The course walks you through how to perform a Quick Look Log Analysis integrated with common non-log and special log data. The process is easy to understand and performed real-time following established petrophysical principles but within an operations ‘quick look’ setting. The course uses simple, multi-disciplinary techniques to quickly cross check and verify petrophysical results on-the-fly for more objective, fact based operational decisions. Existing log-based field development studies can also be checked and verified by these quick look techniques. The diversity of inputs used affords a degree of confidence simply not possible with conventional quick look log analysis and moves you into an environment of certainty, confidence and leadership which benefits everyone downstream of the drill bit.
Course Level: Foundation Duration: 3 days Instructor: Mark Deakin
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.
This course consists of five components to expand and maximise the course content delivery. The course content is varied and stimulating and includes short focused instructor videos; course notes extracts; micro-practicals, cornerstone 4 hour daily VILT sessions; before and after self-learning modules; Question & Answer sessions; industry videos & exercises; comprehensive Petrophysical Toolbox; Petro DB extracts; HPV sensitivities; How to demos; Quizzes & Answers
Before and After Self-Learning Modules These modules are an important extra component of the course:
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
By the end of the course you will:
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!)
