Oil based drilling fluid composition

Oil-based mud is a drilling fluid used in drilling engineering. It is composed of oil as the continuous phase and water as the dispersed phase in conjunction with emulsifiers, wetting agents and gellants. The oil base can be diesel, kerosene, fuel oil, selected crude oil or mineral oil.

Drilling fluids are classified according to their base: Water Base Muds. Solid particles are suspended in water or brine. Oil may be emulsified in the water, in which case water is termed the continuous phase. Oil Base Muds. Solid particles are suspended in oil. Water or brine is emulsi fied in the oil, i.e., oil is the continuous phase. Oil-based drilling fluids use oil as the continuous phase. Lower well friction is one of the advantages with oilbased drilling fluids. They are therefore often used in long-reach wells where friction is a critical parameter. Usually the borehole does not show time-dependent deterioration as with water-based fluids. Oil-based mud is a drilling fluid used in drilling engineering. It is composed of oil as the continuous phase and water as the dispersed phase in conjunction with emulsifiers, wetting agents and gellants. The oil base can be diesel, kerosene, fueloil, selected crude oil or mineral oil. Oil Based Mud is an oilfield emulsion which is used as a drilling fluid while performing drilling operations. In this type of oilfield emulsion, oil is present as a continuous phase (or in large amount) and water is present in the dispersed phase in low amounts of approximately 2% to 5%. It is also referred to as drilling mud or drilling fluid. Synthetic-based drilling fluids have several technological and environmental advantages over water-based and oil-based drilling fluids and can cut total well costs in many cases. Spent drilling fluids and drilling cuttings are among the most significant waste streams from exploration and development activities.

Oil-based drilling fluids originated with the use of crude oil in well completion, but the date of first usage is unknown. Oil was used to drill the productive zone in shallow, low-pressure wells in many early fields. However, drilling fluids that are formulated with diesel- or synthetic-based oil and no water phase are used to drill long shale intervals where the salinity of the formation water is highly variable. By eliminating the water phase, the all-oil drilling fluid can preserve shale stability throughout the interval. Pneumatic-drilling fluids In recent years, the oil-based drilling fluid has gained popularity, but the present environmental movement brings water-based drilling fluids back. They both have their advantages and disadvantages as briefly discussed here. Water-based drilling fluids use water as the continuous phase. Oil-based fluids are well suited for the following applications: Drilling troublesome shales that swell (hydrate) and disperse (slough); Drilling deep, high-temperature holes in which water-base muds solidify; Drilling water-soluble formations such as salt, anhydride, camallite, and potash zones;
