| 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 |
| Borehole_Id | Borehole |
|
The identifier of the borehole that produced these cuttings. | No |
NUMBER(38) |
| 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) |
| 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 identifier of 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) |
| 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 |
NUMBER(38) |
| Insert_Date | DATE | NA |
Date the entity was created in the repository | No |
DATE |
| Insert_User | STRING64 | NA |
The name of the user responsible for the creation of this entity in the repository. | No |
VARCHAR2(64) |
| Name | ENTITY_NAME | NA |
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 |
VARCHAR2(64) |
| Original_Source | STRING64 | NA |
The name of the person, Organization or project source that originally provided this entity, e.g. "IHS-EnergyData" or "FinderUpper Stratton Deeper Pool 15" | No |
VARCHAR2(64) |

The name of application role that created the entity, for data created programmatically. | No |
VARCHAR2(64) |
| Rack_Number | int | NA |
The number of the rack in which the sample is stored. | No |
NUMBER(10) |
| Remarks | STRING2000 | NA |
Any type of remarks added to an entity instance. | No |
VARCHAR2(2000) |

A textual description of the condition of the sample | No |
VARCHAR2(64) |
| Sample_Container | STRING64 | NA |
The container in which the cuttings were received. | No |
VARCHAR2(64) |
| Sample_Quality | R_Sample_Quality |
|
A value that describes the visually estimated quality of the core. Valid values are: GOOD, FAIR, POOR. A good cuttings quality implies the sample is representative of the formation and should provide accurate analysis. A fair core quality implies some damage during the sample acquisition process but suitability for analysis. A poor core quality implies significant damage or contamination and a sample that is unsuitable for most analysis. | No |
VARCHAR2(64) |
| Sample_Volume | double | Volume m3 |
The volume of cuttings received. | No |
NUMBER |
| Source | STRING64 | NA |
Name of the person or organization responsible for this entitys E and P content and quality. Not the data technologist or IT expert creating the entity, for which see IT_Object.Insert_User and Update_User. | No |
VARCHAR2(64) |
| Storage_Location | STRING64 | NA |
The name of the location where the sample is stored. | No |
VARCHAR2(64) |
| Sub_Type | Meta_Entity |
|
Sub type of Rock_Sample | No |
VARCHAR2(30) |
| Top_Depth | double | Depth m |
The depth measurement that represents the top of the rock sample. This is the shallowest or first encountered sample depth along the borehole path and is not related to stratigraphic position. | Yes |
NUMBER |
