A method includes pumping cement to a bore of a shifting sleeve disposed in a ported component seated in a cased bore above a liner; flowing the cement from the bore of the shifting sleeve through radial passages of the shifting sleeve and radial passages of the ported component; and flowing the cement to an annulus between a casing of the cased bore and the liner.

Downhole cement flow

An assembly includes a ported component that includes a bore, radial passages, and axial passages; and a shifting sleeve that comprises a bore, radial passages, seal bosses and associated seal elements that define at least one sealed region with respect to the radial passages of the ported component and that define an open region with respect to the radial passages of the ported component.
