This interactive, applications-driven 5-day GLOMACS Open and Cased Hole Log Interpretation training course will highlight the techniques and principles of the main open and cased hole logging tools used in the oil industry for professionals who needs to deal with wireline logs in their daily job.

This GLOMACS training course will explore the tools response explained from their physical principles as well as their relationship with the rock and fluid properties, most common open and cased hole logging technologies will be covered explaining their main applications and limitations. Interpretation methods will be discussed with examples and exercises.

This GLOMACS training course will feature:

• Discussions on open hole tools physical principles and applications
• Tool limitations on different borehole environments
• Tips and examples to identify and understand common logging issues
• Explanation of petrophysical concepts and techniques for basic log interpretation
• Cement and corrosion evaluation tools principles and applications
• Cased hole resistivity, porosity and saturation tools
• Application of interpretation methods in some examples and exercises

By the end of this GLOMACS training course, participants will be able to:

• Understand the physical principles of main open and cased hole logging tools
• Know the main applications and limitations of the different tool readings
• Perform a quantitative formation evaluation on a simple lithology
• Understand the uses and interpretation of open and cased hole logging tools

This GLOMACS Open and Cased Hole Log Interpretation training course will utilise a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented, the sessions will include visual, auditory and kinesthetic elements to cover the three different learning modalities. The daily sessions will be highly interactive and participative. This involves regular discussion of applications as well as hands-on exercises that will be solved manually and/or using Microsoft Excel.

The organization will benefit because:

• Having their personnel trained on log interpretation will help reduce human mistakes and improve efficiency
• The cement evaluation training provided will enable the participants to properly interpret cement bond logs allowing for more informed decisions on casing and well integrity issues
• Their personnel will be able to better assess data quality and integrity
• Their personnel motivation will increase as they understand better some critical data that is needed for their daily job

Attendees will gain by participation in this GLOMACS training seminar as a result of:

• Obtaining a full understanding of logging tools principles and applications
• Learning the principles and key indicators for log quality assurance and quality control
• Learning basic and advanced methods and techniques for log interpretation
• Getting awareness of the safety policies involved on operations with explosives

This GLOMACS training course is suitable to a wide range of professionals but will greatly benefit:

• Engineers in exploration and production departments
• Geologists, Geophysicist and Petrophysicist
• Petroleum, Reservoir and Drilling Engineers
• In general, all other oil & gas industry professionals who are involved in logging data interpretation and validation
