| Abstract | ||||
| In the Nile Delta province, approximately 88 trillion cubic feet (TCF) of gas reservoirs have been discovered. The main gas-producing rocks in EL Manzala Field are the Abu Madi Formation, a unit of gas-fertile rocks in the Nile Delta basin in the eastern part of the onshore Nile Delta, Egypt. Seismic data are the outputs of a convolution operation between the earth reflectivity and a source wavelet. Based on the results of the rock type analysis, the productive layers at the top and lower zones of Abu Madi Formation West El Manzala Field can be categorized into three units: good, moderate and low. In order to support the geologic interpretations for the area under study, the interpreter can gain more knowledge from conventional seismic data by using seismic characteristics. The seismic interpretation of Abu Madi Formation tops, average, interval velocity gradient maps, and time structure contour maps, followed by discussing the main attributes such as the envelope, RMS amplitude, instantaneous phase, instantaneous frequency, and relative acoustic impedance (RAI) are the most effective seismic features for displaying Abu Madi channel on the seismic sections. In addition, the study explained the existence of the sand reservoirs and the presence of hydrocarbon with different percentages in the Miocene section of the Manzalla gas field. | ||||
