On a land drilling rig the tool pusher may be rig manager and responsible for all operations, but on drillships and offshore oil rigs, tool pushers are department heads in charge of the drilling department and reporting to the Master or Offshore Installation Manager (OIM) depending on the company - who in turn reports to a shore-based rig manager.
In recent times, tool pushers also have taken on somewhat of an administrative role, as they frequently do paperwork related to the rig crew regarding payroll, benefits, and related matters.
Tool pushers are also responsible for coordinating services with third party companies related to the drilling of the well.
Tool pushers usually start at an entry-level position (i.e., a roustabout or roughneck) and work their way up over time.
With the advancement in offshore drilling technology, cyberbase drilling experience is usually required before a driller can be promoted to the position of tool pusher.
