The DTA‐XB Dynamic Torque Anchor has been developed to provide extra bypass between the casing and torque anchor. The extra bypass will allow for unrestricted flow and will avoid sand bridging around the tool.

The DTA‐XB uses wedge shaped anchoring blocks which bite into the casing was when right hand torque is generated in the tubing string. These anchoring blocks are spring loaded so that transfer of torque to the casing is immediate (clockwise). The design of the anchoring blocks requires, only a simple engaging and disengaging procedure.

The running procedure of the DTA‐XB is as simple as the design itself. The anchor installed below the pump and can be run in and out of the well freely. When the anchor has reached the required depth, the application of approximately 300 ft‐lbs (400 NM). 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 the initial setting torque.



Operation

The anchor should be run into the first joint of casting for an initial function test. This is accomplished by setting the anchor with 300 ft.‐lbs. of right‐hand torque to ensure proper engagement with the casing in the well. Once this function test is completed the torque may be relaxed and the anchor run to it’s required setting depth.

When the anchor has reached the required depth, apply approximately 300 ft.‐lbs. (400 NM) of right hand torque to securely engage the anchoring blocks to the casing wall. Pre‐torquing the tubing string will avoid engaging disengaging the anchor when starting and stopping the pump.

The setting torque may now be locked and the pump operation started.
