Defining 'Tag & Tag Groups' is crucial for understanding their purpose and proper usage, similar to signal definitions.
Well Life Cycle
Well Life Cycle is a set of major phases that are significant to regulators and/or business stakeholders. Well Life Cycle may apply to a well or its components.
- Operating
Operating is the activities of the Well Life Cycle while the well or component can perform its intended Role. It includes periods where the well is temporarily shut in.
- Closing
Closing is the set of activities of the Life Cycle to make the well or component permanently incapable of any Role. - Closed
Closed is the phase of the Life Cycle when the well or component is permanently incapable of performing any Role.
Well Type
Well Type is the current purpose, whether planned or actual. The value of Well Type may change over the Well Life Cycle.
- Produce
Well Type of Produce is to extract products for commercial purposes.
- Inject
Well Type of Inject is to force fluids into the reservoir to enhance recovery of hydrocarbons.
- Produce/Inject
Well Type of Produce/Inject can both produce and inject, either cyclically or simultaneously.
- Observe
Well Type of Observe is for the purpose of monitoring subsurface conditions.
- Dispose
Well Type of dispose is for the purpose of permanent injection of a waste fluid into a reservoir.
- Storage
Well Type of Storage is for the purpose of injection and subsequent recovery of a fluid into / out of a reservoir.
- Supply
Well Type of Supply is for the purpose of obtaining fluids for operations.
Well Condition
Well Condition is the operational state relative to the Well Type.
The change in value is usually based on business rules that may vary by operator or regulator. For example, a producing well that is undergoing routine service or testing for a few days may or may not be considered Inactive. Idle may be referred to as suspended, temporary abandonment, temporary cessation, etc. in some areas.
- Active
The Active Condition describes a well or component that is fulfilling its Type.
- Inactive
The Inactive Condition describes a well or component that is not fulfilling its Type.
- Shut In
Shut In is an intentional pause in operation that does not require regulatory notification. Shutting in involves closing valves or shutting off pumps that are required to accomplish the Type.
- Idle
Idle is an intentional pause in operation that requires regulatory notification. Idle involves closing valves or shutting off pumps that are required to accomplish the Type.
- Abandoned
The well or component is permanently incapable of fulfilling its Type
Well Product
Well Product is the physical product(s) that can be attributed to any well component.
- Oil
- Water
- Gas
- Condensate
- Steam
Well Flow
Well Flow is the flow direction of the wellhead stream. The value can change over the life of the well.
- Inflow
- Outflow
- Static
- Dual Flow
Well Lift Method
Well Lift Method is the method applied on the well to lift the product. The facet value can change over the life of the well
- Electrical Submersible Pump
- Sucker Rod Pump
- Gas Lift
- Plunger Lift
- Jet Pump
- Natural Flow
Failures
Failures is a set of events that prevent a well or component from fulfilling its role. Failures may apply to a well or its components.
- Well Failure
Describes a generic failure of the well without giving any more information.
- Pump Failure
Describes the inability of the pump component to fulfill its purpose.
