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. See more How do pore shape, pore throat size, and pore throat abundance affect the flow dynamics of a reservoir?
