Although the equation was developed for a bundle of capillaries it is still assumed to apply for real porous rocks and b will be specific to a particular plug. 04 mm (or a hundred molecular diameters). At reservoir conditions, it will be at least an order of magnitude less. Although these are small relative to the pore throats in a conventional reservoir rock they are large enough to have noticeable effect and typically permeabilities reduce by 10% on going from ambient to reservoir pressures. For tight gas reservoirs with permeabilities of the order of microDarcy the pore throats are much smaller and the Klinkenberg corrections can be substantial (50% or more).

This is referred to as ‘dispersed shale’ (although it ought to be called ‘dispersed clay’). In the Morecambe gas fields in NW England the presence of a few per cent by volume of illite is sufficient to reduce permeability by a factor of a thousand. Three cases are illustrated by sketches in Fig. 9. Most logs lack the resolution to distinguish these different cases and will simply show log responses that are intermediate between clean sand and pure shale. In any case the three cases are really end members and all three may be encountered at the same location.

There are two main reasons for the disagreements: 1. Natural variability in the composition of the clays. 2. Definition of what is pure clay. There is not much that can be done about the natural variability.
