Abstract
A pressure barrier apparatus 2 for providing a removable pressure barrier in a borehole is described. The apparatus comprises a housing 6, 8 defining a central bore 10 having a first part 20 and a second part 22 separated by an erodeable pressure barrier member 18. The housing also defines a second fluid flow passage 12 for connecting the first part to the second part, and a plurality of conduits 24 for directing fluid onto the barrier member to cause erosion of the barrier member. A sleeve 30 has a first condition in which fluid communication between the first part 20 and the second fluid flow passage 12 is prevented, and a second condition in which fluid is permitted to flow from the first part to the second fluid flow passage to cause erosion of the barrier member.
Claims12
A pressure barrier apparatus for providing a removable pressure barrier in a borehole, the apparatus comprising:
- a housing defining a first flow passage having a first part and a second part separated in use by an erodeable pressure barrier member, a second fluid flow passage for connecting said first part to said second part, and at least one conduit for directing at least a portion of fluid flowing in said second fluid flow passage onto said barrier member to cause erosion thereof.
A removable pressure barrier apparatus for location in a borehole, the apparatus comprising a housing defining a fluid flow path, and a pressure barrier member adapted to block fluid flow in said flow path and to be eroded by means of fluid flow to permit fluid flow in said flow path.
