85AbstractReservoir rocks are not mostly clay free The type of clay mineral and its distribution affectthe properties of the reservoir rock Clays can change porosity permeability and effect loggingtools response Shale can effect on reservoir quality if the effect of shale on porosity andpermeability is ignored that can effect on reservoir final estimation Porosity which is one ofthe important characteristics of reservoir is measured using sonic neutron and density log These logs are strongly affected by shale The shale in the formation due to the presence ofclay mineral with the content of water affects the hydrogen response of these logs from theformation Therefore the porosity calculated from the neutron and density log regardless ofthe shale volume have error As a result it is necessary to take into account the exact volumeof shale in the porosity calculations resulting from logging In the present study naturalgamma neutron density porosity log M N and Holgs Lehmann averaging methods andneutron gamma cross plot were used to estimate the shale volume The results of thesemethods were compared with core analysis studies in different depths Generally theconclusion obtained from shale volume estimation using natural gamma neutron density porosity log M N Holges Lehmann averaging and neutron gamma cross plot shows themethod of using the corrected gamma ray log CGR and the combination of the three porositylog M N give a good estimate of the shale volume In cases where gamma ray diagrams arenot available in the well under study the M N method provides a good estimate of shalevolume compared to other methods It seems that the presence of lithological variability at acertain depth affects the estimation of shale volume using any of the methods In general corrected gamma ray CGR seems to be more efficient in variable lithology Keywords Clay Shale volume Natural gamma ray Shale index Geolog Well logging
