1. Sub-Sector Description
Sub-Sector # 3 : W ell Servicing With Service Rigs Including Power Swivels
Well Servicing by means of service rigs including power swivels (Industry # 0 9903)
This industry is used to cover oil and gas well servicing operations which are conducted with the
use of well servicing rigs. Service rigs can be used on well completions once drilling operations
have been completed to bring a p roducing well on stream as well as work over service to existing
oil and gas wells. This industry is also used to cover the operation of power swivels used to
replace working components of service rigs and work over units.
Service rigs are smaller and more mobile than drilling rigs, (smaller to a l arge mobile crane) and
usually truck mounted. A s ervice rig operator, derrick hand and two floor hands usually make up
a s ervice rig crew. Most service rig operators will have shop operations for structural and
mechanical repair on their rigs.
Power Swivels are hydraulic motor driven pipe rotating machines specifically intended to replace
the drilling swivels, the kelly stem, the kelly bushing and the rotary table on service rigs and
work over units. They are trailer mounted and completely portable. Power swivel can be used to
provide rotary power for the internal cutting of casing, drill pipe and tubing for drilling out
packers, plugs, cement and other obstructions, for milling and scraping, drilling short distances,
coring and as a u tility tool in fishing operations.
