Petex: Water Flood Optimisation
Is this to be deleted? It wasn't in the list from Kapil
Context
Large onshore oil field
Naturally Flowing and ESP wells
Water injection (water flood) to maximise recovery
Objectives
Primary Objectives
Reservoir Management and Optimisation
Maximise reserves (recovery)
Optimise production (within above long term strategy)
Secondary Objectives
Field Surveillance and Monitoring
Challenges
The optimisation of recovery requires understanding the dynamic processes inside the reservoir and the ability to assess the impact of actions taken today will have in 10, 20 years’ time.
This requires the appropriate reservoir model to be part of an Integrated Production Model (IPM).
Processes that continually validate the wells and network are well established. However, the validity of the reservoir models are assessed less frequently.
In practice this involves incorporating many different processes, data and disciplines to do successfully.
Solution
Rigorous procedure for validating different reservoir realisations/models.
The integration of a valid numerical reservoir simulation model allows us to incorporate activities including:
Water Injection allocation
Water flood management optimisation
Voidage replacement monitoring
Water breakthrough time prediction
Short/Medium/Long term Forecasting
