• said injector package is adapted to inject the wireline or coiled tubing into the well or well head,
• said lubricator means is adapted to be fitted in a lubricator package and define a locking chamber via which said wireline or coiled tubing is to be forwarded to the well or well head,
• said lubricator means being adapted to be connected to said well head,
• said injector package, comprises an injector module, being adapted to be fitted to said well head,
• and wherein the injector module is adapted to forward said lubricator means through it, when said packages are connected to each other and to the well head, for the purpose of injecting said wireline or coiled tubing into the well or well head, wherein
• the lubricator means comprises a lubricator pipe element and an associated moveable stripper/packer element adapted to be connected to a well barrier module on the well head.
