Abstract
A method and assembly for treating a portion (e.g. horizontal) of a wellbore for removing solids and for producing fluids therefrom. The assembly is comprised of dual flowpaths (e.g. tubing strings) extend from the surface into the portion of the wellbore to be treated and produced. A liner is connected on the lower end of the first flowpath while the second flowpath terminates within the upper end of the wellbore portion. A treating fluid is flowed down the first flowpath and through the liner into the wellbore to wash and entrain solids therein. The treating fluid and solids are then circulated back to the surface through the second flowpath. After treatment, the second flowpath is closed and fluids are produced through the liner and to the surface through the first flowpath.
