This interactive, applications-driven course will highlight the techniques and principles of formation evaluation for oil industry professionals who deal with wireline and/or LWD logs in their job.
The course will explore the tools response to different lithologies and will help you understand log readings, applications and limitations. It will instruct you with the basic Petrophysical concepts as well as the log interpretation techniques and procedures for the correct evaluation of well logs on clean and shaly sand formations. This training course 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
Course Structure: 4 modules of max. 4 hours each, delivered over 4 days Each day will consist of 1 module which will be no more than 4 hours in length with ample time for delegates to break for refreshments.
Course Level: Foundation / Skill Duration: 4 days Instructor: Angel Meso
Designed for you, if you are...
An engineer in the exploration and/or production department
A geologist, geophysicist or petrophysicist
A petroleum, reservoir or drilling engineer
In general, any oil & gas industry professional involved in logging data interpretation and validation
How we build your confidence
This 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 be given in real time through live webinars (instructor-led training); some exercises will be executed during the sessions, others will be done as homework.
The daily sessions will be highly interactive and participative. This involves regular discussions of applications as well as hands-on exercises that will be solved manually and/or using Microsoft Excel.
