27. A packer bypass assembly for connecting to and for use in combination with production tubing in a wellbore, comprising:
a packer for sealing an annulus between the packer bypass assembly and the wellbore such that, when sealed, there is an annulus above the packer and an annulus below the packer;
a primary bore for passing contents through the packer bypass assembly in a first direction, where the primary bore extends from a first terminal end of the packer bypass assembly to a second end of the packer bypass assembly;
a bypass path, separate from the primary bore, for passing contents from the annulus above the packer through the packer bypass assembly in a second direction, whereby the contents passing in the bypass path enter the bypass path at the first terminal end of the packer bypass assembly and exit the bypass path into the annulus below the packer,
wherein the bypass path includes a bypass inlet and a bypass outlet such that the contents passing in the bypass path enter the bypass inlet and exit the bypass path outlet, and
wherein the bypass path includes a check valve, located entirely between the first terminal end of the packer bypass assembly and the second end of the packer bypass assembly, that allows contents to flow in the bypass path only in the second direction.
