Overview

Public course 3 days. In-House courses can be tailored as 4 or 5 day courses or amalgamated with IPSWHT, IPLAM or IPSCAL into a single 5 day course.

This 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 on IP following established petrophysical principles but within an operations ‘quick look’ setting. The quick look evaluation is demonstrated step by step with the addition of the authors multi-disciplinary techniques which cross check and verify each step to flag and arrest the propogation of error. This provides for robust, fact-based decisions during operations. Log analysis field studies can also be quickly and efficiently checked by these simple techniques.

Tools are introduced as they arise in quick look to emphasise their contribution to the logical flow of information. The diversity of inputs used affords a degree of confidence simply not possible with conventional quick look log analysis moving you into an environment of certainty, confidence and leadership which benefits everyone downstream of the drill bit.

Turns your quick look Log Analysis into Evidence Based Petrophysics

Course Level: Foundation

Who Should Attend?

Operations Geologists, Petrophysicists, Wellsite Geologists, Experienced Log Analysts, Users of petrophysical results, Geo-modellers, Exploration Managers, Team Leaders. Anyone who could benefit from being aware of the numerous quick, easy but never used techniques that transform quick look log analysis into robust, hard edged results.

Bring your laptop with MS Excel.

What You Will Learn

To do Quick Log Analysis quickly and efficiently with far greater accuracy and far greater confidence than before
To do your own Quick Look Analysis on your own laptop and save the entire process as a working tliplate
To quickly understand 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 details
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
To recognise your Reservoir Type and what you must do differently for each during operations
To understand why and when to run ‘special logs’ including Image logs, NMR, Array sonics, Dielectric, Rotary sidewall cores and MDTs
To avoid wasting time on secondary issues and to keep your mind focused on the results which really matter
To acquire 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 your Quick Look will be robust!
To use PetroDB, other wells and special logs quantitatively during quick look to firm up your decisions
To verify your geo-models and field development log analysis with simple, efficient techniques
To present your results confidently and with conviction because you know that, unlike other evaluations, yours have been properly cross checked against hard data using the established principles set out in this course.

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.

Instructor CV

Mark Deakin is a technical consultant, author and course instructor in Petrophysical Data Integration. He holds a Ph.D. in ‘Integrated Petrophysics’ from London’s Imperial College, is an ex Amoco petrophysicist and has over 30 years’ experience including as a course instructor with PetroSkills and HOT Engineering. He has performed over 70 detailed reservoir studies worldwide; primarily in Southeast Asia’s low-contrast pay and carbonate reservoirs. Deakin’s proven approach is to identify and rank reserves uncertainties for operators and investors, then guide operators towards defensible booked reserves via the application of new technology, targeted data acquisition and the systematic, logical integration of all related data. After his PhD Deakin authored the first public Integrated Petrophysics course in 1989 which evolved into IPRC, the industry’s benchmark petrophysics training course. This was followed by courses on Carbonate & Fracture Petrophysics IPCFR and focused modules on Quick Look Techniques IPQL, Using Modern Logs with SCAL IPSCAL, Low Resistivity Pay IPLAM, Saturation Height IPSWHT, Using PetroDB Effectively IPPetroDB and Renewable Energy REP.

Deakin’s core interest is the integration of diverse technologies to solve problems. Integration of the uniquely powerful PetroDB, cross-linked core-log-test database, with mainstream software is his current project. Deakin is an active member of SPWLA and occasional lecturer at Edit Cowan & Curtin University. His consulting company PETROPHYSICS Pty Ltd has offices in Perth, Australia and he has homes in Perth and London.
