| Specializations |
| Name | Value Domain / Measurement | Description | Required / Default | Type |
|---|---|---|---|---|
| Base_Depth | double Depth |
The depth measurement that represents the base of the rock sample. This is the deepest or last encountered sample depth along the borehole path and is not related to stratigraphic position. | Yes |
NUMBER |
| Borehole_Id | Borehole |
The borehole that produced these cuttings. | No |

| Box_Number | CODE NA |
A value that uniquely identifies the container in which the sample is stored. | No |
VARCHAR2(64) |
| Cutting_Type | R_Cutting |
A value that represents the type of cuttings sample. The type of cuttings represents the preservation method for the cuttings sample at the well site. Valid values are, WASHED AND DRIED or WET. | No |
VARCHAR2(64) |
| Cuttings_Acquisition_Id | Cuttings_Acquisition |
The wellsite activity that produced this cuttings sample. | No |
NUMBER(38) |
| Existence_Kind | REF_EXISTENCE_KIND NA |
A reference value that describes the state of existence in the lifecycle of the entity, for example, Planned, Predicted, Required, Simulated, and Actual. | Yes Actual |
VARCHAR2(64) |
