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. To overcome downhole pressure by adding weighting elements to the drilling mud

Well whose orientation and inclination are determined to reach an area not directly below the well.

The depth in a vertical hole at which a deviated or slant hole is started; used in directional drilling

A well is said to “kick” if the formation pressure exceeds the pressure exerted by the mud column

Oil, gas, water, or any combination that enters the borehole from a permeable formation.

Entry of water, gas, oil, or other formation fluid into the wellbore during drilling. It occurs because the pressure exerted by the column of drilling fluid is not great enough to overcome the pressure exerted by the fluids in the formation drilled. If prompt action is not taken to control the kick, or kill the well, a blowout may occur.

A long square or hexagonal steel bar with a hole drilled through the middle for a fluid path. The kelly is used to transmit rotary motion from the rotary table or kelly bushing to the drillstring, while allowing the drillstring to be lowered or raised during rotation
