Abstract
After installing an inventive tool attached to production tubing in a well, the well can be gravel packed without the use of a well intervention unit. The tool isolates a productive interval and diverts tubing-conveyed sand slurry towards an annular location by means of a port and an openable passageway restrictor. The entraining fluid component of the diverted sand slurry in the annular location is allowed to re-enter the production tubing through a first screen while the separated sand drops to the annular location to be packed in an axial direction. Rupture of a plug then allows the separated sand to be packed in an axial direction.
