balanced plug

1. n. [Well Completions]
A plug of cement or similar material placed as a slurry in a specific location within the wellbore and which has set to provide a means of pressure isolation or mechanical platform. For correct placement, the volume of slurry and the displacement fluid must be carefully calculated and measured. The correct volume ensures that the column of fluid in the tubing string is balanced by the column of fluid in the annulus.
