PETROPHYSICAL LOG ANALYSIS


COURSE AND WORKSHOP

December 5 - 9, 2010

Instructor : JOHN DOVETON, Ph.D.


WHO SHOULD ATTEND

Petrophsicists, geologists, geophysicists engineers, or anyone interested in a solid understanding of principles of borehole geophysics.

COURSE OBJECTIVES

General principles of physics are developed to explain the behavior of modern logging tools. A feature of this course is the large number of actual log examples used to illustrate and describe reservoir properties. Participants gain realistic experience by working in teams on comprehensive log interpretation exercises.

Participants will learn how to:

  • dentify reservoirs.
  • Determine mineralogy, porosity and saturation in various.
  • Highlight oil mobility.
  • Interpret pressure profiles.
  • Develop optimum tools and logging programs.
  • Apply quick look methods of formation evaluation.

  • General principles of physics as applied to modern logging tools
  • Reservoir/non-reservoir discrimination, matrix sensitive logs
  • Formation resistivity factor, Effects of shales
  • Deep - and Shallow-reading Resistivity measurements
  • Porosity-mineralogy logs (Density, Neutron, and Sonic)
  • Porosity determination in clean formations, borehole calipers
  • Improved Mineralogy identification using newer log measurements, Sidewall coring
  • Saturation and Archie equation, porosity-resistivity crosses plots
  • Quick-look methods for preliminary determination of mineralogy, fluid saturation
  • Nuclear magnetic resonance measurements
  • Overview of permeability measurements
  • Overview of computer-aided interpretation
  • Log Quality Control

INSTRUCTOR PROFILE

John H. Doveton received his MA degree from Oxford and PhD from Edinburgh University, both in geology. Following work as an exploration geologist for Mobil Oil Canada, he joined the Kansas Geological Survey where he is a Senior Scientific Fellow, and Professor in Geology and Petroleum Engineering at the University of Kansas. He has taught log analysis courses for universities and industry in the United States, Canada, Europe, the Middle East , India, Mexico, Venezuela, Brazil, Australia, and Indonesia since 1975, and is an author of widely-used interactive computer log analysis systems. He received the 1981 Best Paper Award from "The Log Analyst" and has been a Distinguished Speaker for the SPWLA as well as receiving the IAMG Griffiths Award for Excellence in Teaching in 1998. He is the author of the textbooks, "Log Analysis of Subsurface Geology" (Wiley-Interscience, 1986), "Geologic Log Interpretation" (SEPM, 1994, 2004), and Geological Log Analysis Using Computer Methods (AAPG, 1994).
