Integrated Petrophysics for Laminated and Low Resistivity Reservoirs
|Instructor Mark Deakin, PhD (Petrophysics)
Public courses 3 days. Tailored In-House
Shaly Sands, Laminates and Low Resistivity Low Contrast Pay reservoirs are and always been the primary problem with log analysis. This course separates and characterises these three overlapping Reservoir Types and sets out the data sets and petrophysical integration to best identify and evaluate each reservoir type; accurately. Like all the author’s ‘Integrated Petrophysics..’ courses this course steps through a logical process to identify cheap, powerful and commonly available data which is useful to the evaluation. It sets out the essential routine and contingent special logs and core data to arrive at fit-for-purpose results. Shaly Sands (SS), Laminates (LAM) and Low Resistivity Low Contrast (LRLC) pay reservoirs are defined, delineated and treated separately or together, as each petrophysical method demands. All modern logs including NMR, Dielectric, Spectral GR and Image logs are covered, together with established and novel core data integration techniques. Quick Look evaluation is included and demonstrated using real-time Interactive Petrophysics demos. Numerous Micro-practicals, videos and open discussion sessions keep this class a memorable learning experience!

Mark Deakin is a 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 25 years’ experience, including 18 as a course instructor with PetroSkills and HOT Engineering. He has performed over 60 detailed reservoir studies worldwide; primarily in Southeast Asia’s low-contrast pay and carbonate & fractured reservoirs. Deakin’s proven approach is to identify and rank reserves uncertainties then guide companies 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 the industry’s benchmark petrophysics training course. This was followed by courses in Carbonate & Fracture petrophysics and 3 day focused modules on How to use Modern Logs with SCAL, Quick Look Integration Techniques, Low Resisivity Low Contrast Pay, Laminates & Thin Beds, Using PetroDB effectively and Renewable Energy. The uniquely powerful PetroDB-WEB core-log-test linked database is his current project. Deakin is an active member of SPWLA and occasional lecturer at Curtin University and his consulting company PETROPHYSICS Pty Ltd has offices in Perth, Australia
