... velocities can be calculated allowing direct correlation of laboratory displacement test results. Introduction The migration of small solid materials ("lines") within porous media has long been recognized as a source of potentially severe permeability impairment in formations containing oil and gas. Fines...

The treating fluid, which slowly generates hydrofluoric acid (HF), reacts more slowly than conventional Mud Acid and thus penetrates a greater distance into the formation before...
