The productivity of sandstone or carbonate formations is enhanced by contacting the formation with a deformable particulate and a HF-containing acidizing solution. The deformable particulates create a partial monolayer in the formation while the HF-containing acidizing solution differentially etches the rock around the deformable particulate. The surface of the formation is partially blocked from reaction with the acidizing solution by the creation of the partial monolayer. Conductive channels are therefore created on the surface of the formation. The deformable particulates deform on closure. As the closure stress increases, the formation faces compress the non-dissolved, sandwiched formation points. These points function as pillars of un-reacted formation and act similar to a partial monolayer of proppant, providing the highly conductive channels.
