E – 1884 Heavy Oil Pumping


This course is presented by a program manager for a viscous (or heavy) oil pumping system (VOPS).  An overview of the concepts of pumping heavy oil with focus on use of water lubrication.   Adequate amounts of water are injected into the heavy oil flow to create an annulus or ring that forms around the heavy oil.  The annulus delivers a small amount of water at high pressure into the oil stream. This creates a water ring that contacts the pipe or hose wall thereby reducing friction compared to pumping oil only.  The reduction in friction causes less of a pressure drop or loss.   This type of oil pumping application is called core annular flow (CAF) since the lubrication water forms an annulus or ring around the oil core.

This course will provide an overview of the governing equations of core annular flow’s behavior.  Pressure drop and stability of the core annular flow stability will be addressed.   Because of the complexity of two liquids (water and oil) flowing together, core annular flow systems are designed typically using both quantitative and experimental methods.   Core annular flow systems represent an extraordinarily complex field dependent on advanced numerical methods, computer aided design, and results from field experiments.   A synopsis is provided of core annual flow research such as numerical analysis and experimentation results on minimum oil flow velocity and Reynolds number.

This is not an advanced fluid mechanics course.  It is presented so that an engineer with a limited fluid mechanics background can understand it.  There will be some quantitative explanations and a larger amount of qualitative description.  However, there will be more practical emphasis on the configuration and operation of a heavy oil pumping system.  The primary focus will be on the United States Navy’s viscous oil pumping system (VOPS) as a real-world example or application.     This includes a discussion of the configuration and performance of viscous oil pumping system’s positive displacement screw pump.
