Abstract: A down hole apparatus for filtering debris from a fluid in a well bore including a screen sub, a diverter assembly connected to the screen sub, a screen section extending from the diverter assembly and connected to the screen sub. The screen section includes a plurality of openings for filtering debris from the fluid. The debris collects in an annulus between the screen section and the screen sub. The diverter assembly includes a detachable plug having a fishing portion capable of engaging a fishing tool. Removal of the detachable plug with a fishing tool opens a central passage through the diverter assembly and the screen section. The diverter assembly may include an outer and an inner body and one or more passages between the outer and inner bodies. The detachable plug may include one or more dog members capable of engaging the inner body.

Abstract: A screen apparatus for use in a well bore. The apparatus comprises a latch; a first tubular disposed within the latch, the first tubular having an internal retrieving profile; a screen extending from the first tubular, and wherein the screen contains a first portion with a first outer diameter, and a second portion that extends to a second outer diameter, and wherein the first outer diameter is larger that than the second outer diameter. The apparatus further comprises a diverter device operatively attached to an inner portion of the first tubular, and wherein the diverter device contains a passage to divert the fluid to an outer portion of the screen. In one preferred embodiment, the screen comprises a series of longitudinal slots of progressively smaller length. Also, the screen may contain a stepped outer diameter portion and inner diameter portion. A method of cleaning debris is also included.
