ABSTRACT:
An apparatus to be disposed within a wellbore includes a production tubing in communication with a pump string and a bypass string at its distal end, wherein the pump string is configured to pump a wellbore fluid to a surface location through the production tubing, wherein the bypass string includes an upper fluid gate, a packer and a lower fluid gate, wherein the upper and the lower fluid gates are configured to selectively allow or disallow fluid communication with a bore of the bypass string, wherein the upper fluid gate is positioned above the packer and the lower fluid gate is positioned below the packer. The apparatus includes a check valve to prevent reverse fluid communication from the production tubing to the pump string.
