Summary

The structural configuration of Ras Budran field which lies in the northeastern offshore side of the G.O.S, is beyond controversy, considered as a complex Pre-Miocene model.

Oil is produced from a “NE” dipping Cretaceous and Paleozoic Nubian sandstone reservoirs which arc delimited to the cast and to the west by a set of nonclysmic “NE-SW” Cross Gulf faults, most likely contemporaneous with the Gulf of Aqaba, and transferred the older set of antithetic and synthetic gravity faults across, these “NE-SW” trending boundaries, structurally shaped Ras Budran field into parallel segments.

The intensive phase of Mid-clysmic tectonism during the Intra-Rudeis time produced uneven topography governing the successive deposition of the overlying sediments and was responsible for the field present day structure anomaly.

From the tectonic point of view, the Lower Miocene structural new model is very tempting to explain to what extent the structural set up controls the Pre-Miocene trap within the field and helps solving many of geologic and reservoir uncertainties.

The Nukhul and Rudeis formations are of prime interest in the study area where, the thickness distribution of these formations is widely differentiated and varies through out the field due to the variation in rates of tectonic subsidence and uplifting during the Miocene times however, this paper is an attempt to present the tectonic framework and its relationship to Intra-Rudeis Event which en ssence played an effective role on the field re-modeling.
