Seismic Time Fractal Dimension for CharacterizingShajara Reservoirs of The Permo- CarboniferousShajara Formation, Saudi Arabia by Khalid Elyas Mohamed Elameen Alkhidir in Modern Approaches in Oceanography and Petrochemical Sciences (MAOPS)- Lupine Publishers

The quality and assessment of a reservoir can be documented in detail by the demonstration of seismic time. This research aims to calculate fractal dimension from the relationship among seismic time, maximum seismic time and wetting phase saturation and to approve it by the fractal dimension derived from the relationship among capillary pressure and wetting phase saturation. In this research, porosity was measured on real collected sandstone samples and permeability was calculated theoretically from capillary pressure profile measured by mercury intrusion contaminating the pores of sandstone samples in consideration. Two equations for calculating the fractal dimensions have been employed. The first one defines the functional relationship between wetting phase saturation, seismic time, maximum seismic time and fractal dimension. The second equation involves to the wetting phase saturation as a function of capillary pressure and the fractal dimension. Two procedures for obtaining the fractal dimension have been utilized. The first procedure was done by plotting the logarithm of the ratio between seismic time and maximum seismic time versus logarithm wetting phase saturation. The slope of the first procedure = 3- Df (fractal dimension). The second procedure for obtaining the fractal dimension was determined by plotting the logarithm of capillary pressure versus the logarithm of wetting phase saturation.
