AquaCUT™ relative permeability modifier (RPM) from Baker Hughes, is a subsurface water conformance product that decreases the water cut in mature sandstone wells, reducing associated processing and disposal costs while also extending the productive life of the well. By selectively targeting only the water phase of produced fluids, AquaCUT RPM products reduce the amount of produced water with minimal impact on hydrocarbon production.

AquaCUT RPM can be bullheaded or pumped through coiled tubing (CT) to target and dramatically decrease the water phase of produced fluids, including high-salinity brines. Although best used for reservoirs producing excessive water through matrix flow, AquaCUT RPMs can also be used for temporary mitigation of water production through water coning.

Wells that may have been shut in due to surface water handling/disposal can now be revitalized, increasing salable production. Less water means less build-up of scale, helping to decrease maintenance and treatment facility expenses. Decreased water production results in reduced water treatment and disposal, which helps to reduce CO2 emissions. Decreased water production also minimizes the cost of downhole pump repair and surface costs for storage and handling−improving lifting costs per unit of production. By increasing saleable production and reducing water production, AquaCUT RPM treatments can often yield impressive results in economic performance.
