Abstract
An electric submersible pump (ESP) is coupled with a spaced apart debris removal assembly that is independently supported from a retrievable packer. The debris removal assembly is modular and retains the captured debris for subsequent removal from the well with the retrievable packer. The ESP suction draws in well fluids through the debris retention device. The ESP can be pulled to allow removal of the retrievable packer with the debris removal assembly.
