A recently granted patent (Publication Number: US11884877B2) discloses a method for removing calcium carbonate fouling in reservoirs. The method involves aligning carbon dioxide with an atomizer to create a carbonic acid solution, adding a calcium carbonate fouling inhibitor, and pumping the resulting solution through lines into a well string within the reservoir. This injection process is followed by the displacement and injection of water and diesel plug into the reservoir.
The patent claims specify that the water used in the process can be industrial or desulphated water, with the volume of water injected being 1.5 times the volume of the well string. Additionally, the method is particularly effective for addressing calcium carbonate fouling located within carbonate reservoirs. By utilizing carbon dioxide and specific injection techniques, this patented method offers a novel approach to efficiently removing calcium carbonate fouling in reservoirs, potentially improving the overall productivity and longevity of oil and gas wells.
