Abstract
A downhole well tool includes a tubing including a circulation fluid pathway, a first packer, and a second packer positioned longitudinally apart from the first packer. The well tool includes a circulation sub connected to the tubing on a first longitudinal side of the second packer, the circulation sub including a first circulation port to fluidly couple the circulation fluid pathway to an annulus of the wellbore, and a plug seat positioned in the fluid circulation pathway. A second circulation port in the tubing is positioned longitudinally between the first packer and the second packer, and fluidly couples the circulation fluid pathway to the annulus of the wellbore between the first packer and the second packer. The second circulation port includes a frangible cover that plugs the second circulation port and ruptures in response to a burst pressure in the circulation fluid pathway.
