The non-contextual content of a WITSML Wellbore object. This is a pointer to the parent wellbore. No parent = starts from top. Operator borehole number. API suffix. Government assigned number. POSC wellbore status. POSC wellbore purpose. Type of wellbore. POSC wellbore trajectory shape. Date and time of wellbore kickoff. True ("true" of "1") indicates that the wellbore has acheieved total depth. That is, drilling has completed. False ("false" or "0") indicates otherwise. Not given indicates that it is not known whether total depth has been reached. The current measured depth of the borehole. If status is plugged, indicates the maximum depth reached before plugging. The current true vertical depth of the borehole. If status is plugged, indicates the maximum depth reached before plugging. Kickoff measured depth of the wellbore. Kickoff true vertical depth of the wellbore. Planned measured depth for the wellbore total depth. Planned true vertical depth for the wellbore total depth. Planned measured for the wellbore total depth - with respect to seabed. Planned true vertical depth for the wellbore total depth - with respect to seabed. Target days for drilling wellbore.
