Understanding Pore Space through Log Measurements, Volume 76 looks at porosity distribution, pore shape and pore connectedness using log measurements that bring pore space into focus. This compilation of available knowledge will help interested readers better consider a focused integration to reservoir characterization, an area exploration and exploitation managers will find useful.

Key Features

  • Includes insights into the influence of pore attributes on macroscopic pore space descriptors
  • Covers grain characters that influence the properties of pore space
  • Includes fluid saturation and permeability from logs
  • Presents insights into how to best model the inversion of log data into these attributes


Geologists, Geophysicists, Exploration Geologists, Petrophysicists. Students pursuing post graduate studies / research in the field of reservoir characterization and Petroleum Geoscience Workers in the sedimentology field

Table of Contents

  • 1. Pore Space and its Classification – Different types of pores and their origin – Concept of different types of porosity – different models of pore space

    2. Porosity Estimation from Logs – Modelling grain properties and fluid saturation for estimating porosity from logs – Review of techniques of inversion of log data to gross attributes of the pore space

    3. Pore attributes for conventional reservoirs - Clastic and carbonate rock pore types - concepts of pore size - pore shape – surface to volume ratio – pore connectivity – pore compressibility

    4. Pore attributes for non-conventional reservoirs – Tight Gas Reservoirs – Basin Centred Gas Reservoirs – Shale Gas Reservoirs – Coals – surface to volume ratio – pore compressibility

    5. An overview of log measurements which help obtain pore attributes in respect of conventional reservoirs

    6. An overview of log measurements which are essential for understanding pore attributes and pore space attributes of non-conventional reservoirs

    7. Techniques for characterizing grains and pores from logs

    8. Archie’s cementation exponent–importance of, and salient features of effective medium theory based approaches

    9. Permeability of unimodal pore system– conventional reservoirs – unimodal porosity - the crucial role this porosity plays in controlling permeability–Permeability and Stoneley wave Propagation.

    10. Bi-Modal, Tri-Modal Pore Systems, Fractures
