| Entity Type | Table |
| Description | A granular substance (sand grains, aluminum pellets, or other material) that is carried in suspension by the fracturing fluid and that serves to keep the cracks open when fracturing fluid is withdrawn after a fracture treatment. (MMS). |

| 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) |
| Fine_Impurity_Percent | double | Percent % |
A property of the Proppant to indicate its Quality (fines and impurities). A high percentage of fines or impurities can reduce the proppant pack permeability. | 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) |
| Grain_Roundness_Factor | CODE | NA |
A property of Proppant to indicate the Sphericity or Roundness of the Grain. When grains are round and about the same size, stresses on the proppant are more evenly distributed, resulting in higher loads before grain failure occurs. | No |
VARCHAR2(64) |
| Grain_Size | double | Cylinder_Diameter mm |
A property of proppant to indicate the grain size. Proppants with large grain sizes provide a more permeable pack. | No |
NUMBER |
| Grain_Size_Distribution | CODE | NA |
A property of the Proppant to indicate the distribution of grain size. If the grain size distribution is such that the mesh range contains a high percentage of smaller size grains, the proppant pack permeability and therefore the conductivity will be reduced. Minimizing the mesh range will increase the permeability. | No |
VARCHAR2(64) |
| Grain_Strength | double | Strength kPa |
Ability to withstand closure stress of the fracture. | No |
NUMBER |
| Id | ID | No_Unit |
Unique identifier for this entity. | Yes |

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 |

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 |
