Description

• 3 modules of 4 hours each, delivered over 3 days
• Optional: Pre-course self-learning module
• Optional: Post-course self learning module incl. Q&A opportunity

Designed for you, if you are...

• An operations or wellsite geologist or petrophysicist
• An experienced log analyst, user of petrophysical results or geo-modeller
• An exploration manager or team leader
• A professional who could benefit from being aware of the numerous quick and easy but never used techniques that transform quick look log analysis into robust, hard edged results

How we build your confidence

• This course uses a wide variety of delivery mechanisms which build a clear understanding and template for all quick look petrophysical evaluations.
• This course provides fast and effective tools for the real time drilling environment. The process provides simple log specific check boxes for the stressed petrophysicist working under the rule of the bit. It also provides an easy to apply tool for geologists and engineers to independently check their existing geo models before making major decisions - opening the petrophysical black box to the team.

• Pre is designed to focus and prepare you for the main VILT session
• Post allows you to practise and quiz yourselves and the instructor before closing out the course

The benefits from attending

• Keep your mind focused on what really matters
• Know how to make the correct decisions faster, real- time with robust, cross-checked quick look results (…and after this course your Quick Look will be robust!)
