摘要:A method and assembly for treating a portion (e.g. horizontal) of a wellbore forremoving solids and for producing fluids therefrom. The assembly is comprised of dualflowpaths (e.g. tubing strings) extend from the surface into the portion of the wellboreto be treated and produced. A liner is connected on the lower end of the first flowpathwhile the second flowpath terminates within the upper end of the wellbore portion. Atreating fluid is flowed down the first flowpath and through the liner into the wellbore towash and entrain solids therein. The treating fluid and solids are then circulated back tothe surface through the second flowpath. After treatment, the second flowpath is closedand fluids are produced through the liner and to the surface through the first flowpath.
