1. A straddle packer with fluid pressure packer set for proppant-laden fracturing fluids, comprising a proppant filtration plug body with a sintered core that occludes a central passage of the straddle packer downhole of radial fluid paths in a frac sub of the straddle packer and uphole of fluid ports of a pressure cylinder of the straddle packer, the proppant filtration plug body being adapted to permit only fluid components of the proppant-laden fracturing fluids to flow therethrough.
