Description

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

The benefits from attending

• How to do Quick Log analysis quickly and efficiently with far greater accuracy and far greater confidence than before
• Doing your own Quick Look Analysis on your own laptop and save the entire process as a working template
• The essential operating principles, outputs and role of all conventional and special logging tools, their benefits and pitfalls, without getting bogged down in tool theory or irrelevant detail
• How to quickly identify porosity, saturation, netpay, fluid contacts, permeability and test intervals in a rapid, easy-to-understand workflow and become familiar with their typical log patterns
• Recognising your reservoir type and what you must do differently in each one
• Why and when to run ‘special logs’ including image logs, NMR, array sonics, rotary sidewall cores and MDTs
• How to avoid wasting time on secondary issues and to keep your mind focused on what really matters
• Acquiring the key data that moves the bottom line and to cancel the data that does not. This means making correct decisions real time which is only possible if your quick look is robust. After this course you will know if your results are robust.
• How to use PetroDB and other wells quantitatively during quick look to firm up your decisions
• Verifying your geo-models and field development log analysis with simple, effective techniques
• Presenting your results succinctly and with conviction because you know they have been cross-checked against hard data using established petrophysical principles
