Type
Azimuth double Plane_Angle
deg
The angle of the line running from the borehole to the source measured clockwise from north. No
NUMBER
Borehole_Seismic_Act_Id Borehole_Seismic_Acq_Act
The borehole seismic survey for which this source was an energy source for the survey. Yes
NUMBER(38)
Elevation double Length
m
The source elevation above the vertical reference specified in the depth coordinate system defined for the borehole seismic survey. 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)
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

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)
Offset double Length
m
The lateral distance of the source from the borehole in the direction given by Azimuth. No
NUMBER
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)
Position_Id Position
The spatial position of the seismic energy source used to acquire the borehole seismic survey. No
