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 and in sequence, integrating SCAL with powerful, modern logs to show how key reservoir parameters are better quantified with SCAL integration. NMR, Dielectric, Cross Dipole sonic, 3D resistivity, Pulsar, 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 practical 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 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, Saturation-Height Functions, 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, practical exercises, 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.

Course Objectives
- To explain and demonstrate how new and legacy SCAL data can be integrated with conventional and modern logs to create a truly integrated, robust petrophysical evaluation which makes full use of the existing resources at no additional cost
- To explain how to identify and acquire key missing data
- To explain the lab and logging tool processes underlying the data to better understand how to use them quantitatively together. This leads to an understanding of what integration techniques to apply to what special core analysis data.
- To show how to use Interactive Petrophysics software to demonstrate how properly integrated SCAL and modern logs will impact your geo-model results.

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.
