Reservoir Heterogeneity and Characterization

Projects, Facilities, and Construction


This course teaches field-scale reservoir characterization to evaluate heterogeneity and well-to-well communication. Class discussion will include standard measures of heterogeneity, such as the Dykstra-Parson coefficient, as well as newer methods to analyze interwell communication. Where possible, we confirm results against geological information.

Topics Include:

  • Statistical behavior of reservoir properties
  • Flow-storage (Lorenz) curves
  • Koval’s method of waterflood prediction
  • Permeability and percolation
  • Flow rate analysis to predict injector-producer communication

Learning Level


Course Length

1 Day

Why Attend?

Managing water floods involves determining which injectors are in communication with which producers. Communication is influenced by the heterogeneity, so that we can improve our understanding of the reservoir and which characteristics are controlling the well-to-well communications. Using the tools covered in this course, you will understand how communication can be measured and used for better management.

Who Should Attend

This course is designed for engineers with at least a bachelor’s degree in petroleum or chemical engineering and some exposure to geological concepts. All other engineers, geologists, mathematicians and physicists with at least some experience in reservoir engineering or numerical simulation can benefit from this course.


0.8 CEUs (Continuing Education Units) will be awarded for this 1-day course.


Jerry L. Jensen is a professor at the University of Calgary, teaching and researching reservoir characterization topics such as interwell communication, petrophysical analysis of tight oil reseroivrs, and geological statistics.

Jensen was a 2011-2012 SPE Distinguished Lecturer on the topic of evaluation interwell communications, and is co-author of two books on reservoir characterization. He holds a PhD in petroleum engineering from the University of Texas at Austin.

Larry W. Lake is a professor in the Department of Petroleum and Geosystems Engineering at The University of Texas at Austin, where he has taught since 1978 and served as department chairman from 1989 to 1997 and again from 2007 to 2009. Lake is a specialist in reservoir engineering and geochemistry. His work in quantifying the effects of geochemical interactions and flow variability for resource recovery is now widely applied by the industry. He has authored four textbooks and more than 100 technical articles and reports. He earned his BS and PhD from Arizona State University and Rice University, respectively. Lake has twice been designated as an SPE Distinguished Lecturer and member of the SPE Board of Directors.
