Course Content

This e-symposium will be introducing signal processing techniques as a means to maximize extracting geomechanical data from petrophysical logs. The focus will be on different signal processing techniques that can be used to mine data from log data.

Well logs are key input data to construct and verify geomechanical models and unquestionably the most important data when it gets to rock property modeling. In addition, they usually show correlations, in some extent, with down-hole information such as fractured intervals, enlarged hole sections, oil/water/gas bearing zones etc. Although there are many petrophysical approaches to extract highest amount of information from logs, there is still a lot more valuable information buried in different frequency levels of log signals which cannot be pull out with the common petrophysical methods.

This presentation shares the results of an attempt to apply some helpful signal processing techniques such as wavelet de-composition, de-noising, Parzen classification, Bayesian algorithm, and data fusion to mine extra information out of log data.

In this study, the capability of signal processing techniques was examined for two main objectives: detecting borehole breakout intervals and identifying fractures zones. A new multi-variable workflow was proposed to identify zones of interest in correlation with basic well logs.

The workflow was applied to actual logs from a shale gas and a carbonate reservoir to investigate its accuracy and applicability. Results confirmed that the workflow is able to identify breakout and fractured zones with a significant accuracy.

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 24, 2013.) Some materials will also sent by e-mail.
