With reference to the reservoir characterization regarding the Khuff Formation – Khurtam Member (KSA), better reservoir quality prediction can be assigned to the characterization of its physical properties. These properties determination are depending on facies description. These properties can be erratic according to the diagenetic change and control on pore geometrical attributes and reservoir characterization. In this investigation, permeability and porosity have been measured in the laboratory. Rock Quality Index (RQI), flow zone index (FZI) as well as porosity groups have been calculated. The use of different determined physical and petrophysical parameters and their plots have defined two Flow Zone Indicators (FZI) characterized by a restricted distribution of porosity permeability and rock quality index. Different approval statements were made by correlation process. These confirmation and data support made of the considered reservoir as relative tight reservoir and tight reservoir. The use of the R35 was organized to make an approval to different statements with reference to the considered reservoir which can be classified as relative tight reservoir and tight reservoir. The R35 was carried out to
approve not only that the reservoir is relative tight and tight but it can be classified in the
range within the range of nano to microporous system.
