The PetroQuip Phantom Glass Disk provides temporary isolation of the tubing or casing string for well construction operations. The proprietary glass disk is removed by applying tubing pressure to a preset shear valve. Once it shears, the glass shatters leaving no restriction in the wellbore. There are two different activation methods:
1. Shatter the disk with applied pressure
2. Mechanically break the disk
