Abstract
Nile Delta is one of the most popular deltas around the world, besides, it is the most important gas proven in Egypt as well. It is located to the northern side part of Egypt. Looks as a V-shape or triangle-shape, in which, the apex located to the north from Cairo. The present Nile Delta covers an onshore area of about 30,000 km2 and about an equal size offshore down to the 200 m isobath.
The major structures of the Nile Delta had played an important role in the forming of the hydrocarbon system. Pre-Miocene formations are affected by a prominent flexure zone that has evolved and extends from east to west across the mid-Delta region (the hinge zone). The hinge zone is a faulted flexure zone of 30-40 km width. Its age was determined to be in the Jurassic, at the time of a crustal split that separated the southern stable platform (South Delta block) from the northern subsided basin, where all Cenozoic sequences have thicker and relatively deep marine successions. The Nile Delta is differentiated into two geological provinces that are the deep offshore Nile Delta and the onshore Nile Delta. The onshore Nile Delta region is divided by the flexure zone which is known as a hinge line into two structural sedimentary sub-provinces that are the South Nile Delta block and the North Nile Delta basin.
The study area is located in the central part of the Nile Delta. It covered the development leases that are, from south to the north, Khilala, Abu Madi, El Qara, Abu Madi West, and Baltim. And constrain on the Middle-Upper Miocene section because of it considered as the main gas target in the study area.
The previous geological data interpretation contains a lot of misunderstand about the reasons of some dry wells, the difference in the water level and pressure regime, and other ambiguities of the geological data concepts that causes a misleading in the understand of the production’s behavior of the different reservoirs. All of this blind geological interpretations due to the use of the 2-D seismic data which was the only available seismic data in that time. Besides, the Upper Miocene section was a barren zone (no fossils found).
The aim of the present study is to differentiate between the different rocks depending on the new seismic interpretation – after the 3-D seismic data – and the interpretation of the well log facies together.
The procedure depend on the utilizing of the advanced seismic interpretation in distinguish between the different rocks besides the well data logs. The advanced seismic interpretation that had been used are the seismic amplitude, reflection strength, sweetness, and the fault likelihood attributes. Another powerful toll is to use the fluctuating in the gamma ray log to expect the different depositional environment.
The integration of the new seismic interpretation and the well log facies interpretation resulting in a new geological model, in which, all of the previous geological data ambiguities had been declared.
