Product Details
TBP and capping with cement can be a continuous plug operation resulting within one‑day. The plug is set in casing by compressing the seal elements causing expansion as the strong metal seal support and rugged anchors deploy. The compression is set with a long‑stroke wireline Bridge Plug Setting Tool (PST), and released after shearing a 10,000‑lbf tension stud. The plug can withstand pressure differential across the plug has been increased to 1000 psi or more in both directions. The drillable plug with a standard casing collar locator is used for depth control.
Applications
TBP abandons permanently an uneconomical horizon by Bridge Plug Setting Tool (PST) and it is widely used in workover, pay zones isolation and other constructions:
- Between zones, lower zone is producing water
- In perforations, the bottom part of a zone is producing water
- In sand screens, the plug serves as a diverter for sand/gravel consolidation via resins.
- In open hole, the plug differential rating is now a function of formation integrity.
Benefits
- Anchors center plug & tool even in horizontal wells
- Increase production by old well renovation
- No derrick and continuous plug operation resulting within one‑day, reduce the wellsite costs by saving time.
