n: a projecting member run out at an angle from the sides of a portable mast or a land crane to the ground to provide stability and to minimise the possibility of having the mast or the crane overturn.

n: a kinds of kill well method , for the using of the flow rate of fluid in the annular that pumped through pipe above the flow rate of layer fluid that enter into annular, which can repress the overflow into annular.

n: a pump station where one or more tanks are floating on the line. See floating tank.

n: a strip of tube that fixes on the top of large tank.

n: see tandem deck screen shaker.

n: the extent to which the hydrostatic pressure of the mud column exceeds formation pressure.

n: The amount of pressure (or force per unit area) in the wellbore that exceeds the pressure of fluids in the formation. This excess pressure is needed to prevent reservoir fluids (oil, gas, water) from entering the wellbore. However, excessive overbalance c

where the pressure in the wellbore in higher than the pressure in the reservoir.

n: the kill method that the density of drilling fluid volume actually above the needed density of kill fluid.
