Course Description and Outline

This 8-hour course will give both geoscientists and engineers:

Session One Topics: Introduction

  • Logging measurements and acquisition of data
  • Data formats and sources
  • Depth control and uncertainties
  • Well surveys and well placement in Geo-space

Session Two Topics: Qualitative Log Analysis, Reading the rocks from well logs

  • The “triple-combo” measurement theory
  • Lithology vs. facies and what is shale?
  • Sensing grain size and depositional environments in clastics
  • Visualizing geochemical evidence in determining rock lithology
  • Visualizing the reservoir, fluid content and permeability

Session Three:  Breakout sessions.

  • Reading the logs: Break-out groups will be given a set of logs to discuss in group and report to the class. The analysis will include potential reservoir rock, lithology of the rock sequence, depositional evidence, wellbore quality, etc.
  • Well-to-well correlation: Participants will get a set of well-logs to correlate with focus on structure and depth control (The data sets will be paper plots or digital LAS files).
  • Well-to-well correlations using stratigraphic depth controls.

Lunch Break

Session Four: Quantitative Log analysis Litho-porosity models.

  • Techniques for clay and mudstone volume
  • Mixed lithology techniques such as graphical MMA and deterministic models
  • Total porosity versus “effective” porosity

Session Five: Resistivity and water saturation

  • Quantitative resistivity, what corrections are important? What are the quantitative parameters?
  • Archie Equation, Pickett Plots and the relationship to core analysis
  • Advanced saturation equations (e.g., Simandoux): how do we determine parameters?
  • Evidence and measurements of hydrocarbon types.
  • Economic parameters from the analysis

Session Six: Break-out session

  • Participants will get a shale/sand well to process for economics evaluation.  The data sets will be paper log plots and graphing papers, or digital from .LAS files.

Wrap-up discussion for the day one.



The aim of the short course is to create a learning environment that can educate the novice and challenge the experts.  There will be several in-class exercises and break-out discussions to get hands-on experiences. Course materials will be available to work on paper or digital files to process on the computer, participants that use a petrophysics platform are encouraged to bring a Laptop.  Other course materials provided will be a list of references and a 3 month license of Hydrocarbon Data Systems Petrophysical platform HDS-LOG.
