DESIGNED FOR

Petrophysicists, petroleum reservoir engineers, geologists and geophysicists who have a basic understanding of petrophysics, geology and engineering and need a more advanced understanding of how to integrate the different data sets together to more completely understand reservoir performance.

The participants should have a basic knowledge of well logs evaluation.

YOU WILL LEARN HOW TO

• Identify clastic and carbonate rock types based on productivity differences

• Determine the key reservoir rock parameters needed for a more accurate reservoir evaluation

• Learn how to use cuttings, sidewall cores and cores to determine reservoir parameters

• Design an integrated interpretation

• Calculate Vclay

• Calculate porosity using porosity logs in complex lithologies.

• Determine what percentage of porosity contributes to production

• Calculate Sw using different methods

• Determine pay and pay classes

• Tie rock and well log information to production performance

ABOUT THE COURSE

This course provides the background necessary to solve complex reservoir evaluation and productivity problems faced in Exploration, Field Appraisal and Field Development. The key fundamentals of rock properties, logging tools and engineering data needed to solve these problems are reviewed. The concepts are illustrated with a series of real world problems that become increasingly complex as knowledge is gained in the class. Emphasis is placed on solving problems in a workshop format.
