Abstract. 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.
