Integrated Petrophysics for Reservoir Characterisation

Course review:

This course will teach you how to evaluate reservoirs and quickly identify flawed results.
Robust reserves and simulation are achieved by the logical, systematic integration of all relevant data. A quality interpretation is extremely cost-effective compared with data acquisition or development mistakes and essential with today’s complex reservoirs and data sets.
Integration will often replace the need to run expensive, irrelevant logs, explain apparent data conflicts and provide the correct answer faster, strengthening your position as an operator. By contrast, stand-alone log analysis often results in wrong decisions and weakens your technical position in the eyes of your partners.

This course, evolved over 25 years of petrophysical consulting and lectures, demonstrates how robust answers are achieved by the logical integration of diverse data. Integrated Petrophysics was the first public petrophysics integration course (Jan1990) and remains the Benchmark Petrophysics Course today.


THE BENEFITS FROM ATTENDING:
By the end of the course you will feel confident in your understanding of:

• The essential nature of petrophysics: its objectives, data and uncertainties
• How to get the best possible answers from any given data set
• How to perform Quick Look Log Analysis and Essential Core-Log Integration with the author’s Excel spreadsheets
• How to review petrophysical studies effectively & quickly identify flawed results using a clear sequence of logical checks
• How to identify and extract the key data channels from modern hi-tech logs which, when integrated with core, logs and welltests, will answer the questions your team is asking
• What really matters from the increasingly complex barrage of modern petrophysical data
• How to drill, core, log and test for clear formation evaluation results
• How to avoid the 10 most common errors which ruin petrophysical results
• How to use interactive software to reveal how your data works together and impacts results
