Abstract

Provided is a packer plug. The packer plug, in this example, may include an engagement member having a no go feature configured to engage a no go shoulder of an associated packer assembly. The packer plug, in the example, further includes a nose cone having one or more nose cone openings coupled proximate a downhole end of the engagement member, and a check valve coupled proximate the engagement member. The check valve, engagement member, and nose cone, in this example, create a fluid path between a lower end and an upper end of the packer plug. Further to this example, the check valve is configured to allow downhole fluid to pass uphole through the fluid path as the packer plug is being pushed downhole, but substantially prevent uphole fluid from passing downhole through the fluid path as the packer plug is being pulled uphole.
