Definition

The internal diameter of the inner tubular lining installed within a well borehole and acting as the pump chamber casing.

Description

The casing diameter represents the internal diameter of the pump chamber casing, or the casing that is present between the surface level and the installed pump. If the depth of the pump is unknown the casing diameter at the screened locations is collected. Some wells are constructed with no casing, others may have a single casing and still others may have an outer casing and inner casing. In deep wells or when special conditions exist, the casing diameter may become smaller, or telescope as the well deepens.
