Two core plugs have identical porosity, mineralogy, and fluid saturation. Plug A has larger, better-connected pore throats than Plug B. Which statement is correct?

Plug A is likely to have higher permeability

In an unsteady-state pressure-pulse decay permeability test on a very tight core, why is this method preferred over a conventional steady-state flow test?

Because measurable steady flow rates are too small in very tight rocks, while pressure transient response can still be analyzed

Why is a Klinkenberg correction applied to gas permeability measurements on core samples?

To correct for gas slippage at low mean pressures and estimate liquid-equivalent permeability
