Open Hole and LWD Interpretation Principles and Applications (PPH33)

  • 19-23 August 20245 daysVienna, AustriaCourse Fee: 3750 EUR + VAT
    Computer Fee: 250 EUR + VAT


This interactive, applications-driven course will highlight the techniques and principles of well log interpretation for oil industry professionals who deal with wireline and/or LWD logs in their daily job.
The course will explore the tools response explained from their physical principles as well as their relationship with the rock and fluid properties; most existing open hole logging technologies will be covered explaining their main applications and limitations. Advanced interpretation methods will be discussed with numerous examples and exercises including complex lithology interpretation techniques.

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 advanced formation evaluation using wireline and LWD logs
  • Application of interpretation methods in several examples and exercises

Participants are welcome to bring their own laptops to class.

Course Level: Foundation / Skill
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 wireline and LWD 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 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.
