Induced Polarization Relaxation Time Fractal Dimension Derived from Capillary pressure data for characterizing Shajara Reservoirs of the shajara Formation of the Permo-carboniferous Unayzah Group
Al-Khidir, Khalid Elyas . 2015
Geometric average relaxation time of induced polarization was derived from capillary pressure data to characterize the sandstones of the Shajara Reservoirs of the Shajara Formation of the Permo-Carboniferous Unayzah Group. The acquired values of the geometric time have been used to calculate the fractal dimension. Based on the obtained values of the fractal dimension as well as unconformity surfaces and mudstone separator, the Shajara reservoirs were divided here into three geometric time fractal units. The attained units from base to top are: Lower Shajara Geometric Time Fractal Dimension Unit, Middle Shajara Geometric Time Fractal Dimension Unit and Upper Shajara Geometric Time Fractal dimension Unit. The three Shajara reservoirs geometric time units have been also confirmed by arithmetic time fractal dimension.
