Recognizing Unconventional Pay from Wireline Logs

06 October, 2011
Who Should Attend
Geologists, Engineers, Geophysicists, and any Geoscientist, of all experience levels - anyone having occasion to review log data for potential bypassed pay zones and unconventional resources.

By participating in this e-symposium, attendees will be better equipped to:

  • Identify possible bypassed pay from logs in a variety of sediments.
  • Understand the mechanisms causing low resistivity and low contrast pay zones.
  • Understand the effects of clay, shale and laminations on log response and understand the potential effects of each on reservoir performance.
  • Understand typical log response of shale reservoirs.
  • Understand the impact of bed resolution of logs.
  • Understand the effects of natural fractures on log response and on reservoir performance.
  • Perform basic quality control of processed logs.
  • Understand basic considerations of shale gas and shale oil log analysis.
  • Recognize situations where additional logs, core, or other information might be needed for proper formation evaluation.
  • Have improved skills in recognizing unusual log signatures that can indicate an unconventional or bypassed resource
Course Content

The e-symposium contains several case studies and log examples of bypassed pay and unconventional resources including Niobrara, Bakken, Marcellus, offshore GOM and others examples including processed log quality issues. Basic principles of log response in bypassed and low contrast pay / unconventional resources and processed log quality will be presented to the class. The e-symposium is focused on pattern recognition and quicklook techniques, and using different techniques for recognizing unconventional pay from wireline logs.

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: October 6, 2011.) Some materials will also sent by e-mail.
