Reservoir Pressure Control - Establish bottomhole flowing pressure above critical value while adjusting surface facilities production or injection rates
- Optimize production or injection rates
- Monitor drawdown to reduce probability of sand production
- Avoid long term damage to reservoir, improve recovery efficiency
- Extend life of completion
History Matching - Historical log of pressure data during lifetime of the asset
- Validation of reservoir models
- Update or enhance reservoir understanding
- Update recovery efficiency, estimate of reserves and lifetime of asset
Transient Well Testing - Historical log of bottomhole pressure provides opportunity for transient analysis during planned or unplanned shut-in and drawdown of reservoir pressures
- Transient analysis without intervention
- Early analysis of problem wells without waiting for planned intervention
- Facilitates programming of regular reservoir surveillance to reduce severity or impact of problem wells
- Eliminate deferred production associated with well intervention
Hydraulic Fracturing - Real-time reservoir pressure during hydraulic fracturing operations
- Identify fracture initiation
- Optimize fracture/stimulation duration
- Optimize surface operations, duration and costs
- Enhance safety for pressure control operations
Bottomhole Pressure Data - Real-time access to bottomhole pressure
- Diagnostic pressure data during well intervention, leak-off tests, valve cycling, etc.
- Enhance safety for pressure control operations
- Correct fluid weights during remedial well operations
- Subsurface pressure data for drilling and completion of future wells
