ABSTRACT:
A well assembly for intervention of a subsea well or a well head with a wireline or a coiled tubing connected to a tool or a toolstring and including lubricator and an injector package. The injector package is adapted to inject the wireline or coiled tubing into the well or well head. The lubricator is adapted to be fitted in a lubricator package and define a locking chamber via which the wireline or coiled tubing is to be forwarded to the well or well head. The lubricator is adapted to be connected to the well head. The injector package includes an injector module adapted to be fitted to the well head. The injector module is adapted to forward the lubricator through it when the packages are connected to each other and to the well head, for the purpose of injecting the wireline or coiled tubing into the well or well head. The lubricator includes a lubricator pipe element and an associated moveable stripper/packer element adapted to be connected to a well barrier module on the well head.
