This two-day course is designed to provide the practical working knowledge needed by geotechnical support staff who work with geologists, geophysicists, and petroleum engineers. It provides an introduction to well logs, maps, cross sections, and geological data bases. exercises include:

  • Preparation of maps and cross sections
  • Concepts of structural and isopach contours
  • Correlation of logs
  • Measured depth and true vertical depth
  • Reading key information from log headers and log scales.
  • Students will become familiar with the types of well logs and how these logs are read and used.

The course also deals with practical realities of computer databases and computer-generated maps, including LAS files, how computers generate contours, recognizing and correcting problems with computer-generated maps, finding and correcting errors in databases, protecting databases and avoiding problems.


Two days


We believe this program meets the criteria for continuing professional development in many state and national professional organizations.


Exploration and production support staff, including geotechs, engineering techs, technical clerks, and new hires. No background in science or mathematics is required and the technical material is presented so that it will be easily understood by people without any prior training in geology or engineering.


  • Students in this course will learn
  • What the geologist or petroleum engineer needs to learn from well logs
  • Basic reservoir properties: porosity, permeability, formation fluids, properties that make a good petroleum reservoir, gas production from shale
  • Different types of logs and the measurements they make: Gamma Ray, Resistivity, SP, Porosity
  • Vertical and horizontal wells
  • Geological maps and cross sections
  • Normal and reverse faults
  • To calculate water saturation and petroleum reserves using logs
  • Spotting well locations
  • LAS files
  • Basic computer mapping
  • Practical management of computer databases

Special Features

Participants will receive printed lecture notes with diagrams, illustrations, and samples of electric logs. The course also includes practical exercises and hands-on experience.

(Laptop computers are suggested for hands-on exercises in class.)
