Oil, Gas & Water Separation
How a production facility splits the well stream into oil, gas and water: separation principles, two- and three-phase vessels, internals, level, pressure and interface control, emulsion treatment, and the upsets an operator must recognise and act on. For production operators, technicians and the engineers who support them.

What you'll learn
- Explain why separation is the heart of production processing and what every downstream system inherits from it.
- Describe how density difference, residence time and coalescence govern separator performance.
- Distinguish two-phase and three-phase separators, and vertical and horizontal vessels, and say which duty each suits.
- Identify the main separator internals — inlet devices, weirs, vortex breakers and demisters — and explain what each contributes.
- Apply level, pressure and interface control, and manage emulsions through demulsifier dosing and bottle testing.
- Diagnose common upsets — foaming, slugging, liquid carryover and gas blow-by — and choose a sound first response.
