The name of the user responsible for the creation of this entity in the repository. | No |
VARCHAR2(64) |
| MD | double Depth |
Measured Depth of the borehole point. | No |

| From Entity | Link | Description | Implementation Technique | Required |
|---|---|---|---|---|
| Borehole_Point_Parm | Borehole_Point | The borehole point to which the measurement or observation applies. | Cascade | Yes |
| Borehole_Zone | Zone_Base | The point, measured along the borehole, that intersects the base of a zone. | Cascade | Yes |
| Borehole_Zone | Zone_Top | The point, measured along the borehole, that intersects the top of a zone. | Cascade | Yes |
| Correlate_Marker | Correlated_Marker | Two separate markers can be correlated by entering both points, the initial and a correlated marker. The association is commutative so ordering is irrelevant(if Borehole Point A is correlated to Borehole Point B, then Borehole Point B is correlated to Borehole Point A). | Cascade | Yes |
| Correlate_Marker | Initial_Marker | Two separate markers can be correlated by entering both points, the initial and a correlated marker. The association is commutative so ordering is irrelevant(if Borehole Point A is correlated to Borehole Point B, then Borehole Point B is correlated to Borehole Point A). | Cascade | Yes |
| Correlate_Missing_Section | Fault_Or_Unc_Marker | A borehole point that locates an interval or zone of missing section due to faulting, erosion or non-deposition. | Cascade | Yes |
