This course does more than calibrate your density log with core grain density and porosity. It starts with conventional core analysis laboratory procedures and the essential core-log integration techniques necessary to create the compatible data sets required for all special core analysis (SCAL) integration.  It then describes lab SCAL procedures for static and dynamic geo-models logically, in sequence, integrating SCAL results with powerful, modern logs to show how key reservoir parameters are better quantified with SCAL integration. NMR, Dielectric, Cross Dipole sonic, 3D resistivity, Lithoscanner and MDT are some of the logs whose output is cross-calibrated and welded into the fabric of a true, modern, integrated petrophysical evaluation. These evaluations are robust, over-determined and grounded in routine and special core analysis. Integration techniques are explained in terms of the question being asked, the physical basis of the core-log data being used and the steps necessary to quantitatively integrate the relevant SCAL with the logs and geo-models.  Like the author’s other “Integrated Petrophysics” courses a logical, systematic structure is followed which enhances understanding of the where, why and how of modern core-log integration.

Lithology, Porosity, Saturation Height, Absolute and Relative Permeability, Residual Oil Saturation, Natural fractures, FWL, TOC and mechanical properties for brittleness and fracturing are addressed, with the relevant special core and log data identified, explained and then carefully integrated within a logical framework using Interactive Petrophysics software.

Lectures are interleaved with micro-practicals, videos, PetroDB-WEB demos, class practical’s, class discussions and timely recaps to achieve a dynamic and engaging training session.

This course explains how to perform comprehensive core-log integration on legacy data and arms you with a clear understanding of what is and what is not critical to acquire in your particular reservoir, saving valuable time and money during drilling, completion and development.

Core-Log integration has been the central topic of the author’s Imperial College Ph.D. and over 25 years of consulting, reading and lecturing on core-log integration.  It is also the central purpose of the PetroDB-WEB software, which expands essential core-log integration to SCAL and modern logging tools.

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.
