Tubing Rotator Questionnaire


We also have a Print Version of this questionnaire available here.



The first thing that needs to be established is if the well is a candidate for a tubing rotator. The prime candidate use case is for a vertical well with some deviation. These conditions typically cause tubing wear.

Evolution tubing rotator systems do offer benefits in slant well operations too. In these situations, our E-Plus Tubing Rotators work best. This is because the hanger system in the E-Plus is built with bushings that distribute the load stress evenly in the casing bowl.

In the horizontal applications where the pump is landed after the kick in the horizontal section, our rotators are not suitable.

Our tubing rotators will work on wells using Progressive Cavity Pumps (PC Pumps/Screw Pumps) and with Beam Pumps (Pump jack/Sucker Rod Pump).

m Type Depth into the Box

There are potential issues as well depth increases, especially with deviation.

We have a variety of options per style of rotator. The common wellhead options are: 7" x 2000# and 7" x 3000#

Wellheads common to South America are

  • 7" x 3000#

Wellheads common around Heavy Oil area and southern Alberta are:
  • 7" x 2000#
  • 7" x 3000#

Wellheads common to Northern Alberta and Northern British Columbia are:

  • 9" x 2000#
  • 9" x 3000#

We also produce 9” and 11” in pressure ratings of 2000#, 3000#, and 5000#, contact us for more details.

There are many brands and different types of wellheads and hangers on the market and in the field. Currently, we stock hangers to accommodate “A” style, “CT” style, and “FMC” thermal style for our E-style rotators.
If you are unsure of what hanger you are using, please refer to the well file.

Hangers are specific to the wellhead profile for them to ensure proper well control.

There are two basic configurations:

  1. Conventional – This is a flanged configuration. There are 2 options we can supply in this configuration:

    • Bolt-through – meaning the stud must go from the bottom of the flange on the wellhead, through the rotator bonnet, and through the flange on the flowtee.

    • Studded – meaning there are twice the qty of shorter studs that will bolt from the rotator bonnet down through the wellhead flange, and then from the top of the rotator bonnet through the flange of the flowtee.

  2. Composite – This is a BOP/flowtee composition.

    The studs will come from the bottom of the composite BOP through the rotator bonnet and through the wellhead flange. The studs will only require nuts on the bottom of the wellhead flange. There will be no stud from the hole above the worm gear and the Composite BOP, and one short stud from the hole below the worm gear through the wellhead flange. This information will help us supply you with the proper stud kit.

We can supply 2 3/8, 2 7/8, and 3 1/2 with EUE connections on the hangers. Other thread types, can also be custom ordered. Contact us for more details.

We have 3 different ways to drive our rotators:

  1. Manual – this consists of simply a handle and a shear coupling. The operator would have to come out and crank the rotator roughly 15 – 20 times. It takes approx 70 cranks to completely rotate the tubing.

  2. Mechanical – this consists of a 10:1 gear box, a mounting bracket, a handle, jerk-line assembly, and a shear coupling. After the drive is mounted to the rotator, the jerk-line assembly is attached to the walking beam of the pump jack. The ratchet will work in conjunction with the stroke on the beam pump. This drive assembly will only work on rod pump applications.

  3. Electrical – this consists of a motor (12V, 110V, 460V) a 400:1 reducer with 60:1 gear box, mounting bracket, and shear coupling. Once the rotator has been mounted with the drive it will operate as soon as there is power applied to the motor. The rotator will make 2.5 complete rotations in a 24 hour period.

You don’t necessarily need a swivel or anchor to operate a tubing rotator. If the wells are shallow, operators will generally run "open hole".

There is always the availability to purchase a tubing swivel and torque anchor(No Turn Tool) with a rotator. If you intend to run a torque anchor/tension anchor, your system will require a tubing swivel.

Possible recommendations:

PC Pump

  1. Many of Evolution's Dynamic Torque Anchors, including the DTA, DTA-XB, CTA, CTA-XB and the ATA - Advanced Torque Anchor, will work with both CDHS Swivel, the Two-Way Swivel or the E-Slim Swivel Two Way.
  2. Our Halbrite Torque Anchor, and Basic No-Turn Tool will work with CDHS swivel only.
  3. Could run open hole with swivel only – a two way swivel is recommended.
NOTE Torque anchor can be run above or below the pump at the consultant/tool hand’s discretion. Swivels must be run ABOVE pump and/or torque anchor

Rod Pump
  1. Can be run open hole if it’s shallow just like the PC pump.
  2. Can be run open hole with swivel above insert pump.
  3. The most recommended operational set up would be to use a tension anchor of some sort. With a tubing rotator, the CDHS swivel in this application.
