Definition - What does Drilling Fluid mean?
Drilling Fluid is a liquid that is used to facilitate the easy drilling of wellbores in the earth's surface. It is often used to drill oil or gas wells and even exploration drillings of wellbores. Drilling fluid is usually of three types, i.e., water-based mud, oil-based mud and gaseous drilling mud. This fluid is ideally used with force to create hydrostatic pressure during drilling procedure. Out of the three drilling fluids, 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 Fluid
Drilling Fluid is also known as drilling mud. This mud or drilling fluid is an important component that is used to create force in an oil well during oil construction operation. Because the drilling mud stays in contact with the wellbore the entire time of drilling, the operation cannot be completed without it. 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.
