The key instrument of WRM is Nodal Analysis which leads to a proper selection of WRM activitiesActivities.
The WRM activities are 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 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:
| 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.
