Definition - What does Drilling Mud mean?
Drilling mud is basically a liquid drilling fluid that is used to facilitate the easy drilling of wellbores in the earth. It is often used to drill oil or gas wells and even for exploration drillings of wellbores. Drilling mud is usually of three types, i.e., water-based mud, oil-based mud and gaseous drilling mud. This mud is ideally used with force to create hydrostatic pressure during drilling procedure. Out of the three drilling muds, an oil well can use a particular kind of mud to carry out the drilling operation as per the requirement of the well.
Petropedia explains Drilling Mud
A drilling mud is also known as a drilling fluid system or mud system. This mud is an important component that is used to create force in an oil well during oil construction operation.Because drilling mud stays in contact with the wellbore the entire time of drilling, the operation cannot be completed without it.There are three categories of drilling mud, i.e., oil-based, water-based and gas based.The mud or drilling fluid is usually a thick mixture of fluids, such as seawater, fresh water, brines (natural or synthetic) or oil-based fluids such as diesel oil or mineral oil. Additional components such as thickeners are also added to the fluids to get a certain level of viscosity.
