| Abstract | ||
| The clastic sediments of the Abu Madi Formation host the main gas bearing reservoirs in the Nile Delta, Egypt. The current study integrates seismic and well logging analysis in order to shed light on the Abu Madi formation in Salma delta gas field which locates outside the Abu Madi main canyon. In the study area, Abu Madi Formation consists of sandstones, siltstones and shales which infill the subaerial channels of the low-stand canyons incised during the Messinian salinity crisis (MSC). The pay zone sandstones are thicker on the channel margins and on the upthrown parts of the faults, whereas the sandstones in the downthrown regions are often saturated with water despite their high porosity and low contents of clays. Therefore, Salma delta-1 and Salma delta-2 wells drilled on the channel margins are the best productive wells. The pay zone sandstones are characterized by dominantly quartzose composition with low clay (< 30%) and carbonate cement contents. The clays are often present in laminated forms, and therefore have minimal impact on porosity. The current study reveals that the best productive intervals of Abu Madi sandstones are preferentially accumulated on the channel margins and on the up < br />thrown side of the main faults | ||
