n: the length ratio of fluid in the holebore after discovery overflow and shut in.

v: 1. to bring a well into production;used most often when gas is injected into a gas lift well to start production. 2. in workover operations, to swab a well to restore it to production. 3. to deviate a wellbore from the vertical, as in directional drilling.

n: the degree of fluid increase in the mud pool and casing pressure closed (CPC) arised from overflow, it often inflects the difficuties of well control.

n: the amount of pressure that the casing seat can take without fracturing. It is calculated from the height and volume of the kick in the well.

n: after overflow and shut in, the maximum difference the fluid density in the hole from the equivalent density that converted by casing allowable pressure and volume pressure in the holebore unless it happens overflow.

n: a special tool that fixes the bottom of drilling volume and uses it to change the direction of the hole in directional well drilling.


a fishing tool that decentralizes the retrieving tool. Commonly used in gas lift.

v: 1. in drilling, to control a kick by taking suitable preventive measures (e.g., to shut in the well with the blowout preventers, circulate the kick out, and increase the weight of the drilling mud). 2. in production, to stop a well from producing oil and gas so that reconditioning of the well can proceed. Production is stopped by cir- culating a kill fluid into the hole.

v: To stop a well from flowing or having the ability to flow into the wellbore. Kill procedures typically involve circulating reservoir fluids out of the wellbore or pumping higher density mud into the wellbore, or both. In the case of an induced kick, where

a term used to describe various methods to stop flow from a well. Commonly pumping a kill weight fluid into a well to create an overbalance into the formation.

n: the mud that control well blowout or overflow.

n: the mud density that control well blowout or overflow.

n: the speed, or velocity, of the mud pump used when killing a well. Usually measured in strokes per minute, it is considerably slower than the rate used for normal operations.

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

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.
