US Patent 12018537 Sand flushing above blanking plug

A system for producing fluids from a wellbore extending from a well surface to a fluid-producing formation has a Y-tool installed in fluid communication with the tubing string placed in the wellbore. A pump, which may be an electric submersible pump (ESP), is installed in the Y-tool for lifting fluids from the formation to the surface. A blanking plug is positioned in the tubing string between the upper and lower connections of the Y-tool. A flushing tank is run downhole to a position just above the blanking plug. Flushing fluid is dumped from an orifice or nozzle on the lower end of the flushing tank to agitate and disperse any accumulated sand, scale and other particulate matter on top of the blanking plug.
