- Sandstone formations
High water cut in oil and gas wells leads to a host of problems, and ultimately impacts the economic life of your well. Typical solutions are indiscriminate, blocking both water and hydrocarbon production, and often require costly workovers and long shut-in times. Specifically in mature fields, the cost and risks associated with these conventional methods outweigh return-on-investment.
水上屠夫™相对渗透率调节剂（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.
In the presence of oil, the AquaCUT RPM components deform and minimize the restriction of the formation pore throat, allowing oil or gas to flow unimpeded. Alternatively, in the presence of water, the water-wetting polymer expands, filling the pore throats which increases the resistivity of water flow.
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 CO2emissions. 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.
