The electrical conductivity of coal, at either 1 kHz or d.c., was measured at 24ยฐC on samples recovered from pyrolysis experiments aimed at modelling conditions during in situ gasification of coal. From an initial value of low3 S/m (when the coal is saturated with formation water), the conductivity
