While the unique design of the patented Slimline® TAC helps to greatly diminish the number of stuck anchors production companies have to remove, like any piece of downhole equipment, it may occasionally be necessary to cut over a Slimline® TAC.
In this video, taken from a recent Tech Talk with the Society of Petroleum Engineers, TechTAC’s Director of Product Management Luke Reary explains why the process to cut over a Slimline® TAC is faster and easier than performing a similar operation on a standard B2 anchor.
Reduce the Risk of a Stuck Anchor
While the process to cut over a Slimline® TAC is indeed easier than cutting over a standard B2 anchor, it may also be needed less frequently. The design of the Slimline® – with a reduced OD and tapered subs – allows sand and sediment to fall past the anchor instead of bridging on top of it. “Sand was a frequent problem in many of our wells,” said an engineer with a large production company operating in the Southern United States. “It would fall on top of a standard TAC and cement the anchor in place. After switching to the Slimline, that problem all but disappeared.”
Bruce Friesen, former global artificial lift advisor for BP, noted: “[There are] multiple benefits of running the TechTAC Slimline anchor. Number one, reduce pressure and temperature drop, reduce turbidity and turbulence, which all four of those things contribute and cause the formation of scale, iron sulfide, paraffin and solids. [Eliminate] all those parameters … then you don’t have plugging. You don’t have stuck anchors. You don’t have workovers. You don’t have fishing jobs.”
