Introduction to Log Interpretation and Quality / Instructor Gary Batcheller
(PTRT2005)

DAILY SCHEDULE

DAY 1: Introduction to Log Parameters, Resistivity, SP, Gamma Ray and Porosity

Objective: by the end of this training day trainees will be able to:

• Understand basic logs and permeability concepts
• Read Resistivity logs and determine permeability indications
• Use the gamma ray and sp log to determine "potential" reservoir rocks
• Use Micro Resistivity logs to indicate permeability
• Understand how "Porosity" logs determine porosity
• Use Photoelectric log to help determine lithology

DAY 2: Topic: Determining porosity, gas effect, and lithology from logs and calculating water saturation.

Objective: by the end of this training day trainees will be able to:

• Determine porosity from Density, Neutron and Sonic logs
• Use Neutron and Density and photoelectric logs to determine lithology
• Use Neutron and Density logs to determine gas effect on logs
• Correct porosity calculations for gas
• Find potential pay zones from logs
• Calculate water saturation using Archie equation

NOTE:  Day 3 has been updated to include an introduction to the evaluation of rocks with organically rich materials and with extremely low permeability. These potential reservoirs are sometimes referred to as a resource rock or "shales". This section includes a discussion of geochemical logs and information from cores/log for Total Organic Carbon (TOC).

Since the success of fracture treatments are a significant part of the overall production for these reservoirs a section has been included on introduction to rock mechanics for both vertical and horizontal wells. In addition, current completion techniques for fracturing horizontal wells will be discussed.

DAY 3: Topic: Methods used to recognize a quality log and Logging Tool Limitations

Objective: by the end of this training day trainees will be able to:

• Use several methods to assist in evaluating log quality
• Have a better understanding of depth control and its importance
• Understand the environmental effects upon logs
• Determine which log will work best in which environment
• What can a tool be expected to do or not to do
• Review computer aided "quality" logs to help determine log quality

Gary Batcheller has over 35 years of experience in field operations and training in the petroleum industry. He has developed and presented training courses world-wide to over 2,500 students. He has taught classes on formation evaluation, the application to fracture stimulation and cement integrity as well as applied this information with consulting to operators, national oil companies and service companies. He has received a BS degree in Physics from Texas Technological University, and is a member of SPE, API and SPWLA. He has published several papers and received a distinguished service award in the area of formation evaluation.
