This course does more than calibrate your density log with core grain density and porosity. It starts with the essential techniques of core-log integration required to create compatible data sets which are suitable for special core analysis (SCAL) integration. It then goes on to integrate the SCAL lab results with powerful, modern logs to show how these can be more usefully applied to answer key reservoir questions. NMR, Dielectric, Cross Dipole sonic, 3D resistivity, Lithoscanner and MDT are some of the logs whose output is calibrated and welded into the fabric of a true, modern, integrated petrophysical evaluation. Such an evaluation is robust, overdetermined and grounded in routine and special core analysis. All integration techniques are explained in terms of the question being answered (the objective), the physical basis of the core and log data being used and the steps necessary to quantitatively integrate the core with logs and geo-models. Like all the author’s “Integrated Petrophysics” courses a logical, systematic structure is followed which enhances understanding of the where, why and how of modern petrophysical data. Lithology, porosity, saturation, permeability, natural fractures, FWL, TOC and mechanical properties for brittleness and fracturing are addressed, with the pertinent core and log data explained and integrated.

Designed for you, if you are...
A petrophysicist, reservoir engineer, core analyst, geologist or engineer who builds or uses static or dynamic reservoir models
A professional with a year’s experience with core-log integration
How we build your confidence
Lectures are interleaved with micro-practicals, videos, PetroDB-WEB demos, class practicals, class discussions and timely recaps to achieve a dynamic and engaging training session - training which can be taken back to the office and applied immediately. This course explains how to perform comprehensive core-log integration on legacy data, but also arms you with the knowledge of what is and what is not critical to acquire in your 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., 30 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.
