Ali Jelvegarfilband; Mohammad Ali Riahi; Majid Bagheri

Volume 11, Issue 1 , January 2022

  The petrophysical parameters of the Ghar Formation are characterized in this study. A combination of pre-stack seismic data gathers and well-log data is used to estimate water saturation and shale volume in the Ghar reservoir. For such a purpose, first, the highest possible correlation between the well ...  Read More

An Improvement in Cation Exchange Capacity Estimation and Water Saturation Calculation in Shaly Layers for One of Iranian Oil Fields

Masoumeh Bashiri; Mosayyeb Kamari; Ghassem Zargar

Volume 6, Issue 1 , January 2017, , Pages 45-62

  Water saturation and cation exchange capacity are the most significant parameters used to calculate a hydrocarbon zone potential. In clean formations, by applying the famous Archie model, which assumes that in the formation the only electric conductor is the formation water, the water saturation can ...  Read More

A New Cementation Factor Correlation in Carbonate Parts of Oil Fields in South-West Iran

Saeed Rafiee; Abdolnabi Hashemi; Mohammad Shahi

Volume 3, Issue 2 , April 2014, , Pages 1-17

  Petrophysical parameters such as porosity, water and oil saturations, formation resistivity factor, etc. describe the storage capability of the porous media or the capacity of rocks to hold fluids. The modified Archie’s equation    . / . , also called the saturation equation, is used ...  Read More
