Abstract
Bottomhole assemblies (BHAs) are becoming much longer to carry equipment to the bottom of the hole. In many instances,<br>these BHAs can be many hundreds of feet in length and may need to be passed into a live well. Under traditional conditions,<br>a top-side lubricator is used and mounted directly to the wellhead to contain well pressure as tools are run into the hole.<br>However, with today’s longer-length BHAs, it becomes impossible to provide a lubricator with enough length to place on top of<br>the wellhead to run tools.
