Science and Technology of Water Treating

Disciplines: Projects, Facilities, and Construction | Reservoir

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.

Cancellation Policy

All cancellations must be received no later than 14 days prior to the course start date. Cancellations made after the 14-day window will not be refunded. Refunds will not be given due to no show situations.

Training sessions attached to SPE conferences and workshops follow the cancellation policies stated on the event information page. Please check that page for specific cancellation information.

SPE reserves the right to cancel or re-schedule courses at will. Notification of changes will be made as quickly as possible; please keep this in mind when arranging travel, as SPE is not responsible for any fees charged for cancelling or changing travel arrangements.

We reserve the right to substitute course instructors as necessary.


John M. Walsh

Dr. John M. Walsh works for Worley Advisian, having formerly worked at Shell for 21 years, CETCO Energy Services, and Westvaco Paper Company in various areas of water treatment. He is the author of Produced Water volumes 1 and 2, and over 60 papers and presentations.

Walsh has 35 years of experience across a broad range of onshore/offshore, conventional, and unconventional water management applications. He has designed water-treating systems for applications in 18 countries around the world. He has led water treatment technology development, field trials, pilot evaluations, and troubleshooting programs.

Walsh was appointed the Shell Global Subject Matter Expert for Water Treatment. He is versed in reservoir engineering and helped optimize water flood specifications and treatment, mediating between reservoir and facility engineering interests. He is well-connected in the industry having served on the board of directors for SPE, as president and managing director of the Produced Water Society, associate editor for SPE, and as organizing chairman for a dozen workshops and conferences on produced water across the globe.

Having earned a Ph.D. in chemical engineering, together with extensive experience in operating units, Walsh brings a unique combination of fundamental knowledge with firsthand practical experience.
