As the leading provider of advanced coiled tubing injectors, we understand the challenges faced in the field while running a complete coiled tubing system. We believe the heart and soul of any coiled tubing system is the injector head, and our line of patented injector enhancements provides solutions to common issues seen while running larger and more rigid pipe.
Many of the technologies are built-in to injectors currently running in the field, and upgrades are also available-regardless of electric or hydraulic injector cabin controls.
With the increased use of larger and stronger coiled tubing strings and overall increased tubing loads, injector chain lubrication is more important than ever. Our Injector Chain Auto-Lubrication (Auto Lube) System increases job reliability by automating the process. This system removes manual operation, ensuring lubrication is applied at appropriate intervals and in complete amounts throughout the job.
Our auto lube system reads the tubing speed from the CTES™ Orion™ data acquisition system or tubing encoder to calculate the chains' accumulated running feet. The system uses real-time operating data to determine the optimal start time and amount of lubrication while allowing manual intervention by the operator if required.
Previous Hydra Rig™ injector generations use a single motor to drive both chains, which results in the front and rear chains advancing at exactly the same number of chain pitches at all times. This causes a conflict with the chains gripping the tubing because the front and rear chains are never precisely the same length, even though they have the same number of pitches. When excessive traction pressure is used and the tension is not increased to compensate, the chains will time at both the tubing and drive system, resulting in the longer chain building up extra length and making the links stack up. The chain must slip microscopically on the tubing to make up the length differences while also gripping strongly enough to hold on to the tubing, which results in a narrowed window of acceptable traction force and increased injector wear.
Our hydraulic timing solution resolves both injector timing issues. Hydraulic timing allows only the traction zone section of the chains to be timed to each other while each chain shares equal load. In operation, the chains constantly shift slowly relative to each other based on the small differences in chain length, eliminating microscopic slipping. This elimination allows for improved gripping of the tubing for equivalent traction forces and extra traction pressure to be added without timing-induced chain stacking issues. Lastly, when tubing slips occur and the chains are no longer timed in the traction zone, hydraulic timing intervenes by keeping the chains close to the same speed, improving the injector's ability to regain control of the tubing, recover from a slip, and return to normal application.
Forces naturally accumulate between injector chains and coiled tubing as forces are passed, building over longer traction systems. These forces try to make the injector slip. Strain relief allows the grippers to momentarily let go of the coiled tubing, relieving the accumulated strain between the chain and coiled tubing in the long traction sections and improving the traction performance on high-strength heavy-wall coiled tubing. Strain, which accumulates over the traction length, occurs as the push or pull forces are transferred between the tubing and the chains.
Our slip mitigation system is engineered to remedy a major pain point-limited operator workforce experience. This system assists operators by providing an immediate increase in injector traction pressure when a tubing slip occurs and can react during an impending slip to prevent a slip from occurring. Today, few strings achieve their potential fatigue life due to mechanical damage caused by slips through an injector, and the slip mitigation system reduces this risk, prolonging string life, reducing downtime, and improving coiled tubing ROI.
The heart and soul of any coiled tubing system is the injector head, and our lines of injectors are recognized worldwide as the best in the market today.
Whether you are packaging a new, custom-built coiled tubing unit with a Hydra Rig™ injector or just replacing an existing one, our injectors have the performance and dependability demanded by the most challenging oilfield conditions around the world.
The hydraulically timed drive and free-floating traction systems (on applicable models) enhance performance and reliability in the field by reducing dynamic loads on the coiled tubing and injector components.

Designed to handle 2- to 2⅞-in. coiled tubing strings, this model is capable of running high-strength large-OD tubing designs with superior slow speed control (inches per minute). The HR-6120 has a 120,000-lb continuous lifting capacity and 60,000-lb continuous snubbing capacity.
Designed to handle 1¼- to 3½-in. coiled tubing strings, this model is capable of running large-OD tubing designs with superior slow speed control (inches per minute). The HR-6100 has a 100,000-lb continuous lifting capacity and 50,000-lb continuous snubbing capacity. The HR-6100 is lighter than its 5-series predecessor, which reduces impacts on coiled tubing unit transportation and hook loads and increases well control equipment (WCE) stack weight capacity below lifting equipment.
Designed to handle 1¼- to 3½-in. coiled tubing strings, this model is lighter and more compact than its 5-series predecessor, increasing flexibility for onshore and offshore deployments. The HR-680 has an 80,000-lb continuous lifting capacity and 40,000-lb continuous snubbing capacity.
Designed to handle 1- to 2⅜-in. coiled tubing strings with superior slow speed control (inches per minute), the HR-660 has a 60,000-lb continuous lifting capacity and 30,000-lb continuous snubbing capacity.
Designed to handle ¾- to 2⅜-in. coiled tubing strings with superior slow speed control (inches per minute), the HR-635 has a 35,000-lb continuous lifting capacity and 15,000-lb continuous snubbing capacity.
