A set of Subsurface Production Operational activities towards execution of Field Development Plan.
The key instrument of WRM is Nodal Analysis which leads to a proper selection of WRM Activities.
The WRM Activities are These activities are usually classified by the purpose:
Operational HSE | Production acceleration | Production Cost | Sweep efficiency | ||||||
---|---|---|---|---|---|---|---|---|---|
Infill drilling | Production targets |
designing & maintaining integrity | designing |
---|
& maintaining integrity | Increasing (Drilling) |
---|
Optimising (Conformance control) | |||||||||
---|---|---|---|---|---|---|---|---|---|
Infill drilling | Side-tracks | Flow Stimulation | Flow Shut-off | EOR |
The above activities are WRM Activities are facilitated by four following execution mechanisms:
Subsurface | Surface | |||
---|---|---|---|---|
Drilling & Completion | Workovers | Wireline |
facilities and procedures |
---|
Prioritizing of WRM Activities is based on technical feasibility and economics, provided by WRM Activity Value @model.
This particularly leads to the four following major asset challenges:

Which wells to change the flow rate and whether increase or decrease ? | |
4 |

What fluid and at what time to inject ? |
...
5 | Is there a bottleneck in surface infrastructure and whether it needs update ? |

The answers to these questions are provided by playing the various scenarios over the calibrated full-field flow model.
