IPLAM Integrated Petrophysics for Laminated and Low Resistivity Reservoirs – Clastics & Carbonates

Mark Deakin, PhD

This course details ten techniques which radically improve shaly sand and low resistivity petrophysical evaluation in clastics and carbonates. Laminates, Low Resistivity Low Contrast Pay (LRLC), Shaly Sands, Bi-modal microporous and conductive mineral reservoirs are characterized, diagnosed and treated sequentially and accurately.

The course steps through a logical process to find commonly available powerful data to address the problem and then sets out the optimal evaluation path to achieve robust results for each reservoir type. All modern logs including XYZ Resistivity, NMR, Dielectric, Pulsar, LithoSpectral GR, Sigma and Image logs are covered, together with numerous core-log and log-log cross-calibration techniques.

The course includes the rigorous application of XYZ resistivities with Thomas Stieber and Qv as well as a Quick Look Shaly Sand evaluation of a routine logging run using a real-time Interactive Petrophysics template, with equations. This template can be reused for future wells with IP or other software (See PetroDB). Micro-practicals, videos and open discussion keeps this class an eye-opening and memorable learning experience, especially for those who have evaluated LRLC pay, who are encouraged to share their experiences.

Petrophysics Course Instructor & Technical Consultant

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 30 years’ experience, including 25 years as a course instructor. He has performed over 60 detailed reservoir studies worldwide; primarily in Southeast Asia’s low-contrast pay and carbonate & fractured reservoirs. Deakin’s approach is to identify and rank reserves uncertainties then guide companies towards defensible reserves and optimal development 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 three day focused modules on Quick Look Integration Techniques; How to use Modern Logs with SCAL; Low Resisivity Low Contrast Pay; Laminates & Thin Beds; How to use PetroDB effectively and a Renewable Energy.

Deakin's special interest has been using PetroDB (a generic, rock typed petrophysical database) and SCAL Digital Rock Physics with logs to identify Missed Pay and EOR. Since 2010 he has been drawn to the inevitability of Renewable Energy, writing the course Renewable Energy Primer in 2015. He is an active member of SPWLA and occasional lecturer at Curtin University and his consulting company PETROPHYSICS Pty Ltd has offices in Perth, Australia.
