Metal-to-metal seal success
Caledyne, a specialist inengineering services and products to the energy industry, is celebrating its first Asian installation of the Caledyne retrievable bridge plug (CRBP) incorporating the revolutionary Caledyne metal-to-metal seal. The CRBP is a high performance retrievable bridge plug which provides a complete metal barrier for in the well, capable of withstanding extreme temperatures and pressures. Installed for Talisman on the Bunga Kekwa project, Malaysia involved the installation of a 5 1/2-in CRBP to temporarily plug the BKC-20 gas well while a rig was mobilised carry out repair to the tubing string, immediately below the safety valve. The CRBP, which had never previously been used to seal against gas, was successfully set and sealed with zero leakage. Using the CRBP allowed Talisman to carry out its upper completion repair and provided a high performance barrier to safely isolate the well. The effectiveness of the technology, along with its short lead-time for delivery, has led to Talisman ordering several additional units for similar applications. |
