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.
