Thirty years ago, the Colman-Thew paper was published describing the geometry and performance characteristics of a cyclone device for removing oil drops from water.  Uptake of this technology occurred immediately throughout the industry.

In this SPE Webinar, the fundamental science behind the hydrocyclone will be discussed together with practical considerations of model selection and implementation within a separation process.  Field experience related to separation performance, detection and prevention of fouling will also be covered.


John M. Walsh, SPE
, is a principal engineer with GHD, an engineering and consultancy company specializing in water treatment. He recently retired from Shell where he was the global subject matter expert in upstream water treating.

He has more than 20 years’ experience in the E&P industry, having worked in Shell technical centers for half of his career and in operating assets for the other half. He has designed water treating system, and 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 waterflood, polymer flood, steamflood, sour hydrocarbons, and unconventional hydrocarbons.

Walsh served on the SPE Board of Directors as the technical director for the Projects, Facilities, and Construction discipline. He earned a PhD in chemical engineering from Johns Hopkins University.
