DOI: 10.1016/j.jngse.2017.04.027
Abstract: Abstract Compared with conventional porous-water-drive gas reservoirs, calculating the reserve of a fractured vuggy with water driving is a more difficult and challenging task because of its complex matrix types (matrix, fracture and cavity) and… read more here.

DOI: 10.1016/j.petrol.2018.12.014
Abstract: Abstract Universal existence of the filled vug or cave in carbonate reservoir complicates the fluid flow as the coexistence of free flow and porous flow. The fills in vug increase the flow resistance and affect… read more here.
