Some of these emulsifiers provide emulsion stability when utilizing nonstandard internal phase fluids. The various wetting agents can enhance emulsion stability while ensuring thorough oil wetting of solids to control rheological properties and fluid loss control. The water phase of oil-based mud can be freshwater, or a solution of sodium or calcium chloride. The external phase is oil and does not allow the water to contact the formation. The shales don't become water wet. Poor stability of the emulsion results in the two layers separating into two distinct layers. The advantages are: high drilling rates; lowered drill pipe torque and drag, less bit balling and

So, emulsion mud can be defined as that category of water based drilling fluids to which oil is added. The oil becomes the dispersed phase and water becomes the continuous phase and invert emulsion mud can be defined as oil based drilling fluids to which water is added.

However, waterbased drilling muds (WBMs) may contain oil and oil-based drilling 5% of water is present, the mud is often referred to as an invert emulsion. 9 Aug 2017 They are Oil-in-Water (O/W) emulsions where the main base fluid may be fresh water, seawater, or brine. These systems incorporate natural clays

A water-base drilling fluid that contains dispersed oil or synthetic hydrocarbon as an internal phase. Early emulsion muds used diesel or crude oil dispersed into alkaline water-base muds. Synthetic liquids are now being substituted for oils in emulsion muds.
