Temperature lower than expected (reservoir)
After drilling and testing the well, the temperatures might be below what was estimated during conception phases and result in overall low system performances from the beginning of the project. This risk is generally accounted for during project development phase using uncertainty analysis and modelling of the doublet based on exploration data collected.
Informations
- Category: Risks due to subsurface uncertainties
- Id: D-3
-
Phases:
- Drilling / Testing
-
Consequences:
- Economic / Performance / Acceptability
Mitigation
-
Prevention:
- Use of cement with increased heat insulation properties
- Additional investigation early in the project
-
Monitoring:
- Accurate collection and interpretation of temperature data measured in existing wells to provide information for temperature forecast
- Doing new temperature measurements in existing wells to provide information for temperature forecast
-
Corrective measures:
- Increase of the flow rate
- Adaptation of the drillpath to reach multiple targets - drill further
