Abstract
The invention comprises a novel nozzle for use in wellbore tubing strings. The nozzle has an annular cylindrical nozzle body surrounding a frangible material. The frangible material is bonded to the nozzle body forming a seal. When deployed in a well, the nozzle prevents fluidic communication between the inside of the tubing string and an annulus of the well. A further component of the nozzle may comprise a stress riser that, when actuated, breaks the frangible material, allowing fluidic communication between the inside of the tubing string and the annulus of the well. Subsequent well operations (e.g., fracturing or production) may then be conducted.
