Oil Based Mud Drilling Cuttings Treating Solutions

  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

Water Based Mud Drilling Cuttings Management

In  geotechnical engineering ,   drilling fluid is used to aid the drilling of  boreholes   into the earth , o ften used while drilling  oil  and  natural gas  wells and on exploration drilling rigs , and  also for much simpler boreholes  like   water wells . Liquid drilling fluid is often called drilling mud. The three main categories of drilling fluids are water-based mud (which can be dispersed and non-dispersed), non-aqueous mud, usually called oil-based mud, and gaseous drilling fluid, in which a wide range of  gases  can be used. The main functions of drilling fluids include :  providing  hydrostatic pressure  to prevent  formation fluids  from entering into the well bore, keeping the  drill bit  cool and clean during drilling, carrying out drill cuttings, and suspending the drill cuttings while drilling is paused and when the drilling assembly is brought in and out of the hole. The drilling fluid used for a particular job is selected to avoid formation damage  and to limi
