4.2.3 CRS Data Object

Knowledge of a well’s location (or points along its trajectory) and reference to it are vital for accurate and safe well-related operations and field development.

A coordinate reference system (CRS) uses a series of numbers to locate entities or objects (such as wellheads) in space. A CRS is a set of axes (a coordinate system (CS)) that is given a location through being related in position and orientation to a specific object. The relationship between the CS and CRS is defined through a datum.
