Abstract

Recent hydrocarbon explorations in the Gulf of Suez, Egypt have revealed relatively rich hydrocarbon accumulations, mainly of oil and/or gas, and demonstrate promising future prospects. In order to improve our understanding of this area and to provide a biostratigraphic framework and source rock evaluation for the poorly studied Miocene successions, a detailed palynological and palynofacies analysis has been undertaken. This investigation is based on 96 cutting samples selected from three wells drilled in the southern part of the Gulf of Suez, Egypt. These wells are: GH 404-2A Well of the Hilal Field, GH 420-1 Well (of the Ghara Field) and SA-E6A Well (Shoab Ali Field). The boreholes penetrated mainly Miocene strata belonging to the Nukhul, Rudeis and Kareem formations of the Gharandal Group. The majority of the samples proved palyniferous, yielding fairlyabundant moderately to well preserved marine palynomorphs (dinoflagellate cysts, microforaminiferal linings, scolecodonts and prasinophytes), and non-marine palynomorphs such as spores, pollen and colonial chlorococcalean algae. The dinocysts and sporomorphs enable biostratigraphic dating and correlation of these strata. Particularly rich and diverse palynomorph assemblages were recovered from the Rudeis Formation. In contrast, the Nukhul and Kareem formations yield only rare, poorly preserved and low diverse assemblages characterized by the prevalence of fungi and algae, particularly in the Nukhul Formation, close to the probable Oligocene/Miocene Boundary (OMB). The idea of the present work was to combine different methods in an integrative approach on the Miocene succession of the Gharandal Group of the Gulf of Suez, Egypt. Palynological, palynofacies, organic petrographic and organic geochemical techniques were used to obtain a reliable data set, to support the argumentations and discussions. In so doing, these investigations were focused on two main goals: (a) the palynology, palynofacies and organic geochemistry of the Nukhul Formation (b) the source rock evaluation of the Rudeis and Kareem formations in addition to a detailed systematic study of the recovered palynomorph assemblages. Afterwards, these investigations were published in 4 peer-reviewed articles in a cumulative manner.
