The design of the Slimline® Tubing Anchor Catcher allows sediment and formation gas to flow around the anchor instead of creating a choke.
In wells with sucker-rod pumps, tubing anchor catchers, or TACs, can stabilize the production string. That stability creates higher pump efficiency and minimizes wear on rods, tubing, casing and the rod pump.
However, in addition to the benefits, standard B2-style TACs, along with other traditional anchor designs, are also susceptible to several common problems that can hinder production.
Because the annular area between the TAC and well casing is so small, sediment and scale can bridge-off on top of the anchor and cement it in place, often resulting in an expensive fishing job. At the same time, the TAC essentially acts as a choke, trapping formation gas below the anchor, leading to a gas locked rod pump.
