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 |
Completion design
Completion integrity
Lift mechanism
| 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:
...
| icon | false |
|---|
| 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.
