Abstract

Permeability has been estimated making use of the concept of Flow Zone Indicator (FZI). Flow Zone Indicator has been obtained from the combined use of the well log data. Well logs are evaluated for porous and permeable sand layers. Permeability values have been calculated for three sand layers varying thicknesses from 4 to 9 m. Flow zone indicator (FZI) for porous and permeable layers from different wells are calculated from transformation of gamma ray, neutron porosity, density, deep resistivity logs. Calculated permeability value ranges from 11 md to 24 md for hydrocarbon bearing layers
