Kill Weight Fluid A drilling fluid with a density yielding a hydrostatic pressure equal to or greater than the pressure of the reservoirs exposed in the borehole wall. Kinetic Mixer A section of pipe containing baffles with the purpose of inducing turbulent flow forcing multiple streams into solution. Kitchen That portion of a geologic basin having the temperature and pressure conditions to generate hydrocarbons from source rocks. Klinkenberg Correction Absolute permeability corrected for Klinkenberg effect. The difference between the flow of a gas and a liquid through a reservoir, affecting the permeability.
Gas flow is less impeded by grain surfaces than liquid flow.
A sharp edge at the end of the pipe producing no face. Also referred to as razor edge. The post and hook that are used to hang off a well operated through a rod line. Knuckle Joint A deflection tool, placed above the tools in the work string, that has a ball and socket arrangement which allows the tool to be deflected at an angle. A knuckle joint is sometimes useful in fishing operations because it allows the fishing tool to be deflected to the side of the borehole where a fish may have come to rest.
