Course Objectives

To get acquainted with different well logging tools and their use in determining reservoir petrophysical properties including porosity, water saturation, and even permeability. Trainees will learn how to read and interpret different well logging plots, equations, as well as charts (Histogram and Cross-plots). They will also practice how to process raw well logging data to meaningful presentations using well log plots, histograms, and cross-plots using a commercial software.

Course Description

This course provides an introduction to the various well logging methods, tools and their principles of operation with emphasis on the relationship between measurements and reservoir petrophysical properties. Conditions and limitations for applications of various logs are discussed. Graphical and analytical methods used to determine formation composition, contents, and its potential for production are developed and applied to create graphs and log traces, and determine reservoir parameters.

Learning Outcomes

Upon completion of the course, participants will learn the following:

Know the different well logging tools and measurements
Identify the relations of electrical resistivity, radioactive, and acoustic properties of rocks
Compare well logging data for different reservoir conditions
Evaluate the effects of measurement environment on logging data
Assess reservoir properties using different logging data
Understand calibration and correction of different well logging tools
Processing of raw well logging data to meaningful representations of well log plots, histograms, and cross-plots


The course will be delivered in the form of lectures using PowerPoint. Lecture materials will be given to trainees.

Method of Delivery & Teaching/Learning Approaches

This is an online course that includes hands-on practice/calculations during the solving sessions. A pre-exam as well as a post-exam will be given to the trainees to evaluate how much they gained out of this short course. The exam will be in the form of multiple choices questions for about 30 mins.

Who Should Attend

Petroleum engineers, exploration engineers, production engineers, geophysicists, petrophysicists or other technical personnel with at least a BSc degree and some experience in well logging. The course benefits both new recruits as well as experienced professionals with interest in well logging data interpretation and validation.
