This book offers a compact guide to geological core analysis, covering both theoretical and practical aspects of geological studies of reservoir cores. It equips the reader with the knowledge needed to precisely and accurately analyse cores.

The book begins by providing a description of a coring plan, coring, and core sampling and continues with a sample preparation for geological analysis. It then goes on to explain how the samples are named, classified and integrated in order to understand the geological properties that dictate reservoir characteristics. Subsequently, porosity and permeability data derived from routine experiments are combined to define geological rock types and reduce reservoir heterogeneity. Sequence stratigraphy is introduced for reservoir zonation. Core log preparation is also covered, allowing reservoirs to be analysed even more accurately.

As the study of core samples is the only way to accurately gauge reservoir properties, this book provides a useful guide for all geologists and engineers working with subsurface samples.

Dr Vahid Tavakoli is an Assistant Professor at the University of Tehran, Iran. He was awarded his Ph.D. in Petroleum Geology from the University of Tehran in 2011. Since 2012, he has been a member of the faculty in Petroleum Geology. From 2003 to the present, he has been working on core analysis of Iranian reservoirs. His particular research interests are reservoir characterisation using cores and wireline log data. He also has published over 40 research papers on reservoir characterisation, sea-level change, the geochemistry of reservoir rocks, and log analysis. He has been the team leader of several core analysis projects, and is currently heading an Iranian-Swedish project on Holocene core analysis awarded to him by the Swedish Research Council.
