ABSTRACT:
A system is provided for gravel-packing a zone of a well. An operating string of the system includes a liner hanger setting tool. A liner string is concentrically disposed about the operating string and has its upper end detachably connected to a lower end of the liner hanger setting tool. The liner hanger setting tool includes a rotatable ball valve disposed in a housing bore thereof. The liner string and operating string are lowered together on an outer drill pipe string into the well until a liner hanger of the liner string is located at a desired location. Then the liner hanger is set within the well at a desired location in response to an increase in pressure within the outer tubing string. Then the ball valve of the liner hanger setting tool is opened in response to an increase in pressure within a well annulus. A concentric inner tubing string is lowered through the outer pipe string, then through a ball valve bore of the open ball valve and into operable engagement with an isolation gravel packer of the operating string. Gravel laden slurry is directed down the concentric inner tubing string to a zone to be gravel-packed, and return fluid returns through a tubing annulus between the concentric inner tubing string and the outer tubing string.
