Drilling string capacity, abbreviated as DSC, is the volume of fluid that a drillstring can hold. The drillstring is the assembly of drill pipe, drill collars, and other tools that transmit drilling fluid (mud) and torque to the drill bit. The capacity is an important parameter in drilling operations as it affects the circulation of drilling fluid, which is critical for cooling the bit, carrying cuttings to the surface, and maintaining well pressure.
