ABSTRACT:
Disclosed herein is a temporary well isolation device, which is sealingly disposable in downhole tubing, and which has a housing with an axial passage. The temporary well isolation device also has frangible barrier element within the housing, where the frangible barrier element is sealingly engaged in the passage blocking fluid flow through the passage. The frangible barrier element bears a load from fluid pressure. The temporary well isolation device also has a disengageable constraint in contact with a frangible barrier element so as to redirect the load on the frangible barrier element from a first component of the load to a second component of the load, thereby preventing rupture of the frangible barrier element. Also disclosed herein is a method for disintegrating a frangible barrier element disposed in a passage of a temporary well isolation device.
