• Assess current production performance
  
  
  • current distribution of recovery against expectations
    
    
  • current status and trends of recovery against expectations
    
    
  • current status and trends of reservoir depletion against expectations
     
  • current status and trends of water flood efficiency against expectations
    
    
  • compare performance of different wells or different groups of wells 
    
    
• Identify and prioritize surveillance opportunities
  
  
• Identify and prioritize redevelopment opportunities

Limitations

...

CRM does not pretend to predict pressure and reserves distribution as 3D dynamic model does.

It only provides hints for misperforming wells and sectors which need a further focus.

Technology

...

CRM is built around production data against material balance and require current FDP volumetrics, PVT and SCAL models. 

...

• fast-track
  
  
• based on the most robust input data
  
  
• does not involve full-field 3D dynamic modelling and associtated assumptions

Obviously, CRM does not pretend to predict pressure and reserves distribution as 3D dynamic model does.
