multi-service valve.

n: the method that mud balance method measure the volume density of shale debrics to indirectely determine abnomal layer pressure.

n: according to various demand, mud formula that makes up various chemical agent and material .

n: the process of pumping mud downward to the bit and back up to the surface in a drilling or workover operation. See normal circulation, reverse circulation. mud cleaner n: a cone-shaped device, a hydro-cyclone, designed to remove very fine solid particles from the drilling mud.

n: the procedure that pump the mud through the bit and then reture to the ground when drilling or workover.

n: the pressure that the weight of mud volume enforce to the bottom of horebore.

n: A graduated cup used to take samples and to crudely measure volumes of mud for testing at the rig. A mud cup is used primarily with the Marsh funnel to measure one quart of flow out of the funnel. It is also used as a container for performing simple pilot

a graduated cup used to sample mud and fill the Marsh funnel.

n: see mud weight.

n: The mass per unit volume of a drilling fluid, synonymous with mud density. Weight is reported in lbm/gal (also known as ppg),kg/m3 or g/cm3 (also called specific gravity or SG),lb/ft3 or in hydrostatic gradient, lb/in2/ft (psi/ft) or pptf (psi/1000 ft).

the specific gravity of the mud expressed in lb/gal, kg/m3, etc.

n: a device that automatically records the weight or density of drilling fluid as it is being circulated in a well.

n: the mud quality of unite volume.

n: the volumn of strings displace the same volumn of mud.

n: the degree that displace the cement volumn in the annular when well cementing.
