A Variety of Downhole Tubing Anchor Solutions
Anchor assembly at no additional charge is available for TechTAC’s standard B2 anchors and the company’s patented Slimline® TAC. Many operators and service companies have standardized on the Slimline® TAC for their downhole assemblies because it provides up to 245% more flow area than the standard B2 design.
A recent computational fluid dynamics (CFD) study found that with that increased flow area, the Slimline® creates far less pressure drop and turbulence, as fluid and gas flow around the TAC, than a traditional design. Wells that experience less pressure drop and turbulence are much less likely to encounter plugging and gas locking.
In the unlikely event that a Slimline® TAC does get stuck in a well, the anchor’s unique design allows it to be cut over in far less time than a standard B2 TAC. Due to the smaller diameter, only the slip protectors and slips need to be cut over.
One completion foreman with a U.S.-based oil and gas company saw this reduced cut over time firsthand. He said, “Some of our wells were producing a lot of sand, so the anchors were getting sanded in. Standard anchors would take several hours, and sometimes days, to cut over. The Slimline TAC is completely different. It took longer to assemble the power swivel than it did to cut over the Slimline anchor. Less than 20 minutes.”
