Basic Formation Evaluation

Introduction

This interactive, applications-driven 5-days LAKESHORE ISL Basic Formation Evaluation training seminar will highlight the techniques and principles of formation evaluation for oil industry professionals who needs to deal with wireline and/or LWD logs in their job environment.

This LAKESHORE ISL Basic Formation Evaluation training seminar will explore the tools response to different lithologies and will help participants understand log readings, applications and limitations. It will instruct them with the basic Petro physical concepts as well as the log interpretation techniques and procedures for the correct evaluation of well logs on clean and shaly sand formations.

This LAKESHORE ISL training seminar will feature:

• Discussions on 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 formation evaluation
• Application of interpretation methods in several examples and exercises

Objectives

By the end of this LAKESHORE ISL training seminar, participants will be able to:

• Understand the physical principles of main logging tools
• Apply basic quality control techniques to validate logging data
• Know the main applications and limitations of the different readings
• Perform a quick qualitative interpretation to determine possible interest zones
• Perform a complete formation evaluation on a shaly sand environment

Training Methodology

This LAKESHORE ISL Basic Formation Evaluation training seminar 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.
