Abstract

Prince Rupert drops are created by quenching molten glass. This results in a tremendous stored energy due to the rapid cooling effect from outside inward. The final shape has a large compressive strength (greater than steel). The remnant tail has a special trait, when sheared, releases this stored energy in an explosive manner resulting in the ball shattering into dust particles. This phenomenon opens itself to multiple downhole applications: disappearing plugs, disappearing shearable devices, etc. All will result in a fracture that have dust particles as the leftover material, therefore no post activation manipulation is required (i.e. drilling).
