3D Geological Modeling for Characterizing the Bahariya Formation and Abu Roash G Dolomite Unit, Horus Field, North Western Desert, Egypt

The Horus field is considered one of the most important hydrocarbon producers within Alamein basin, Western Desert Egypt. This area was affected by different tectonic movements throughout geological history. re-evaluation and characterization area, especially its main reservoirs Lower Bahariya, middle upper AR/G Dolomite units, because low production oil tend (only 1100 BBD). Despite this, basin large very rich in hydrocarbon. study depends on interpretation thirty 2D seismic lines addition to open-hole logs form Resistivity, SP, GR, Density, Neutron, Sonic for five studied wells order delineate subsurface structure reservoir petrophysical characteristics field. data tried formation tops using synthetic seismograms. surfaces were mapped proceed with further static modeling. work flow 3D modeling Bahariya Formation Unit. processes that carried out during construction respectively, fault modeling, pillar gridding, skeleton grid, horizon zonation, layering, then distributed facies parameters (Vsh, Sw Φe) this model. objective phenomena structural, petrophysical, modelling (Lower, Middle, Upper) unit. depth contour map top unit indicated NW-SE WNW-ESE faults related lower Cretaceous. discussed possibility new structural traps benefit increasing area. All results consistent confirmed are excellent reservoirs. Integrating multidisciplinary methods interpretation, property well log analysis design models, helped predict exploratory promising areas increase reserves also decreasing uncertainty exploration.
