Abstract (en)
[origin: EP2570586A1] An apparatus and method allow gravel pack slurry to be placed in a borehole annulus from the toe towards the heel to reduce the pressure acting upon the heel of the borehole during the gravel placement operation. By reducing the pressure on the heel,the gravel pack slurry may be placed in longer sections of the borehole in a single operation. Additionally, excess slurry in the inner string can be disposed in the borehole annulus around the shoe track of the apparatus, and fluid returns can flow up the apparatus through a bypass.
