n: The loss caused by the leakoff of high pressure liquid at the gapping of piston and cylinder liner,valve and valve seat or piston rod and where its sealed.

n: a method of well control in which bottomhole pressure is kept constant when circulation is not possible and gas is migrating up the hole. Bottom- hole pressure is maintained slightly higher than formation pressure while the gas is allowed to expand in a controlled manner as it moves to the surface.

n: A kind of ways of well control when snubbing service,which blowoff or imput same volumic drilling fluids to complement the difference in pressure.

a form of hydrodynamic loading of deep water structures that may lock into a structure’s natural vibration frequency. May include loop currents.

n: an instrument for detecting vortices induced in a fluid stream by a baffle in the fluid stream to measure

abbr: vapor recovery unit.

vapor recovery unit.

abbr: vertical support member.

n: a rock formation that contains openings (vugs). See vug.

n: see vuggy formation.

wing valve on a wellhead.

a method of controlling kicks in which the weight of the kill weight mud is calculated by the difference between the difference of casing and tubing pressure and the volume of fluid increase;followed by injection of the kill weight mud to displace the li
