Completing Long, Deviated Wells |
| 摘要 |
A buoyancy fluid is sealed in an interior central bore of a completion liner with a plug assembly in the interior central bore. The buoyancy fluid has a lower density than the fluid contained in the wellbore. The buoyancy fluid reduces the force, and thus friction, at the interface between the liner and the bottom of the wellbore while the completion liner is being run to final depth. When the buoyancy fluid is no longer needed, the plug assembly can be withdrawn uphole from the completion liner and to the surface. |

1. A method of installing a liner into a fluid containing subterranean wellbore, the method comprising:
sealing a buoyancy fluid in an interior central bore of the liner with a plug assembly in the interior central bore, the buoyancy fluid having a lower density than the fluid contained in the wellbore; positioning the liner to a specified final depth in the wellbore; withdrawing the plug assembly uphole; and after withdrawing the plug assembly uphole, flooding the liner with a fluid having a density greater than the buoyancy fluid. |
