Abstract
A completion assembly facilitates gravel-packing and fracturestimulation of closely spaced zones. The assembly includes a pair of spaced screens with a production packer in between. The production packer has a short bypass flowpath therethrough to allow fluids carrying the gravel to pass the production packer so that the upper and lower zones can be gravel-packed simultaneously, as well as fracture-stimulated simultaneously. Thereafter, the presence of the gravel in the bypass tube in the packer between the zones provides some limited isolation based on the permeability of the gravel found in the bypass passage and the pressure drop across that passage. Production then can follow from the lower zone, the upper zone, or both zones depending on the completion configuration.
