Continued pumping of cement slurry forces drilling fluid out of the casing interior, up the annulus and out of the wellbore. When the bottom plug lands at the bottom of the casing string, a membrane in the plug ruptures, opening a pathway for the cement slurry to enter the annulus. Engineers insert a top plug after the cement slurry, and the ...

Cement has a high affinity for water. So upon contact with water, the dry cement powder acts like a sponge and globs up. The balls form as these globs roll against the inside drum surface. The key to prevention is to program a material-loading sequence that deposits the cement and the coarse aggregate into the drum at the same time.
