==Connectivity==
Even very large pores contribute nothing to fluid flow unless they connect to other pores. Connectivity increases with the size of pore throats and with increasing number of pore throats surrounding each pore. The number of pore throats that connect with each pore is the '''coordination number'''.<ref name=ch09r64>Wardlaw, N., C., Cassan, J., P., 1978, Estimation of recovery efficiency by visual observation of pore systems in reservoir rocks: Bulletin of Canadian Petroleum Geology, vol. 26, no. 4, p. 572–585.</ref>
