Petroleum Reservoir Fluid and Phase Behavior


This course aims to teach participants the fundamentals of hydrocarbon properties, along with their phase behaviors and practical applications in the production systems.  Participants will learn about the technical fundamentals and property correlations, as well as how to apply phase behavior and thermodynamics in order to solve real life problems.  

Specific topics that will be covered during this course will include the components of petroleum, the construction of phase envelopes, the plus fraction concept, and the classification and identification of fluid types. The calculation of the viscosities of each fluid type, interfacial and surface tension, lab and field tests, and a simulation of transport properties of petroleum fluids will also be discussed.

The objectives:

  • To understand the petroleum reservoir fluids and phase behavior.
  • To identify components of petroleum
  • To create phase envelopes,
  • To be able to classify and identify of fluid types
  • To determine properties of crude oil and the formation water. 
  • To learn about natural gas fundamentals and classification, behavior of ideal gases, behavior of real gases, and the effect of the water content in the properties of natural gas. 
  • To learn about the transportation properties of petroleum, gas, water, and emulsions.
  • To learn material balances, applications of equilibrium ratios, determining dew point and bubble point, and other equilibrium.
