n: the apparatus that measures and recors the volumn of annular fluid , the appratus fixes on the return pipeline.

n: pressure exerted with depth by drilling fluid. Often expressed in pounds per square inch per foot. Also called pressure gradient.

n: the pressure per unit of length that the mud volumn enforces.

n: see hopper.

n: A mud-flow device, also called a jet hopper, in which materials are put into the circulating mud system. The mud hopper is powered by a centrifugal pump that flows the mud at high velocity through a venturi nozzle (jet) below the conical-shaped hopper. Dr

n: when the mud volumn pressure above the layer bearing pressure or encounter the fracture or cave, the mud entirely or partialy loss.

loss of whole mud to the formation.

n: a kinds of graded cup that measure the mud volumn.

n: a very small surge in pressure in the drilling mud as it returns to the surface. In measurement-while-drilling systems, mud pulses carry downhole information-much as radio waves carry sound-for interpretation at the surface.

a pressure pulse in the mud system. Some downhole tools can be controlled by mud pulses and some data is transmitted from bottom hole to the surface via pressure pulses.

n: a lower kelly cock. See drill stem safety valve, lower kelly cock.

n: instrument used to distill oil, water, and other volatile materials in a mud to determine oil, water, and total solids contents in volume-percent.
