We are currently offering two classes: 

1) Petrophysical multimineral analysis



Patricia Rodrigues


This course explains the basic concepts, assumptions, calibration, and implementation steps

needed to obtain reliable results when performing petrophysical multimineral analysis. This

training uncovers the mysteries of the multimineral solution. It is centered on explaining the

basic concepts, understanding the mathematical uncertainties, and exploring the

implementation of the technique to ensure not only a good mathematical solution but also a

reasonable, useful geological one. This is not a software training class; it is a conceptual class.

Although we utilize the iMineralysis® software to explore concepts, attendees will not emerge

from the class as users of any specific software. Exercises are based on iMineralysis® which

will be licensed to participants at no cost for the duration of the class.

Knowledge of basic logs and petrophysical concepts is highly recommended.

2) Construction of fractured reservoir models for flow simulation incorporating geology, geophysics and geomechanics 



Reinaldo Michelena (geophysics)

Chris Zahm (geology)

James Gilman (reservoir engineering)


This course examines datasets from both conventional and unconventional systems and present workflows to construct naturally-fractured reservoir models. Particular attention will be given to the use and calibration of a variety of 3D seismic attributes which are critical to our characterization efforts. The combination of 3D seismic data with sound stratigraphic and structural frameworks provides a more robust fractured reservoir model. Models and concepts are examined in the context of how they impact fluid flow, reservoir simulation results, field production, and forecast.


This 2-day course will present the workflows that have been developed along with spreadsheet-based exercises to solidify concepts. The workshop provides in-depth presentations and discussions of the models presented. Click here for more details about the 2-days course. A 1-day version of the course is also offered.

This class is designed to provide concepts and workflows for geoscientists and reservoir engineers that are constructing reservoir models of naturally fractured conventional and unconventional reservoirs. The breadth of subject matter is wide but is designed to be applicable to all disciplines regardless of years of experience.  This class is ideally suited for integrated teams working on naturally fractured reservoir characterization models.
