Pore throat size and connectivity (view source)
Revision as of 21:12, 15 October 2014
, 21:12, 15 October 2014→Pore shape, throat size, and throat abundance
How do pore shape, pore throat size, and pore throat abundance affect the flow dynamics of a reservoir? Visualize a room with a door in each wall. The number of people who can fit into the room is a product of the size and shape of the room. The movement of people into or out of that room is a product of the size, shape, and number of doors. A large cubeshaped room with many small doors allows the people to leave the room at a given rate relative to a smaller tubular-shaped room with a few large doors.

A particular pore type has similar entrance/exit dynamics. Pore throats are the doors ('''ports''') to the pore. Along with S<sub>w</sub>, pore throats control [[permeability]] to hydrocarbons in reservoir rocks.
