In that sense, depth is a concept related to elevation, albeit in the opposite direction. It is the most common method of reference for locations in the well, and therefore, in oil industry speech, "depth" also refers to the location itself.īy extension, depth can refer to locations below, or distances from, a reference point or elevation, even when there is no 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.
