  • Patent number: 11208869
    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.

  • Patent number: 10267120
    Abstract: Provided is an oil/gas service tool assembly. The oil/gas service tool assembly, in this example, may include a washpipe apparatus, the washpipe apparatus including an uphole washpipe portion, and a downhole washpipe portion having washpipe perforations therein, wherein the uphole washpipe portion and downhole washpipe portion are telescopingly coupled to one another. The oil/gas service tool assembly, in this example, includes a washpipe check valve coupled downhole of the downhole washpipe portion.

  • Patent number: 10041332
    Abstract: A working string is used to actuate a first valve of a completion string in a well to seal a float shoe of the completion string from a remainder of the completion string. The working string is also used to actuate a second valve of the completion string to seal the center bore of the completion string. Actuating the first valve and the second valve is performed without withdrawing the working string from the well. In certain instances, the working string is a washpipe that includes a shifting profile for each valve.
