Progress & Prosperityrock porosity and permeability within oil reservoirs.The four dimensional (4D) seismic surveyshave been recently introduced. This techniqueprovides information on the fluid movementswithin producing reservoirs.The accuracy of the results of the seismic surveysgreatly enhances the success of explorationdrilling.After obtaining these surveys and analyzinginformation, geologists team perform the nextphase which includes many geological studiesusing the information gathered through geophysicalsurveys in addition to information madeavailable from neighboring wells, if any. Someof these studies are mentioned hereunder:· Constructive Geological Studies:Concerned with the study of the Geology ofstrata based on the structure and the changesof the appearance of traps and potential for oilentrapment within oil traps in addition to identificationof types of folds and drifts that mayexist in the oil field and have positive or negativeimpact on traps according to type of layers.· Sedimentary Geological Studies:Geological Studies including the study of sedimentarysequences in respect to the type ofrocks and entrapment mechanism, migrationbefore or after the trap formation and also thepresence of the sealing rocks for hydrocarbonpreservation.· Basin Analysis:Concerned with the general studies of the sedimentarybasins and their distribution, the typesof the sedimentary rocks, the geologic structuresand the potentialities of hydrocarbon occurrencesand the optimum location of entrapment andthe nature of the reservoir rocks and its extensionand geographic distribution.· Geochemical Studies:Method involves chemical principle to characterizesource rock, its thermal maturity for hydro-10
