n: The process that drilling fluid is pumped from the pool and returns to the pool through standpipe, drilling hose, drilling string ang bit.

n: The hose dismounted from the standpipe is used as the exit of drill fluid,cuttings or core.

n: a line through which drilling mud travels from the mud pump to the standpipe on its way to the wellbore.

n: A high-pressure pipeline between the exit of drill pump and the standpipe

n: the instrument installed on the standpipe and used to disply the pressure of the fluid in the drilling pipe

n: see rotary hose.

n: A large-diameter (3- to 5-in. inside diameter),high-pressure flexible line used to connect the standpipe to the swivel. This flexible piping arrangement permits the kelly (and, in turn, the drillstring and bit) to be raised or lowered while drilling flui

n: the pressure exerted by the mud pump (and read on the standpipe or drill pipe pressure gauge) when the pumps speed is reduced to a speed lower than that used during normal drilling. A kill rate pressure or several kill rate pressures are estab- lished for use when a kick is being circulated out of the wellbore. Also called p-low.

n: the delivery capacity pressure of pump that circulates the kill well fluid and discharges the overflow or suppresses well blowout.

n: a steel-reinforced, flexible hose that is installed between the standpipe and the swivel or top drive. It conducts drilling mud from the standpipe to the swivel or top drive. Also called the kelly hose or the mud hose.

n: a reinforced flexible tube that conducts drilling fluid from the standpipe to the swivel. also calledkelly hose or mud hose.

the connection from the mud pump to the stand pipe. Also called the mud hose or kelly hose.

n: a vertical pipe rising along the side of the derrick or mast, which joins the discharge line leading from the mud pump to the rotary hose and through which mud is pumped into the hole.

n: A rigid metal conduit that provides the high-pressure pathway for drilling mud to travel approximately one-third of the way up the derrick, where it connects to a flexible high-pressure hose (kelly hose). Many large rigs are fitted with dual standpipes so

the pipe in the derrick that delivers mud to the kelly hose.
