A set of Subsurface Production Operational activities towards execution of Field Development Plan and
Operational Safety | Production acceleration | Production Cost | Sweep efficiency | Displacement efficiency | ||||
---|---|---|---|---|---|---|---|---|
Flowrates | Infill drilling | Completion\Lift design & integrity | Increasing well-reservoir contact | Optimising well-reservoir contact (Conformance control) | ||||
New wells | Side-tracks | Flow Stimulation | Flow Shut-off | EOR |
The above activities are facilitated by four execution mechanisms:
Subsurface | Surface | ||
---|---|---|---|
Drilling & Completion | Workovers | Production/injection Rate Optimisation | EOR flooding facilities and procedures |
This leads to the four major asset challenges:
1. Where to drill the new well or side-track and how to complete 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 ? 6. 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.
