| Entity Type | Table |
| Description | An individual, discrete event or period during a fluid analysis to measure properties of a fluid. The pressure and/or temperature may change from one stage to another. Pressure and temperature points during a PVT study are usually captured in this class. |

| Name | Value Domain | Property / Storage Unit | Description | Required / Default | Type |
|---|---|---|---|---|---|
| Activity_State | STRING64 | NA |
The current state, or status, of the activity. Activity state is a refinement of the lifecycle indicator Existence_Kind. For example, a drilling job whose Existence_Kind is "Actual" could have an activity state of "turning to the right", "suspended due to weather", or "tool makeup or breakdown". An activity whose Existence_Kind is "Required" could have State values like "under investigation", "proposed" and "AFE approved". Note: The valid list of activity states will vary from one kind of activity to another, so the values entered into this column are not validated via a lookup table. | No |
VARCHAR2(64) |
| Activity_Template_Id | Activity_Template |
|
The identifier of the activity template which activates or characterizes the Activity. | No |
NUMBER(38) |
| Duration | double | Time s |
The duration of the activity. For planned activities, this would be expected duration. | No |
NUMBER |
| End_Date | DATE | NA |
The date and time at which the activity will end or did end. For planned activities, this would be expected end date. | 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) |
| External_Reference | STRING64 | NA |
A value that is used by an external organization to reference this activity. For example, if an external organization is hired to perform this activity, this column could be used to store the work order or purchase order number that organization uses to reference this activity. | No |
VARCHAR2(64) |
| Final_Pressure | double | Pressure kPa |
The final pressure of the fluid that is being analyzed during this particular fluid analysis stage. | No |
NUMBER |
| Final_Temperature | double | Temperature degC |
The final temperature of the fluid that is being analyzed during this particular fluid analysis stage. | No |
NUMBER |
| Fluid_Analysis_Id | Fluid_Analysis |
|
The identifier of the fluid analysis to which this stage belongs. | Yes |
NUMBER(38) |
| 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 |

NUMBER(38) |
| Initial_Pressure | double | Pressure kPa |
