Columns

[Previous] [Next] [Top]
NameValue DomainProperty /
Storage Unit		DescriptionRequired /
Default		Type
Avg_Deep_Resistivity double Resistivity
ohm.m		 The average value for deep resistivity in this zone. 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)
Gross_Sand double Length
m		 The gross thickness of reservoir lithology not accounting for reservoir quality. No
 NUMBER
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)
Litho_Zone_Desc STRING64 NA
 A borehole zone may encompass many different lithologies. Litho_Zone_Desc provides a description of the entire set of encountered rock types across the zone. It may be a list or a short narrative on how the lithologies relate. Typical entries include values like, Sand Shale Sand, Interlaminated sands and shales, Shaly sands and Sandy shales, etc. A more complete description of the breakdown of individual components is found in Litho_Zone_Fraction for this zone. No
 VARCHAR2(64)
Measurement_Date DATE 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 rock 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)
Net_Sand double Length
m		 The net thickness of reservoir lithology including only intervals with reservoir quality. 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)
Permeability double Permeability
mD		 The permeability of the rock No
 NUMBER
Permeability_Height double Integrated_Permeability
mD.m		 The product of the permeability and the length of the permeable section across the zone. This value is often called Kh. No
 NUMBER
Porosity double Porosity
m3/m3		 The porosity of the rock No
 NUMBER
Produced_By STRING64 NA
 The name of application role that created the entity, for data created programmatically. No
 VARCHAR2(64)
Remarks STRING2000 NA
 Any type of remarks added to an entity instance. No
 VARCHAR2(2000)
Rock_Pty_Zone_Id Borehole_Zone
The zone, from top to bottom, that defines the limits of the general properties in this borehole. Yes
 NUMBER(38)
SDAT_Label int No_Unit
 Label used by the security system for entitlements. SDAT is Secure Data Access Technology. No
 NUMBER(10)
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)
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)
Version STRING255 NA
 The form or variant of the entity. Yes
1		 VARCHAR2(255)
Zone_Interval_Porosity R_Porosity
A value that represents the predominant porosity type of the borehole zone. Examples include Intergranular, Fenestral, Fracture. No
 VARCHAR2(64)
