Claim Text:
1. A method of improving fluid outflow from a well borehole the method comprising the steps of: providing the perforating gun comprising a carrier for at least one shaped charge, the carrier being disposable in use within a well bore, the carrier comprising a housing at least partially formed from a composite material, the composite material comprising a polymeric reinforced material being non-frangible in normal use and the composite material being arranged substantially to contain debris created within the carrier as a result of firing the at least one shaped charge; positioning the perforating gun in the well borehole; perforating the borehole by firing the perforating gun such that upon firing the gun, the composite portion of the carrier therefore remains intact thereby containing debris from firing the shaped charge; retrieving debris resulting from the step of perforating by recovering the carrier of the perforating gun, whereby the carrier contains substantially all of the debris resulting from the firing.
