The role of stratabound fractures for fluid migration pathways and storage in well-bedded carbonates

摘要: Fracture analysis, carried out on two reservoir analogues cropping at Faito and Chianello Mts. (southern Italy) allowed us to unravel the role of stratabound joint networks for oil migration storage within well-bedded carbonate successions. The fracture regression analysis pointed that aperture increases as a function bed thickness according linear law, independently by lithological characteristics analyzed rock. Furthermore, statistical results suggest spacing exhibit, each value, lognormal probability distribution. estimation porosity identify, in sedimentary successions, three classes multilayer packages: ( i ) thin beds, characterized dual permeable pathways systems; ii medium sized showing limited permeability values iii thick acting highly negligible capacity. Our permit full characterization modeling networks. In particular, they provide powerful tool predicting preferential fluid major systems based data, framework an may be further enhanced integration petrophysics data.
