v: The natural gas which is consisted of a number of hydrogen sulphide and carbon dioxide kick

n: The correspondent curve of actual time from kicking down to completion and depth. Sometimes it includes the moving time.

n: in drilling operations, gas that returns to the surface with the drilling mud in measurable quantities but does not cause a kick. Increases in background gas may indicate that the well is about to kick or has kicked.

a phenomenon in which fluids are lost to the rock during over-pressured operations, such as found in increased pressures from equivalent circulating density operations, and then flow back when pressure is reduced. This may be confused with a kick.

n: an uncontrolled flow of gas, oil, or other well fluids into the atmosphere. A blowout, or gusher, occurs when formation pressure exceeds the pressure applied to it by the column of drilling fluid. A kick warns of an impending blowout. See kick.

an uncontrolled release of fluids from a well.

the angle of the inclination in the kickoff section when describing a deviated well.

n: 1. forcing gas back into a formation by pumping into the annulus from the surface.2. any pumping procedure in which fluid is pumped into the well against pressure.

forcing fluids in the pipe into the formation at a pressure higher than the pore pressure and sometimes higher than the fracturing breakdown pressure. Used to displace a kick out of the pipe when wellbore and wellhead pressure limits permits.

n: the amount of pressure that, when applied inside a string of casing, causes the wall of the casing to fail. This pressure is critically important when a gas kick is being circulated out, because gas on the way to the surface expands and exerts more pressure than it exerted at the bottom of the well.

n: The pressure leading to collapsing of the casing.

n: a procedure whereby the formation immediately below the casing shoe is subjected to a pressure equal to the pressure expected to be exerted later by the drilling fluid or by the drilling fluid and the back-pressure created by a kick. See leakoff test.

a LOT or an FIT test (check specifics for details),a pressurized test after primary cementing to make sure the bottom most seal with the formation will handle pressures needed for drilling the rest of the well.

n: a device with an orifice installed in a line to restrict the flow of fluids. Surface chokes are part of the Christmas tree on a well and contain a choke nipple, or bean. with a small-diameter bore that serves to restrict the flow. Chokes are also used to control the rate of flow of the drilling mud out of the hole when the well is closed in with the blow-out preventer and a kick is being circulated out of the hole. See adjustable choke. bottomhole choke. positive choke.

n: A device incorporating an orifice that is used to control fluid flow rate or downstream system pressure. Chokes are available in several configurations for both fixed and adjustable modes of operation. Adjustable chokes enable the fluid flow and pressure

a device used to create a controlled pressure drop and allow some expansion of the gas. A choke holds a back pressure on the well fluids, controlling the expansion rate of the gas. It is useful for optimizing natural gas lift in oil wells with sufficient
