| Name | Well_Completion |
|---|---|
| Entity Type | Table |
| Description | The logical representation of an assembly of equipment that enables production from reservoirs into a production string. At a given point in time, one well completion can span many perforation intervals, but a perforation interval can flow into only one completion. Additionally, one completion can span multiple reservoirs, and a single reservoir can flow into multiple completions. Finally, a well completion has to be able to isolate a fluid flow and measure it continuously. |

| Name | Value Domain | Property / Storage Unit | Description | Required / Default | Type |
|---|---|---|---|---|---|
| Base_Interval_MD | double | Depth m |
The current measured depth from the surface to the base of the completion | No |
NUMBER |
| Borehole_Id | Borehole |
|
The identifier of the borehole where the completion is located | Yes |
NUMBER(38) |
| Casing_String_Id | Casing_String |
|
The identifier of the production string (Casing String) into which the well completion directs the flow of fluids. This is only used in situations where there is annular flow. | No |
NUMBER(38) |
| Driller_Reference_MD | double | Depth m |
The reference depth entered by the driller for this completion. | No |
NUMBER |
| 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) |
| Facility_Equipment_Flag | CODE | NA |
A flag to denote whether a given facility should be treated as a facility (F), a piece of equipment (E) or both (B). A facility labeled as F represents a role (e.g. ESP) played by physical piece(s) of equipment and would not have attributes like serial number, manufacturer etc. It can be related to the physical pieces(s) of equipment using Facility_Composition. The individual physical pieces can be replaced if they need to be, without changing the facility. A Facility labeled as E represents a physical piece of equipment (e.g. Drill Pipe) which is normally used in the context of an activity and would not be permanently installed. A facility labeled as B represents both a physical piece of equipment as well as the role played by it. If this kind of Facility is connected in the network and stops working and needs to be replaced, then all connections to this Facility are expired and new connections are made to the replacement facility. | No |
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) |

VARCHAR2(64) |
| Isolation_Location | CODE | NA |
When a completion is isolated from the rest of the borehole, this value specifies whether the isolation is above the completion, below the completion, or both. Valid values are above, below, or both. | No |
