What to Check Before Running an Anchor Downhole

Shawn Dickerson | March 8, 2024

When a TechTAC Authorized Dealer receives an assembled anchor, the accompanying packing slip includes several notes. One of them reads: “Tools are to be checked upon delivery to ensure they are in correct working order.” But what does it mean to “check” the anchor? While individual circumstances may vary, this post will highlight a few key items that should be inspected before running an anchor downhole.

A Focus on Quality

Assembling a Slimline TAC

One of TechTAC’s core values is to always meet the highest standards of quality. Whenever a tubing anchor leaves one of our facilities – whether a patented Slimline® TAC or a standard B2 anchor – dealers can trust that product has been built according to key quality standards. Those standards include using American-made steel and following a best practice assembly procedure.

Before Running an Anchor Downhole

However, once the anchor leaves a TechTAC® facility, it can encounter conditions that may damage or otherwise prevent the tool from being ready to run in a well. Unexpectedly harsh road conditions during shipping are one example. Others could be how the anchor is unloaded or how it is stored. Even the dedicated team at TechTAC® is still human and may occasionally miss doublechecking the tightness of an anchor sub. For those reasons, performing a few simple checks before the anchor leaves a service company’s shop is important:

  • Tighten Subs to Customer Requirements –When the TechTAC team assembles an anchor, the top and bottom subs are firmly tightened to industry standards. However, every customer is different and may have higher or lower torque recommendations. With that in mind, anchor subs should always be checked and tightened to specific customer requirements.
  • Cycle the Anchor – To ensure proper actuation of the slips when the anchor is downhole, it’s important to cycle each TAC before it’s delivered to a well. That means manually turning the body to verify the slips fully extend. With the Slimline® and B2 anchors, the TAC is usually fully set in 6-to-8 turns. With the Slimline® QuickSet™, 1-to-3 turns are typically required.
  • Tighten Exterior Bolts and Screws – In addition to tightening subs and cycling the anchor, it’s best practice to also tighten any exterior screws.

Ensuring Optimal Anchor Operation

Most of the time, these checks won’t reveal any issues. But establishing a consistent quality assurance process for every anchor can minimize the risk of future challenges. To learn more about ways to optimize the performance of TechTAC® anchors, check out the product resources page.
