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 replaces the need to run expensive, irrelevant logs, explain apparent data conflicts and provides the correct answer faster, strengthening your position as an operator and petrophysicst. By contrast, stand-alone log analysis often results in wrong decisions and weakens your position in the eyes of your line-manager and business partners. This course, evolved over 25 years of petrophysical consulting and training, demonstrates how robust answers are achieved by the logical integration of diverse data. Pay and reserves are addressed first by Quick Look Log Analysis and then by a disciplined, logical process to optimize the interpretation of Porosity, Saturation, Permeability and Fluid Contacts – the basis of Reserves. Low Contrast Pay, clastics and carbonates are evaluated by straight forward integration techniques which outperform log analysis with direct, plain to see results. The integration of Mudlogs, LWD, Wireline, Facies, Rock Types, SCAL, NMR, Dielectric, MDTs etc is explained via the author’s 28,000 core plug PetroDB-WEB software.  Finally, those crucial Petrophysics to Geomodel checks are clearly set out.

This course is a condensed package of powerful integration techniques. It uses an interleaved sequence of lectures, micro-practicals, IP & Geolog demos, movies and workshops to convey a flexible and very powerful petrophysical method. It’s manual provides a comprehensive and lasting benefit to the novice and experienced student alike. This course was the first public petrophysics integration course (Jan1990) and remains The Benchmark Petrophysics Course today. Do not be fooled by imitations!

Instructor CV

Dr Mark Deakin is a consultant, author and lecturer in Petrophysical Data Integration. He holds a Ph.D. in ‘Integrated Petrophysics’ from London’s Imperial College, is an ex Amoco petrophysicist, and has more than 30 years’ experience, including 15 as a lecturer and director of PETROPHYSICS Pty Ltd. He has performed over 50 detailed reservoir studies, primarily in Southeast Asia’s difficult carbonate and stacked ‘low-contrast-pay’ reservoirs, keeping abreast of new technologies by technical reading, operations work, attending short courses and lecturing. Mark’s proven approach is to identify and rank reserves uncertainties, then guide companies toward defensible reserves via a process of targeted data acquisition, data-hierarchy and systematic integration. After his Ph.D. Mark authored the first public Integrated Petrophysics course which has evolved into the industry benchmark course for mainstream petrophysics.  Deakin also developed “Integrated Petrophysics for Carbonate & Fractured Reservoirs – A Roadmap”  and the powerful PetroDB-WEB core-log-test linked database evaluation for complex reservoirs. Deakin is a member of SPWLA with offices in Perth, Australia.
