Drilling fluids/shaly rock interactions are known to be the main cause of wellbore instability problems leading to stuck pipe, extended drilling time and even sometimes abandonment of the well and, hence, great economic losses. Solution of wellbore instability problems, however, requires an integrated study of the mechanisms of drilling fluid/rock interaction including rock and drilling fluid characterization together with the investigation of the change in rock mechanical, physical and physicochemical properties.
