Abstract

Previous HitForwardNext Hit Stratigraphic Previous HitModelingNext Hit (FSM) is the numerical simulation of the processes of erosion, transport and deposition of clastic sediments, as well as carbonate growth and redistribution controlled by the interaction of sea-level change, paleogeography, paleoclimate, tectonics and variation in sediment supply. The output of such Previous HitmodelingNext Hit may reveal the geometry and composition of the stratigraphic sequence This Previous HitmodelingNext Hit process and its results can be effectively integrated into traditional E&P workflows, improving them by transforming what is typically a static geometrical interpretation into a dynamic simulation based interpretation process. Our experience of applying Previous HitforwardNext Hit Previous HitmodelingNext Hit in other basins indicates that this approach may add value in addressing the challenges existing in the eastern Mediterranean. Basin scale FSM models help geologists to understand the big trends and to predict features that may be difficult to identify in the Previous HitseismicNext Hit Previous HitdataNext Hit. For example, backstepping deposits below Previous HitseismicNext Hit resolution, rift deposits in the deeper parts of the basin or diagenetic events. In turbiditic systems the distribution of architectural elements, sedimentary facies and rock properties are mainly controlled by sediment input, basin topography and syn-sedimentary tectonics. Previous HitForwardNext Hit stratigraphic models conditioned to honor well and Previous HitseismicNext Hit Previous HitdataNext Hit are inherently more predictive than other methods, particularly for those features below Previous HitseismicNext Hit resolution. Well correlation without a geologic concept can become a pattern recognition exercise. Previous HitForwardNext Hit stratigraphic models provide such geologic concepts to assist in guiding well correlation, in the same way stratigraphic models integrated with Previous HitseismicNext Hit Previous HitmodelingNext Hit help to improve the Previous HitseismicNext Hit interpretation process, particularly in the case of Previous HitseismicNext Hit stratigraphic interpretation. FSM allows for a structured approach in the search of stratigraphic traps. If the conditions for the creation of these traps can be identified in the model controls (sea level changes, syn-sedimentary tectonics, sediment inputs) and they can also be visualized in the model, then the basin location and the Previous HitseismicNext Hit signatures of the expected trap may be obtained. Previous HitForwardNext Hit stratigraphic Previous HitmodelingNext Hit of carbonate rocks is based on Previous HitmodelingNext Hit the growth of the different carbonate facies as a function of three main controls: wave energy dissipation, depositional water depth and suspended sediment. This approach allows the geologist to create predictive models of the distribution of the carbonate facies at both reservoir and basin scale. Previous HitModelingNext Hit of the controlling factors of the meteoric diagenetic processes helps to predict the intensity of these processes. These factors include: residence time (the longer a rock mass remains in the meteoric environment the more the diagenetic processes will progress), zone coefficient (specific diagenetic processes have different intensity in the different meteoric diagenetic zones) and a stratigraphic curve that simulates the effect of weather over the diagenetic processes (hot and humid weather will boost the diagenetic processes). The integrated product of these controls along with the model history computes a model property that, when parameters are properly conditioned to the hard Previous HitdataNext Hit, predicts the intensity of the diagenetic processes. These diagenetic attributes provide an aid in the search of reservoir intervals that may be invisible via other techniques. FSM can be applied from basin to reservoir scale and can be integrated with other basin or reservoir Previous HitmodelingNext Hit techniques to allow refinement of both the complexity of the Previous HitforwardNext Hit model and the accuracy of the hard Previous HitdataTop interpretation. In summary, FSM provides a reality check and a quality control for geologic concepts, bringing outcomes that improve many existing G&G workflows. It is expected that the application of this technology to the Eastern Mediterranean may improve the efficiency of finding new discoveries and enhanced recovery of existing fields
