Nile Delta.which covers a.proxim.0}ely 60,000 squa.e kilom.ters represents the m.st im.orta.t ga. province in Egypt wherea. its fields provide two-thirds of the ga. production in Egypt. The Nile Delta.province begins to displa. its hydroca.bon potentia.ity in the ea.ly 1960s. Nidoco field is loca.ed in the sha.low wa.er offshore Nile delta. a.u m.0}i form.0}ion (m.ssinia. a.e) is the m.st im.orta.t form.0}ion through a.l the section where it represents the m.0}n ga. producing reservoirs in the Field. The production of the field is com.ng from.two sa.d reservoir levels;a.u m.0}i level 2&3 which a.e cha.a.terized by fluvia.-delta.c sa.dstones. The purpose of this pa.er is to perceive the m.ssinia. ga. bea.ing reservoirs a.d cha.nelized sa.d distribution inside a.u m.0}i form.0}ion using seism.c a.tributes a.d a.plitude versus offset (a.O) technique. The results indica.ed tha. the seism.c a.tributes a.d a.O a.ded to give a.com.lete picture a.out the m.ssinia. reservoirs distribution a.d cha.a.teriza.ion in the field. a.so the results show tha. there a.e still prom.sing loca.ions of prospective a.u m.0}i Level 2&3 which a.e proposed to be drilled in the field.
