| Name | Value Domain | Property / Storage Unit | Description | Required / Default | Type |
|---|---|---|---|---|---|
| Bottom_Hole_Pressure | double | Pressure kPa |
The pressure at the bottom of the borehole. | No |
NUMBER |
| Bottom_Hole_Temperature | double | Temperature degC |
The temperature at the bottom of the borehole. | No |
NUMBER |
| Casing_Pressure | double | Pressure kPa |
The pressure inside the casing upstream of the casing choke that is representative for the flow period. | No |
NUMBER |
| Casing_Temperature | double | Temperature degC |
The temperature inside the casing upstream of the casing choke | No |
NUMBER |
| Choke_Size | double | Cylinder_Diameter mm |
The choke size being used when the event took place. | No |
NUMBER |
| Event_Id | Event |
|
Reference to the event/risk for which the environment is defined. | Yes |
NUMBER(38) |
| 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) |
| Flow_Rate | double | Flowrate m3/h |
The volume quantity of the material that is flowing during the reporting period. | No |
NUMBER |
| Flowline_Pressure | double | Pressure kPa |
The pressure of the flow line that is representative for the flow period. If you are producing from the casing, the flowline pressure is the pressure inside the conduit downstream of casing choke, and before the separator. If you are producing from the tubing, the flowline pressure is the pressure inside the conduit downstream of tubing choke, and before the separator. | No |
NUMBER |
| Flowline_Temperature | double | Temperature degC |
The temperature of the flow line that is representative for the flow period. If you are producing from the casing, the flowline temperature is the temperature inside the conduit downstream of casing choke, and before the separator. If you are producing from the tubing, the flowline temperature is the temperature inside the conduit downstream of tubing choke, and before the separator. | No |
NUMBER |
| GOR | double | Gas_To_Liquid_Ratio m3/m3 |
The gas to oil ratio when the event took place. | 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 |
