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).
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
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.
There are two basic configurations:
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:
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.
