The present work is intended to summarize some observations derived from the structural seismic interpretation carried out in Abu Rudeis/Sidri field, based on the recently acquired OBC-2010. A new 3D OBC Seismic survey was acquired recently in the area in 2010 Showing a new and more interesting exploratory blocks in the Miocene (Nukhul Fm) and Pre-Miocene (Lower Senonian, Turonian, Cenomanian and Nubia sandstone) in addition to, the new un-conventional reservoir (fractured Igneous intrusions and meta sediments).
The study area is located within the north western of Red Sea-Gulf of Suez. The rift system is interpreted started around the late Oligocene and continue throughout the Miocene, and undertook extension in N650 W direction, nearly perpendicular to pre-existing WNW trending pan African shear Zone fabrics in the crystalline basement of the Sinai African plate.
The interpreted fault pattern is characterized by a series that comprises two sets of faults. The first corresponds to the northwest-southeast trend, which bound the study area from the South, offset fault segments throughout ramp relay structures, with maximum throws around 1000 m, juxtaposing Eocene-Paleocene sediments from the down-thrown block (basin wards) against the basement in the up-thrown block, the second system trends northeast-southwest and is interpreted as a later evolution of the rifting this last mainly strike slip and, the pre-existent northwest-southeast trending off-set fault segments by breaking the ramp relay structures.
As a fruitful result of the new 3D-OBC seismic survey, a positive result of the drilling good discovery proved the presence of the hydrocarbon potentialities and proved the conventional and unconventional reservoir.
The summary of these observations regarding the tectono-stratigraphic evolution of Abu Rudeis field area advocates both, remaining field exploration and development opportunities.
