Abstract
East Ghazalat area is a proven hydrocarbon field within Abu El Gharadig basin, where multiple reservoirs are encountered ranging from Lower to Upper Cretaceous, oil and gas comes from the southern basin at the end Cretaceous, this is main time to accumulation of hydrocarbons, the migration process usually closer to the source, the vertical migration represent the main reason for the accumulation of the hydrocarbon through the active faults. Utilizing an intensive seismic survey and many wells this study have been carried out to establish the tectonic regime and activities affected the area during different geological ages with the aim to identify structural elements (Folds, Faults, inversion{u2026}etc.) developed and link these to the petroleum system. Structural and stratigraphic seismic attributes were also calculated to infer all main structural and stratigraphic trapping elements. Synthetic seismograms have been carried out for all available wells to tie horizons to seismic data and define the characters lateral variation of beds. Horizons of interest such as Apollonia, Abu Roash formation, Bahariya, Jurassic Masajid Carbonates, Upper and Lower Safa sandstone have been studied and mapped using the up-to-date technology of automated mapping through post stack seismic attributes volumes integrated with well data. Each horizon interpretation has been done in the time domain and velocity modeling represented bridges between the time and depth domains. The area under study is characterized by normal velocity behavior. This behavior is confirmed by the velocity surveys in the drilled wells and from new development wells drilled in the area. Seismic velocity model building for the entire study area is then developed using non-confidential data (sonic logs, time-depth pairs, lithostratigraphic marker depths and downhole position data) as well. The study inferred the location of at least more than one hydrocarbon bearing zone and prospects for shallow Apollonia leads
