The total cross-sectional area of the holes is preferably greater than the cross-sectional area of the inside of the casing. A plurality of stoppers are pumped in a leading edge of a cement slurry down an annulus between the casing and the wellbore to the tool where the stoppers engage the holes to hold the cement slurry in the annulus until the cement slurry hardens.
