Depth in a well — In the oil and gas industry, depth in a well is the measurement, for any point in that well, of the distance between a reference point or elevation, and that point. It is the most common method of reference for locations in the well, and… … Wikipedia
Measured depth — (a) is an imaginary line representing the True vertical depth, while line (b) is the borehole itself, and its length is called the measured depth. In the oil industry measured depth (commonly shortened to MD), is the length of the borehole, line… … Wikipedia

Oil well control — is the management of the dangerous effects caused by unexpected high pressures upon surface equipment of oil or gas drilling rigs. Technically, oil well control involves preventing Formation fluid, usually referred to as kick, from entering into… … Wikipedia
Well kill — A well kill refers to the operation of placing a column of heavy fluid into a well bore in order to prevent the flow of reservoir fluids without the need for pressure control equipment at the surface. It works on the principle that the weight of… … Wikipedia
Directional drilling — A horizontal directional drill in operation Directional drilling (or slant drilling) is the practice of drilling non vertical wells. It can be broken down into three main groups: Oilfield Directional Drilling, Utility Installation Directional… … Wikipedia
Deep well drilling — involves drilling (a well) to a desired deep depth of 10,000 ft or more. Overview Deep well drilling is sometimes more importantly characterized by the requirement of having the drill bit finally positioned within a specified radius of its… … Wikipedia
