Produced Water Treatment Fundamentals

This skill module covers the following topics:
• Explain the technologies that govern the design and performance of produced water treatment systems
• Explain the basic chemistry and unique characteristics of produced water, dissolved gases, dissolved minerals, dissolved and dispersed hydrocarbons, extraneous chemicals, etc.
• Define retention time, fluid velocity, nozzle sizing, inlet device design (cyclonic inlets), and outlet nozzle vortex control for primary separators
• Identify where, why, and how deoiling hydrocyclones are used for produced water treatment
• Define the designs, operating principles, capabilities, and weaknesses of dissolved gas flotation, induced gas flotation, and mechanical flotation
• Explain the operating principles for nutshell media bed filtration
• Describe the basics of membrane filtration technology
• Define the common methods for oilfield water disposal or injection
• Explain how to use Silt Density Index (SDI), NACE TMO-173 filtration tests, TOG measurements, and/or TSS measurements to define water quality
• Discuss the purposes and capabilities for the seawater injection system’s front-end technologies
• Identify the basic configuration of the media bed filter’s internals and the operating parameters for multi-media and nutshell media filters
