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 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 WRM Activities are facilitated by following execution mechanisms:
| Subsurface | Surface | |||
|---|---|---|---|---|
| Drilling & Completion | Workovers | Wireline | EOR 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 following major asset challenges:
| 1 | Where to drill the new well or side-track and how to completion it ? |
|---|---|
| 2 | Which wells to workover and how ? |
| 3 | 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.
