The Evolution CTA-XB - Centralizing Dynamic Torque Anchor® provides a simple and reliable solution for tubing back-off when progressing cavity pumps are used.  With the trend towards larger pumps being used for production Evolution has advanced its Torquing Anchors to handle the increased vibration caused by these pumps.

The CTA-XB’s function in horizontal wells has also been significantly advanced with a  unique patented design that allows for easy running and retrieval in a variety of downhole conditions including: deep wells, horizontal wells and heavy oil situations.

The CTA-XB addresses the need for extra bypass required with large volume pumps and horizontal or deviated wells.  This allows for greaterr flow area and helps avoid sand bridging around the tool.

The CTA-XB uses the wedge shaped spring-loaded anchor blocks which engage with the casing wall when right hand torque is generated in the tubing string.  Transfer of torque to the casing is immediate (clockwise) and the tubing string may be freely rotated to the left (counter clockwise).  In deviated wells, the centralizing blocks will prevent premature wear of the anchoring blocks during running in and out of the well.

During the pumping operation, the centralizing blocks will attenuate the vibrations generated by the pump and provide a soft contact between pump and casing.  Due to the original design of the anchoring blocks, only a simple engaging and disengaging procedure is required.

Running Procedure

The running procedure of the CTA-XB is as simple as the design itself. The anchor is installed below the pump and can be run iand out of the well freely. When the anchor has reached the required depth, the application of approximately 300ft-lbs right hand torque, will securely engage the anchoring blocks to the casing wall. The setting torque may now be locked in and the pump operation started.

To disengage the anchor, simply stop the pump operation and relax initial setting torque.

 

Redressing

The tool life of the Dynamic Torque Anchor® can be extended with the use of Evolution's CTA Redress Kits.  A properly redressed tool can last the life of the well, and beyond.
