The new discoveries recorded within the Nile Delta province throw light on the need to explore more, which encouraged using integrated studies to evaluate the petroleum systems in the offshore eastern Mediterranean area. The purpose of this study is characterizing the stratigraphic patterns, evaluating the reservoir features and identifying the depositional elements of reservoir sediments (Upper Pliocene Kafr El Sheikh Fomation) in Hap'y-2 well, Ha'py Field, eastern offshore region of the Nile Delta, Egypt.  These objectives were realized using the analysis of core data, wireline logs and composite log. The results showed that the primary sand reservoir in the Hap'y-2 well is unconsolidated and the predominant control on reservoir quality is detrital clay content. The results of integrating well data analysis and core data indicate that A20 reservoir sand is an excellent example of a wave-dominated delta with a significant river effect. The extensive river input sediments are delivered to the sea, which reworks the majority of the sediments and a spit barrier system. The upper A20 unit is a shallow marine environment sand bar or shore face elongated sand bar complex. Subsurface data show that Hap'y-2 well contains at least two stacked sand bars (mounds).
