Overview
Public course 3 days. In-House courses can be tailored as 4 or 5 day courses or amalgamated with IPSWHT or IPSCAL into a single 5 day course.
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.

Course Content
Instructor CV
Mark Deakin is a technical 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 as a course instructor with PetroSkills and HOT Engineering. He has performed over 70 detailed reservoir studies worldwide; primarily in Southeast Asia’s low-contrast pay and carbonate reservoirs. Deakin’s proven approach is to identify and rank reserves uncertainties for operators and investors, then guide operators 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 IPRC, the industry’s benchmark petrophysics training course. This was followed by courses on Carbonate & Fracture Petrophysics IPCFR and focused modules on Quick Look Techniques IPQL, Using Modern Logs with SCAL IPSCAL, Low Resistivity Pay IPLAM, Saturation Height IPSWHT, Using PetroDB Effectively IPPetroDB and Renewable Energy REP.
Deakin’s core interest is the integration of diverse technologies to solve problems. Integration of the uniquely powerful PetroDB, cross-linked core-log-test database, with mainstream software is his current project. Deakin is an active member of SPWLA and occasional lecturer at Edit Cowan & Curtin University. His consulting company PETROPHYSICS Pty Ltd has offices in Perth, Australia and he has homes in Perth and London.
