Significant structural reinterpretation of the subsalt, giant October Field, Gulf of Suez, Egypt, Using SCAT, isogon-based sections and maps, and 3-D seismic

The Gulf of Suez between central Egypt and the Sinai Peninsula is a transtensional rift structurally related to the Red Sea pull‐apart and the left lateral Dead Sea transform system. The Gulf went through a major period of transtension in the Miocene coeval with the Alpine orogeny in Europe. The major structures are homoclines bounded by a major east‐ or west‐verging, extensional fault, locally termed the Clysmic Fault, whose systems provide the updip trap by sealing Cretaceous and other pre‐Miocene reservoirs against syn‐ and post‐ extensional shales and evaporites.
