| Name | Litho_Zone_Fraction |
|---|---|
| Entity Type | Table |
| Description | A lithology that is a unified part of the borehole zone for this property set. This lithologic fraction or component should be recognizable in and of itself. Examples include the sandstone part of a laminated sand and shale sequence, a coal seam, or the dolomite facies in a carbonate interval. |

| Name | Value Domain | Property / Storage Unit | Description | Required / Default | Type |
|---|---|---|---|---|---|
| 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) |
| Fraction_Distribution | CODE | NA |
A description of the association of this lithologic fraction to the litho zone as a whole. The distribution cannot have location references such as depth intervals or terms like above or overlying. It should describe the general distribution and boundaries of the various rock types such as dispersed, inter-laminated, or gradational. | No |
VARCHAR2(64) |
| Fraction_Percentage | double | Percent % |
Percentage of the lithologic fraction in the borehole zone. | No |
NUMBER |
| 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) |

VARCHAR2(64) |
| Lithologic_Observation | int | No_Unit |
A number that identifies the rank of the lithologic fraction for a particular zone. I.e., if this is the 1st lithologic fraction for the zone, the value should be 1. If it is the 2nd lithologic fraction, the value should be 2, etc. This ordering is arbitrary and does not imply any spatial relationship such as above vs. below, or older vs. younger. | No |
NUMBER(10) |
| Lithologic_Zone_Part | R_Rock_Sample_Fraction |
