Abstract
A straddle packer for proppant-laden fracturing fluids has a slotted frac sub with a proppant filtration plug body that excludes proppant in the fracturing fluid from a central passage of the straddle packer downhole from the slotted frac hub. Pressure equalization sleeve filters exclude an entry of debris in a well bore through pressure equalization ports of the straddle packer.

A straddle packer with fluid pressure packer set for proppant-laden fracturing fluids, comprising a proppant filtration plug body that occludes a central passage of the straddle packer downhole of radial fluid paths through a frac sub of the straddle packer and uphole of fluid ports of a compression cylinder of the straddle packer, the proppant filtration plug, body excluding solid components of high-pressure fluid pumped into the central passage while permitting fluid components of the high-pressure fluid to flow therethrough.
A straddle packer with fluid pressure packer set for proppant-laden fracturing fluids, comprising a slotted frac hub having a central passage and at least one frac hub slot in fluid communication with the central passage, the slotted frac hub, supporting a proppant, filtration plug body that occludes the central passage downhole of the at least one frac hub slot, the proppant filtration plug body excluding solid components of high-pressure fluid pumped into the straddle packer from a central passage of the straddle packer downhole of the slotted frac hub, while permitting fluid components of the high-pressure fluid to flow therethrough.
