The present invention relates to an approach to reducing or eliminating the plugging of slots in a slotted liner while otherwise allowing the liner to function in its normal capacity as a solids exclusion device which permits the reservoir fluids to flow through relatively freely. The approach taught by the present invention involves coating the surface of the slot with a suitable material. The coating at least partially covers the irregularities that are formed on the slot surfaces as a consequence of the slot manufacturing process. The presence of the coating results in a markedly reduced slot plugging problem while still enabling the slot to perform its main function in excluding or inhibiting the inflow of larger particles and allowing the inflow of fluids.
