Reservoir Fluid Properties: Preparation for Reservoir Engineering and Simulation Studies - RFP

May 23, 2014

This course goes beyond the usual description of reservoir fluid properties. The underlying purpose is to be able to prepare the most accurate possible set of values of fluid properties for use in other engineering calculations. An understanding of the advantages of the application of both laboratory data and correlations will be provided. Exercises that utilize actual field and laboratory data are used to illustrate the principles and to ensure understanding of the applications of the procedures. The course also introduces the participants to the evolution of modern computational capabilities that allow engineers to use EOS models to study phenomena such as the development of miscibility during gas injection, compositional gradient and the behavior of near-critical hydrocarbon systems. The participants are encouraged to bring their own PVT laboratory date to discuss in class. One personal computer is provided, at additional cost, for each two participants.

Reservoir, production and facilities engineers who have a need to determine values of reservoir fluid properties and use Equations of State for engineering studies and reservoir simulation

You will Learn:

Participants will learn how to:

  • Identify the type of fluid in a particular reservoir and in general how that fluid will behave during production
  • Use laboratory data to determine values of fluid properties for use in engineering calculations
  • Use correlations to determine values of fluid properties in the absence of laboratory data
  • Select the best available fluid property correlations for oils, gases, and oilfield waters
  • Apply Equations of State and tune EOS to match experimental PVT data
  • Shape PVT data to get the best results out of analytical and numerical software.
