Petrophysics of Shales

13 December, 2012
Who Should Attend
Geologists, geophysicists, engineers and other explorationists who need a better understanding of the petrophysical aspects of shales and carbonates.

Course Content

The overall objective of this e-symposium is to review the petrophysics of shales and organic rich shale associated with carbonates. The course will review core data, petrophysical comparisons, rock physics modeling (including pseudo logs and mechanical properties).

Course Outline

  • Basic Petrophysics: What do these logs reveal about shales?
    • Porosity Logs
    • Resistivity Logs
    • Gamma Ray
    • SP
  • Interpretations – The Basics with a focus on shale
    • Shale calculations
    • Porosity calculations
    • Resistivity/Porosity cross plots to solve Archie’s equation
    • Influence of clays
    • Saturation determination
    • Permeability estimates
  • Core Data/Petrophysical comparisons
    • Porosity
    • Fluid saturations oil/water/gas
    • Grain density
    • Permeability
    • Core Shifting
    • Core upscaling – to match log measurements
  • Organic rich shale associated with carbonates
    • TOC
    • Shale petrophysical model
    • Free vs. adsorbed hydrocarbons
  • Rock physics modeling
    • Pseudo logs to verify porosity log integrity
    • Mechanical properties – brittle vs. ductile

Structure of the E-Symposium

Each e-symposium consists of one-hour live e-symposium, along with material for one full day of independent study. The live portion will be followed by a full day of independent study (not a live event). The one-hour live e-symposium can be accessed from any computer anywhere in the world using a high-speed internet connection. After the event is over, you will receive via email information about accessing the asynchronous segment (not live) which consists of your independent study materials, to be accessed and studied at any time. You will be able to email responses to the readings, along with your study question answers for CEU credit (if you sign up for the extended package).

Recording of original webinar, packet of independent study reading materials, PDF of original PowerPoint presentation by FTP download. (Original presentation date: December 13, 2012.) Some materials will also sent by e-mail.
