Storm Plug
Requirement:
- Temporary bridge plug required for large diameter, non-API casing due to impending storm
Solution:
- Run Single Set inflatable packer and set below sub sea safety systems
- De-mobilize rig for storm
- Return to location & latch onto packer
- Expel plug from ID of packer & check for pressure below
- Release packer and POOH
-
Continue operations

Gulf of Mexico:
Challenge:
- An exploration well in 8,000’ of water in the Gulf of Mexico with 24” casing set was temporarily plugged to allow disconnecting of the riser from the BOP stack while a hurricane raged through the Gulf.
Solution:
- A 14-½” OD Inflatable Bridge Plug (IBP) was run and set 1,400’ below the BOP/well head
- BOP were closed, 22” riser disconnected and picked up 400’ to allow ship to move freely during the storm.
- After storm passage, the riser was re-connected, BOP tested and the IBP retrieved to allow continuation of the drilling operations.
Value Added:
- Prior methods of using cement plugs had proven ineffective due to low fracture pressure and associated losses when the cement plug is placed.
- In addition, rig time required to place and drill out cement plugs was greatly reduced by using the IBP.
