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.
Course Level: Skill
Duration: 5 days
Instructor: Mark Deakin
Designed for you, if you are...
- A petrophysicist, geologist of any discipline, reservoir engineer, geophysicist, core analyst or someone with a year’s experience with logs or formation evaluation
How we build your confidence
- This course is a condensed package of powerful integration techniques. It uses an interleaved sequence of lectures, micro-practicals, interactive Petrophysics & Geolog demos, movies and workshops to convey a flexible and very powerful petrophysical methodology. Its comprehensive manual and petrophysical toolbox provide a lasting benefit to the novice and experienced student alike.
- Basic economics are addressed first by Quick Look log analysis for operations and then by a disciplined, logical process to optimize the interpretation of Porosity, Saturation, Permeability and Fluid Contacts – the basis of reserves.
- Low contrast low resistivity pay, clastics and carbonates are evaluated by straight forward integration techniques which outperform log analysis with direct, plain to see results.
- The integration of LWD, wireline, facies, SCAL, MDTs etc is explained via the author’s ‘PetroDB-Vault’ software with the final, crucial Petrophysics-Geomodel checks clearly set out.
