Abstract: Unlined rock caverns for hydrocarbon storage are mainly excavated in strong and stable rock masses with very low-permeable matrix, where hydrocarbon migration is only possible along fractures connected to the cavern boundaries and their networks. In this paper, the hydraulic confinement around a URC cavern was simulated by directly applying distinct fracture network...
Abstract: Full-face shielded tunnel boring machines (TBM) including earth pressure balance (EPB) shields have been used almost exclusively for soft ground tunneling because of the many advantages the offer in comparison to the conventional methods. The total number of EPB-TBMs that were utilized for tunneling between 2005 and 2010 is approximately 350 units worldwide as reported by [1]. These machines...
Abstract: Widely utilization of large unlined rock caverns (URCs) located in water-bearing rock formations for hydrocarbon storage calls for more stringent hydrogeological precautions. Prediction of water inflow to the unlined caverns is one of such critical components faced by designers and hydrogeologist. Successful predictions of such issues require a thorough understanding of the physical processes...
