Deducing the subsurface geological conditions and structural framework of the NE Gulf of Suez area, using 2-D and 3-D seismic data

Abstract

An interpretation of the seismic data of Ras Budran and Abu Zenima oil fields, northern central Gulf of Suez, is carried out to evaluate its subsurface tectonic setting. The structural configuration, as well as the tectonic features of the concerned area is criticized through the study of 2D and 3D seismic data interpretation with the available geological data, in which the geo-seismic depth maps for the main interesting levels (Kareem, Nukhul, Matulla, Raha and Nubia Formations) are depicted. Such maps reflect that, the Miocene structure of Ras Budran area is a nearly NE-SW trending anticlinal feature, which broken into several panels by a set of NWSE and NE-SW trending faults. The Pre-Miocene structure of the studied area is very complex, where Ras Budran area consists of step faults down stepping to the south and southwest, which have been subjected to cross faults of NE-SW trend with lateral and vertical displacements. ª 2015 Production and hosting by Elsevier B.V. on behalf

Petrophysical analysis and hydrocarbon potential of the Matulla Formation in the Muzhil Field, central part of the Gulf of Suez, Egypt

“…The termination of these oil fields is due to the intersection of the clays mic faults with the north oblique and/or northwest oblique faults. fault block started through the rifting phase during the Early Miocene, trap formation mainly occurred during the early rift rapid subsidence rate, affecting the pre-rift units (pre-Miocene) and early-rift units (Early Miocene) [49]. Faults formed during the Early Miocene which occurred first, followed by expulsion of the hydrocarbon, which creates the main oil in the field on its upthrown.…”

Source rock evaluation of the Central Gulf of Suez, Egypt: A 1D basin modelling and petroleum system analysis

“…According to EGPC (1996) and Fahmi, Attia, El-Tokhy, Saber, and Madkour (2015), the NW stretches of the Gebel Nezzazat tilted fault block started through the rifting phase during the Late Oligocene-Early Miocene, the trap formation mainly occurred during the earlyrift rapid subsidence rate, affecting the pre-rift units (pre-Miocene) F I G U R E 2 A generalized stratigraphic column of October oil field, showing the lithology distribution and formations thicknesses (Lelek, Shepherd, Stone, & Abdine, 1992) [Colour figure can be viewed at wileyonlinelibrary.com] and the early-rift units (Early Miocene). The main structure represented by horst, graben, and half-grabens take NW-SE direction (Fahmi et al, 2015), and October oil field is dominated by two fault trends, NE-SW and NW-SE (Zahra & Nakhla, 2015). Waples (1985) grouped source rocks into three kinds including effective source rock that generated and expelled oil and gas, possible source rock which may be generated and expelled hydrocarbons, and potential source rock which will be generated and expelled hydrocarbons according to the degree of maturation.…”

Petroleum system modelling and identification of promising oil and gas bearing objects in the eastern part of the Gulf of Suez, Egypt

“…The present considers hydrocarbon discoveries. Early attempts were made to describe how the basins formed, filled and distorted, focusing mainly on the pressure of sediments and the resulting rock structures [Al-Hajeri et al, 2009;Knebel and Rodriguez-Eraso, 1956;Weeks, 1952].…”
