A method for treating a hydrocarbon-bearing rock formation (14). A colloidal suspension is introduced into the formation. An electrical potential gradient established by means of an anode (18) and a cathode (19) which produces osmotic forces which in turn cause stabilisation of the colloid. This increases the mechanical stability of the formation allowing the hydrocarbon material to be extracted while water production and sand production is suppressed.
