Default
Type
Aquifer_Zone_Id Borehole_Zone
The zone, from top to bottom, that defines the limits of the aquifer in this borehole. Yes
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 date and time when the measurement activity for this set of properties occurred. No
DATE
Measuring_Activity_Id Generic_Activity
The activity that recorded the aquifer properties No
NUMBER(38)
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)
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)
Permeability double Permeability
mD
The permeability of the rock No
NUMBER
Porosity double Porosity
m3/m3
The porosity of the rock No
NUMBER
Produced_By STRING64 NA

VARCHAR2(64)
Transmissivity double Area_Per_Time
m2/s
The transmissivity of the Aquifer. Transmissivity T is the product of hydraulic conductivity k and aquifer thickness $h-b$ ($=$ level $-$ basis). Transmissivity between two compartments is the average of the two transmissivities. Average can be arithmetic, geometric or harmonic. No
