Wellbore Geometry Component Schema. Defines the "fixed" components in a wellbore. It does not define the "transient" drilling strings or the "hanging" production components.

An ISO 19115 EIP-derived set of metadata attached to ensure the traceability of the WellGeometrySection. |

CurveConductor |
boolean |
Curved conductor? Values are "true" (or "1") and "false" (or "0"). |
|
DiaDrift |
LengthMeasure |
The drift diameter is the inside diameter (ID) that the pipe manufacturer guarantees per specifications. Note that the nominal inside diameter is not the same as the drift diameter, but is always slightly larger. The drift diameter is used by the well planner to determine what size tools or casing strings can later be run through the casing, whereas the nominal inside diameter is used for fluid volume calculations, such as mud circulating times and cement slurry placement calculations.
