  • Pressure responsive below-packer valve apparatus
    Patent number: 5170844
    Abstract: A pressure responsive below packer valve apparatus which allows operation of a below packer valve through application of pressure to the wellbore annulus above the packer. The valve apparatus includes a crossover located in a tool string above the packer which communicates upper annulus pressure to a conduit inside the tool string. This conduit communicates annulus pressure to a valve mechanism below the packer. A selectively releasable mechanism such as a rupture disk communicates pressure to the valve mechanism once a threshold pressure is reached, thereby facilitating operation of the valve mechanism through application of annulus pressure.
