Conventional slurry packing methods involve a screen and from 120′ to 160′ (36.5m to 48.7m) of blank pipe above the screen. The blank pipe acts as a sand reservoir for the gravel pack screen.

To help ensure a good gravel pack job in a well that has less blank pipe than screen, a multiple stage slurry pack process was designed along with a multiple stage crossover tool.
