Abstract:
A method of frac packing a well bore penetrating a subterranean formation, wherein the well bore contains a plurality of perforations in fluid communication with hydrocarbons within the formation, comprising:positioning in the well bore a tubular liner that contains a plurality of apertures such that the uppermost aperture in said liner is below the uppermost of said plurality of perforations in the well bore and such that at least a substantial portion of the apertures in said liner juxtapose a substantial number of the perforations in the well bore;introducing a frac pack slurry comprised of frac packing material suspended in a carrier fluid into an annulus that is defined between the liner and the well bore; andpumping said frac pack slurry at a rate such that bridging of the frac packing material does not occur at the top portion of the liner and such that the formation is fractured.
