ABSTRACT:
A method of subsurface lubrication facilitates well completion, re-completion and workover while increasing safety and reducing expense. The method involves using a subsurface lubricator mounted to a wellhead of the cased wellbore to lubricate a downhole tool string into the cased wellbore by running a subsurface lubricator through the wellhead and into an upper section of a production casing of the cased wellbore.
