| Entity Type | Table |
| Description | Analogous to PPDM 3.7 SP_MINERAL_ZONE. A land zone defines the subsurface component of the land description. For example, subsurface rights that have been granted to the holder of a mineral agreement. The interval is defined by either a formation top/base or depth top/base or a geologic layer. |

| Name | Value Domain | Property / Storage Unit | Description | Required / Default | Type |
|---|---|---|---|---|---|
| Base_Depth | double | Depth m |
The depth at the base of the zone. | No |
NUMBER |
| Base_Geologic_Surface_Id | Geologic_Surface |
|
The geologic surface boundary that represents the base of the zone. | No |
NUMBER(38) |
| Excluded_Flag | boolean | NA |
A flag that indicates that this subsurface zone is not included in the land mineral rights. This information is generally not provided by the agreement, but may be added to facilitate queries as needed. If the flag is set to True, then this zone is excluded. If the flag is set to False or NULL then the zone is included in the land mineral rights. The default value is False. | No 0 |
NUMBER(1) |
| 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) |
| Geologic_Layer_Id | Geologic_Layer |
|
The identifier of a geologic layer. If a land zone is described in terms of a named formation or zone, this can be used to store the reference to it. | 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) |
| Produced_By | STRING64 | NA |

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) |
| Top_Depth | double | Depth m |
The depth at the top of the zone. | No |
NUMBER |
| Top_Geologic_Surface_Id | Geologic_Surface |
|
The geologic surface boundary that represents the top of the zone. | No |
NUMBER(38) |
| Update_Date | DATE | NA |
Date of the most-recent modification to the entity. | No |
