| Entity Type | Table |
| Description | This entity associates a reserve entity with the various classifications it can assume over its lifetime. The classification identifies the probability of recovery, development status, and production status. A reserve entity is a single production entity or group of production entities (real or theoretical) grouped for the purposes of analyzing and forecasting production reserves. A reserve entity may be as small as a single well or as large as desired. Reserves are those quantities of hydrocarbons anticipated to be commercially recoverable by application of development projects to known accumulations from a given date forward under defined conditions. |

| Name | Value Domain | Property / Storage Unit | Description | Required / Default | Type |
|---|---|---|---|---|---|
| Effective_Date | DATE | NA |
The beginning date and time for which the classification of the reserve is effective. | No |
DATE |
| 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) |
| Expiry_Date | DATE | NA |
The date and time on which the classification of the reserve expires. | No |
DATE |
| 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) |
| 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) |
| 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) |
| Reserve_Classification | R_Reserve_Classification |
|
A code, name, or mnemonic that identifies the classification of the reserve entity. The classification includes a level of confidence or probability of the reserve quantity such as "Proven", "Probable", and "Possible". It also includes an indication of Developed or not. If Developed then the Production flag indicates whether the reserves are for producing entities or not. | Yes |
VARCHAR2(64) |
| Reserve_Entity_Id | Production_Entity |
|
The identifier of the production entity (well, field, reservoir, etc) for which reserves are estimated. | 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) |

|---|---|---|---|---|
| Reserve_Classification | R_Reserve_Classification | A code, name, or mnemonic that identifies the classification of the reserve entity. The classification includes a level of confidence or probability of the reserve quantity such as "Proven", "Probable", and "Possible". It also includes an indication of Developed or not. If Developed then the Production flag indicates whether the reserves are for producing entities or not. | Restrict | Yes |
| Reserve_Entity | Production_Entity | The identifier of the production entity (well, field, reservoir, etc) for which reserves are estimated. | Cascade | Yes |
