Why use oil based muds? Advantages: • Good rheological properties at temperatures as high as 500 oF. (especially deeper well).

Oil-based muds. Oil-based muds were developed to prevent water from entering the pore spaces and causing formation damage. There are several advantages and disadvantages of this type of mud system. The advantages include the following: 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. Advantages and Disadvantages of Water-based and Oil-based Mud 1. Water-based mud can swell shale formation, a brittle mineral, 2. Gases produced among shale cracks whose non-organic part is possbly aqueous wetting phase can be 3. Water-based mud can easily block the layers of very low

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.

Oil based mud Advantages: Clays do not hydrate and swell / excellent wellborn stability; Low formation damage / production is improved; Mud properties are more stable;Contamination resistance is increased;Good lubrication / Reduced risk of differential sticking Advantages and disadvantages of oil based drilling fluid: 1. Compared with water-based drilling fluid, oil based drilling fluid has the advantages of high temperature resistance, anti salt calcium influx, be conducive to wellbore stability, good lubrication and less damage to the oil and gas reservoirs. The advantages are: high drilling rates; lowered drill pipe torque and drag, less bit balling and; reduction in differential sticking. Oil-based muds are expensive, but are worth the cost when drilling through: troublesome shales that would otherwise swell and disperse in water based mud e.g. smectite, The two most common types are oil-based muds and water-based muds, with both having many variations designed to meet the demands of specific drilling applications. When determining what type of mud is most appropriate for a drilling project, mud formulators take into account multiple factors such as geology, geo-pressure, and the casing point

First of all, both water-based and oil-base drilling fluids have advantages and disadvantages, and they adapt to different stratigraphic conditions. Therefore, there is no superior or inferior stratum, and it is impossible to arbitrarily say which one is the future development trend. API and IADC mud is oil based drilling mud which has oil as the external phase. mud is oil based invert emulsion because the external phase is oil and the internal phase is water. Water oil ratio range of 50% oil: water 50% oil 95% to 5% water. Currently, many operators prefer to use oil-based mud instead of water based mud .

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 muds.
