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)
Other_Services_Desc STRING255 NA
Description of other services provided for the portrayal or depiction of rock sample properties. Examples include, Photography and X-Ray scanning. No
VARCHAR2(255)
Produced_By STRING64 NA
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)
Row_Number int NA
The number of the row in which the sample is stored No
NUMBER(10)
SDAT_Label int No_Unit
Label used by the security system for entitlements. SDAT is Secure Data Access Technology. No
NUMBER(10)
Sample_Condition STRING64 NA
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

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
Update_Date DATE NA
Date of the most-recent modification to the entity. No
DATE
Update_User STRING64 NA
The name of the user responsible for the last modification to this entity. No
VARCHAR2(64)
