Petroleum exploration is very difficult in Komombo basin due to the lack of information (Few wells and not cover the area). The present study aims to evaluate the Cretaceous reservoir represented by Abu Ballas (Aptian) and Six Hills (E. Cretaceous) Formations through the integration of available seismic and well data. The regional structural features are NW-SE based on depth structural contour maps constructed and the basin located at SE direction. Based on well data the stratigraphic section from basement to tertiary was intersected and penetrated. Stacked Seismic data alone cannot be used to predict reservoir properties. Therefore, Seismic inversion and attribute techniques were utilized to predict reservoir quality. Seismic inversion utilizes the seismic data, well logs, seismic velocity and interpreted horizons to generate impedance data. Distribute the acoustic impedance for reservoir rock (Abu Ballas and Six Hills Formations) through an applied seismic inversion technique, and through that detect the lithology for reservoir from the values of acoustic impedance. By integration seismic interpretation and seismic inversion, there are two leads with high quantities of oil (26 and 8.5 MMSTB in Six Hills E and Abu Ballas respectively). Seismic attributes were applied to detect structural and distribution of sandstone, shale and the distribution of relative acoustic impedance parameters in the area.

Komombo Basin Area covers an area of 186 km2 in the southern Western Desert of Egypt (Figure 1). Exploration in Komombo basin started in 1993 by Repsol Company with the acquisition of seismic data and drilling wells (Komombo-1, 2 and 3) exploration wells, both of them intersected Tertiary and Mesozoic strata and bottomed basement without identifying commercial oil or gas. Dana Gas Company explored Al Baraka oilfield in 2007 (Figure 1). The concession is situated in the Komombo Basin, located 800 km south of Cairo and is characterized by multiple stacked sand reservoirs. The Komombo Basin contains the producing Al Baraka oil field, covering a development area of 50 Km2.
