  1. Monitoring Produced Water: Case Study Challenges and Successes Presentation by: Gerard Cooke www.envirotechsystems.com www.advancedsensors.co.uk info@envirotechsystems.com sales@envirotechsystems.com 17327 Norwell Drive Covington, LA 70435 Phone: 985-809-6480

  2. History • Major Oil Company in the GoM was facing issues with water treatment equipment at multiple facilities • Existing monitoring equipment not working satisfactorily • One of the facilities was issued an NPDES discharge violation after a sheen resulted from an overnight equipment failure • Looking for ways to improve the water treatment process and early detection

  3. Challenges • Know what is going on! • Make changes and improvements • Trust the data • React to what is known • Use data to make process control decisions • Automate the process

  4. Reliability and Trust Cleaning • Cleaning has always been a major problem with monitors • “Oil in water monitors do not work” • Customer was not convinced monitor could automatically clean • Over time trust was built up with automatic cleaning leading to less and less lab samples • glass clean_med2.wmv

  5. EquipmentSelection • Factors to Consider • Reliability • Dependability • Monitoring at Multiple Points in the System • Side-Stream vsIn-Line

  6. Installation

  7. Early Data

  8. Later Installations

  9. Data • Graph represents 17 months of data for discharge (Oct ‘11 – Feb ‘13)

  10. Successes Zero Noncompliance Violations Since Installation • Since the monitors have been deployed in the Gulf of Mexico, the oil company has had zero NPDES violations • Similar configuration now deployed on 7 platforms in GoM with more to follow in 2013

  11. Conclusion • Monitoring multiple locations not only insures no violations but provides early detection indicators and cost saving • Cost saving not only from zero violation but also from process monitoring i.e. chemical usage optimisation
