Integrated Petrophysics - Quick Look Techniques (PPH06)
23-25 November 2020 3 days London, United KingdomCourse Fee: 2750 EUR + VAT
Computer Fee: 150 EUR + VAT
Description
This course walks through how to perform a Quick Look Log Analysis which is integrated with commonly available non-log and special log data. The process is easy to understand and performed real-time, following established petrophysical principles but within an operation's 'quick look' setting.
The course uses simple multi-disciplinary techniques to quickly cross check and verify petrophysical results on the fly to enable more objective, fact based operational decisions. Log based field development studies can also be checked and verified by these quick look techniques.
Verifying petrophysical results moves you into an environment of certainty, confidence and leadership. These petrophysical techniques will benefit everyone downstream of the drill bit.
Course Duration: 3 days
Course Level: Foundation

Designed for you, if you are...
- Keen to learn the numerous quick and easy - but never used - techniques that transform quick look log analysis into robust, hard edged results
The course is aimed at operations geologists, petrophysicists, wellsite geologists, experienced log analysts, users of petrophysical results, geo-modellers, exploration managers, team leaders,...
How we build your confidence
Daily recaps, questions and debate. These debates will revolutionise the way you think about and perform quick look log analysis.This course is not difficult; it is common-sense but will surprise the experienced log analyst who has never used the numerous simple, easy to apply techniques which transform quick look log analysis into fact based petrophysics. These techniques eclipse sophisticated, black box log analysis and are mostly completely free to use. If resources are to be spent on push button log processing or running special logs it is advisable to at least be aware of these simple checks.
The benefits from attending
By the end of the course you will feel confident in your understanding of:- 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
