Structural control on the flow and accumulation of hydrocarbons in carbonate grainstones: an example from the Bolognano Fm. (Majella, Italy)

The thesis focuses on the structural analysis of several sets of fractures present in carbonate grainstones, at different stages of fault development. After characterizing the genesis and timing through detailed field observations, their spacing and length values has been measured to evidence different scaling distribution laws related to each set. Due to tar infilling in the fractures, the data, were used for geo-statistical analysis carried out to evidence which fracture characteristics determined hydrocarbon occurrence, and to evaluate the flow properties in this typology of reservoir.
