Abstract
A device and method allows a bore valve in the washpipe and in certain instances a port valve or sliding sleeve to open or close upon command from the surface so that gravel slurry may be placed in a wellbore.
Claims27
A system for packing an annulus of a borehole around a wellscreen with gravel from a slurry, the system comprising:
- a packer supporting the wellscreen in the borehole and having an internal seal in an interior of the packer;
- and
- a washpipe landing on the internal seal and having a crossover tool, the crossover tool conducting the slurry from the washpipe to the borehole annulus,
- wherein the internal seal of the packer comprises a first variable diameter seat having at least two first segments and a first receiver, the at least two first segments movable between first and second positions relative to the interior of the packer, the at least two first segments in the first position being unsealed with the washpipe, the at least two first segments in the second position sealing with the washpipe, and
- wherein the first receiver receives a first signal and moves the at least two first segments, in response to the first signal, between the first and second positions.

A system for packing an annulus of a borehole around a wellscreen with gravel from a slurry, the system comprising:
- a washpipe landing on an internal seal adjacent the wellscreen;
- and
- a crossover tool disposed on the washpipe, the crossover tool having a port for conducting the slurry to the borehole annulus and having a first variable diameter seat adjacent the port, the first variable diameter seat comprising at least two first segments and at least one receiver,
- the at least two first segments movable between first and second positions relative to an interior of the crossover tool, the at least two first segments in the first position for allowing fluid communication through the interior, the at least two first segments in the second position for closing off fluid communication through the interior and diverting the slurry to the port,
- the at least one receiver receiving a first signal and moving the at least two first segments, in response to the first signal, between the first and second positions.
