| Specializations |
| Name | Value Domain | Property / Storage Unit | Description | Required / Default | Type |
|---|---|---|---|---|---|
| Base_Depth | double | Depth m |
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 |
| Box_Number | CODE | NA |
A value that uniquely identifies the container in which the sample is stored. | No |
VARCHAR2(64) |
| Cabinet_Number | int | NA |
The number of the cabinet in which the sample is stored. | No |
NUMBER(10) |
| Core_Segment_Diameter | double | Cylinder_Diameter mm |
A measurement that represents the diameter of the core segment. | No |
NUMBER |
| Core_Segment_Orient_Type | R_Sample_Orientation |
|
The name of the type of rock sample orientation. A rock sample orientation type describes the direction the sample was extracted with respect to the parent sample. Examples include AXIAL, TRANSVERSE, PERPENDICULAR TO BEDDING, PARALLEL TO BEDDING, NO ORIENTATION, RADIAL and VERTICAL | No |
VARCHAR2(64) |
| Dip | double | Plane_Angle deg |
A measurement that represents the dip angle of a bedding surface in the core segment. True dip is measured perpendicular to the line of strike in a vertical plane. Only oriented core allow for measurement of dip directions and they are generally made with a goniometer. | No |
NUMBER |
| Dip_Azimuth | double | Plane_Angle deg |
A measurement that represents the dip direction value observed in the entire core sample. Dip direction is measured in a horizontal plane parallel to maximum dip. Azimuth is measured as a clockwise angle of departure from true (geographic) north, in a horizontal plane. Only oriented core allow for measurement of dip directions and they are generally made with a goniometer. | No |
NUMBER |
| 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) |
| Extraction_Date | DATE | NA |
The date on which the core segment was extracted from the parent core. | No |
DATE |
| GUID | STRING128 | NA |
Globally Unique IDentifier for an instance of a class. USAGE NOTES: There are two cases: 1) GUID is not populated or used; and 2) it is populated with a value that is globally unique. If the GUID is populated there are two means of doing so for a given project: 2a) Seabed automatically generates and populates the GUID when an instance is created (valid only on Oracle based systems); and 2b) the GUID is generated and populated by an application (other than Seabed) on instance creation. Whether Seabed automatically generates GUIDs for a project is determined by the Auto_GUID flag in SDS_Account. Note that techniques 2a and 2b can coexist in the same project. When GUIDs are automatically generated an application can override the automatically generated GUID with its own GUID by simply supplying the GUID value. Applications that generate their own GUIDs and populate the GUID column will function correctly on projects which have automatic GUID generation turned on. | No |
VARCHAR2(128) |
| Id | ID | No_Unit |
Unique identifier for this entity. | Yes |

The name given to any object or data item, e.g. name of Well, name of Field, etc. | No |
VARCHAR2(255) |
| Opr_Sample_Number | CODE | NA |
An identifier, assigned by the well operator, that uniquely identifies the sample. | No |
