Science and Technology of Water Treating

Projects, Facilities and Construction Reservoir Descriptions and Dynamics

Course Description

This course provides a fundamental understanding of the science and practical applications of water treating. It presents the fundamental mechanisms behind various water treating equipment and processes, and gives practical experience from dozens of water treating facilities from around the globe.

Throughout the course, field experiences, practical issues, and field performance of equipment is analyzed and explained in terms of surface science, chemistry and engineering principles. The scientific aspects of water treating are presented in a practical down-to-earth manner that can be understood with little prior study, and can be immediately implemented in the field. The full project life cycle is covered from concept selection to front end engineering, detailed design, operation, and trouble shooting.


  • Characterization of oil/water/gas for water treating
  • Equipment selection and performance
  • Process engineering and process line-ups
  • Chemical treating
  • Operations, monitoring, and surveillance
  • Troubleshooting

Course Length

2 Days

Why Attend

Water treating is becoming increasingly important for maintaining the license to operate, as a component of DBOO project delivery, and for developing IOR/EOR projects.

Who Attends

The course is intended for process, facilities, and chemical engineers involved in either designing or troubleshooting water-treating systems. Both onshore and offshore facilities are presented.

Special Requirements

Attendees should have a basic understanding of process, facilities, or chemical engineering.


Engineers are responsible for enhancing their professional competence throughout their careers. Licensed, chartered, and or/ certified engineers are sometimes required by government entities to provide proof of continued professional development and training. Training credits are defined as Continuing Education Units (CEUs) or Professional Development Hours (PDH)

Attendees of SPE training courses earn 0.8 CEUs for each day of training. We provide each attendee a certificate upon completion of the training course. 1.6 CEUs awarded for this 2-day course.

John M. Walsh

This session will be taught by Experts from CETCO. 

John M. Walsh is a consultant, currently working for CETCO Energy Services. He recently retired from Shell where he was the global subject matter expert in the area of upstream water treating. He has more than 30 years’ experience overall, and 20 years’ experience specifically in the E&P industry dealing with water treatment. He worked in technical centers for half of his career and in operating assets for the other half. He has designed water-treating systems, and provided troubleshooting support to assets all over the world. He has experience in nearly all areas of water treating for the oil and gas industry including conventional produced water treating systems, and water treating for water flood, polymer flood, steam flood, sour hydrocarbons, and unconventional hydrocarbons.   

Having earned a PhD in chemical engineering, together with extensive experience in operating units, he brings a unique combination of fundamental knowledge with first hand practical experience. He has presented more than 40 papers on the subject of produced water treating at various conferences and workshops. He recently served on the Board of Directors of SPE as the technical director for the Projects, Facilities, and Construction discipline. He currently serves on the organizing committee for Water Handling Global Integrate Workshop Series.
