• Matrix-fracture Fluid Transfer, Naturally Fractured Reservoirs
• Dual Continua Formulation
• Shape factor

After 60 years of worldwide scientific efforts, the authors do not see a chance of formulating the matrix-fracture mass transfer rate, as it happens in naturally fractured hydrocarbon reservoirs, in one, generally applicable expression. Numerous approaches for it have been presented, but none of them considered all possible conditions and for none of them experimental evidence was presented. Therefore, the only consistent approach is a numerical calculation on a fine scale single matrix block (SMB) model. Heinemann (2004) suggested using the recovery curves resulting from SMB calculation directly in any dual continuum formulation. Mittermeir (2015) did so in material balance calculation. It is proved that this approach has the potential for being generally applicable.
