Drilling cuttings treating solutions will depend on the drilling mud characteristics. Oil-based mud is a mud where the base fluid is a petroleum product such as diesel fuel , kerosene, fuel oil, selected crude oil or mineral oil. For OBM ’ s complexity, the drilling cuttings treating solutions will have more strict demands on the processing equipment. Oil-based mud are used for many reasons, including increased lubricity, enhanced shale inhibition, and greater cleaning abilities with less viscosity. Oil-based mud also withstand greater heat without breaking down. The use of oil-based mud has special considerations, including cost, environmental considerations such as disposal of cuttings in an appropriate place, and the exploratory disadvantages of using oil-based mud, especially in wildcat wells. Using an oil-based mud interferes with the geochemical analysis of cuttings and cores and with the determination of API gravity because the base fluid cannot be distin
