Abstract
A retrievable string configured to be positioned in a well is described. The retrievable string includes a rotating portion and a non-rotating portion. The rotating portion includes a rotor configured to be positioned in and driven by a stator of a well completion. The rotating portion includes an impeller coupled to the rotor. The non-rotating portion is cooperatively configured with the impeller to induce fluid flow in the well in response to the stator driving the rotor. The non-rotating portion includes a coupling part configured to support the rotor positioned in the stator. The coupling part is configured to detachably couple to a corresponding coupling part of the well completion.
