Log Analysis of Shaly Sandstones

Learn the latest techniques of analyzing well logs for shaly sandstones! Don’t delay – Log Analysis of Shaly Sandstones is taught by George Asquith, a leading expert in the field, and will be offered in Houston on September 19, at the AAPG Fall Education Conference.

The course begins with a short review of the basic principles of well logging. Next are a series of lectures on the calculation of volume of clay/shale (Vcl), use the Vcl to correct the reservoir’s total porosity (total) to effective porosity (e). Then be able to apply a shaly sandstone producibility plot (Q-PLOT) to determine if the shaly sandstone is a reservoir. The next step is to determine using log data if the reservoir has effective or non-effective clay present and what shaly sandstone model can be used to convert total water saturation (Swtotal) to effective water saturation (Swe). Several models will be presented for determining Swe. A flow chart is provided that will aid the participants understanding the sequence that I use in analyzing sandstone and shaly sandstones. At conclusion ten examples will be presented that will be analyzed by the participants. The course will end with a case study of log analysis gas-bearing Woodford shale.

At the conclusion of the one day course the course participants should be able to do the following:

  • Scan a well log to determine zones that potentially could be hydrocarbon productive.
  • Be able to examine pre-processed and calculated well log data and be able to answer the following questions.
  • Is the sandstone a shaly sandstone?
  • Is the reservoir water-wet or oil-wet?
  • Is the reservoir potentially hydrocarbon productive?

Once the above four questions are answered the participants should be able to determine a strategy to improve the calculations of the reservoir’s effective porosity (e) and effective water saturation (Swe).
