Workover Rigs & Well Intervention Equipment
Time Rolling supplies workover rigs, snubbing units and flush-by rigs for oilfield well servicing. Choose equipment for the required lifting load, intervention method and operating environment.
- Workover rig static load
- 300–2,250 kN
- Installed power range
- 235–1,300 HP
- Workover · snubbing · flush-by
- 3 equipment types
Mobile workover rigs
The workover rig range includes TRXJ150, TRXJ250, TRXJ350, TRXJ450, TRXJ550, TRXJ650, TRXJ1000 and TRXJ1200. Maximum static loads range from 300 to 2,250 kN (67,440–505,800 lb), with installed power from 235 to 1,300 HP.
Chassis-mounted operating equipment supports rapid relocation and installation. A self-propelled chassis is designed for off-road travel, while the engine and hydraulic transmission use components from established manufacturers.
- Mast designed to API Specification 4F.
- Integral Lebus grooves in the main drum guide the line and help prevent entanglement.
- A transfer case distributes engine power to the chassis and deck equipment.
- Configurations include double fastline, dual power, free-standing and self-tightening guyline rigs.
- Desert, mountainous, cold-weather, light-duty and trailer-mounted options suit different field conditions.
Snubbing units
Time Rolling snubbing units support downhole intervention without first killing the well or releasing well pressure. Truck-mounted, trailer-mounted and skid-mounted configurations are available for onshore and offshore operations.
The equipment combines a central control system, hydraulic lifting system, fluid monitoring and handling equipment, and a blowout preventer (BOP). PLC controls support automated operation.
Flush-by rigs
A flush-by rig combines mobility with mechanical drawworks for routine well intervention. It can handle casing and small tubing strings in water wells less than 1,000 m deep, as well as selected oilfield servicing tasks.
Unlike a conventional flush-by unit, this design uses mechanical, single-wrap drawworks. Power tongs help improve handling efficiency and protect rods during servicing.
- Backflush sanded wells and remove sand, wax or other pump-intake and discharge blockages.
- Install insertable downhole pumps and fish or repair broken sucker rods and polished rods.
- Service driveheads and stuffing boxes, perform production flushes and assist coiled tubing operations.
- Maintain or close water wells using small casing strings.
- Provide sand-dissolving and unfreezing service for heavy-oil wells with screw pumps.
- Working temperature
- −20 °C to +50 °C
