Facies analysis and reservoir rock typing studies are essential requirement for accurately understanding the performance and properties of the shaly sand reservoir challenge in the Nile Delta.
Reservoir rock typing is a method for reservoir rock classification into flow units with uniform pore throat distribution and flow performance. Core analysis is the direct method to measurement of the reservoir rock properties. Facies Analysis is interpreted from core data.
The Messinian Abu Madi clastic reservoir represents the first and great significant gas discovery in the onshore Nile Delta, the South Faraskour-3 well is representative of Lower Abu Madi reservoir in West El Manzala field, which is located in the eastern part of East Nile Delta Onshore at the western edge of El Manzala Lake and east of the Damietta branch. It is representing an executive example of the facies changes effect and various rock parameters in a shaly sand clastic reservoir in the Nile Delta area, which produces complex overlapping contribution in the production without distinguishing between these different units in the same productive reservoir.
According to this rock typing analysis results the Lower Abu Madi (LAM) productive reservoir can be segregated into three units: good, moderate and low according to quality of rock reservoir parameters and delineation of flow units. By tracing the facies which has the best flow performance along all the gas field reservoirs, leading to increase the productivity of the shaly sand Messinian gas reservoir of the Onshore Nile Delta.
