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.
