DEPLOYING AN ASSEMBLY INTO A WELL

摘要

Running an isolation device into the well and using the isolation device to form a seal to create a first region of the well isolating the surface of th e well from a second higher pressure region of the well, further including running an assembly into the first region and engaging the isolation device with the assembly to remove the seal. After removal of the seal, the isolati on device and assembly are run together further into the well. With this technique longer assemblies can be inserted into the well than is possible with possible with the use of a conventional lubricator.
