A simple inverse‐power relation for the influence of effective stress on permeability is used to explain the flow behavior during an injection test at the Higashi‐Hachimantai geothermal field, Japan. The new analytical expression successfully models data from the experiment involving high‐pressure injection and monitoring at an observation well.
