• Detection of annular flow
• Corrosion monitoring

       For reservoir perfomance monitoring

• Fluid characteristics
• Water & gas breakthrough
• Thief zones
• Water & gas coning
• Pressure maintenance
• Injection/production profile monitoring

      For production technology

• Flowrate contribution from each reservoir zone
• Measuring the effectiveness of treatment programs
• Cross flow detection
• Productivity indexes
• Formation damage evaluation
• Dump flood injection rates
• Fracture monitoring
• Wellbore capacity monitoring

      Surface Systems:

• Surface SRO System
• Menmory PL system

     Downhole tools:

• Flowmeters
• Temperature
• Capacitance Water Holdup
• Quartz Pressure
