Anyone with experience in water control? (rpm and gels)

Hello people,

Has anyone some sort of experience with rpm (relative permeability modifiers) or gels for water control?

I would like to read about your experience using this products in gas or oil wells. Did they work? Any success rate? What the porcentage of water you managed to reduce? How long does the effects last? Did were used in volumetric, gas cap or water drive reservoirs?

Thanks in advance

Literature is plenty of good references, I would recommend you:
