Hints On Pre- Miocne Carbonate Potentiality In Petrobel & Nearby Concessions, Centeral Province, G.O.S, Egypt

The giant oil exploration and production in the Gulf of Suez nowadays comes from classic sandstone reservoirs. Therefore, explorationists started to pay attention and goes through extensive studies to explore the potentiality and productivity of the Pre-Miocene carbonate developed sections. The studies still going on due to the unconventional and complexity of hydrocarbon habitat, source rocks, migration, seals and trapping mechanism which raise the exploration risks in the study area. In the light of encouraging scattered carbonate production since the last few years from Eocene, U.Senonian and Turonian reservoir, the main objective of this paper is to explain the carbonate exploration difficulties and trying to construct a structural model for the carbonate production.Also, to have a best fracture information to evaluate the carbonate reservoir potentiality since the primary porosity is rather poor To achieve these objectives an integration of geological, petro physical, petrography and engineering concepts have been done to trace and verify the fractured carbonate reservoir. The secondary porosity due to deformation of highly cherty limestone with respect to the trend logy, distribution and intersection of faults as well as dolomitization played the great role of defining the oil production either from normal carbonate oil fields or from scattered and single wells. The study supports horizontal drilling for the single well type of production rather than vertical drilling to enhance more contribution
