TechTAC secures patent for tubing anchor tech with proven downhole success
TechTAC®, a provider of tubing anchor solutions for the oil and gas industry, has secured a U.S. patent for its Slimline® QuickSet™ Tubing Anchor Catcher (TAC).
The original Slimline TAC surpasses standard B2 tubing anchors by providing up to 245% more flow-by area within the annulus of a well, helping to mitigate gas locking and boost production, TechTAC said. The newly patented Slimline QuickSet TAC gives the added benefit of requiring fewer surface rotations to set and release the anchor. Whereas a traditional mechanical tubing anchor requires 6-to-8 turns at the tool to be fully set or released, the Slimline QuickSet TAC achieves the same result in just 1-to-3 turns.
The reduced revolutions required to set the Slimline QuickSet TAC allows petroleum engineers and operators more flexibility in the design and deployment of their downhole production strings. Its patented mechanics makes the Slimline QuickSet TAC a viable option when anchoring tubing strings deep; in the curve of a horizontal well; or where the deviation survey indicates high dog-leg severity or cork-screwed wellbore geometry.
Use in the field
Many production companies have shared recent positive experiences using the Slimline QuickSet TAC as part of their downhole assemblies.
“Despite trying a variety of different products, we could not get a tubing anchor to set in the dogleg of one of our horizontal wells," said one petroleum engineer operating in the Permian basin. "After hearing about the Slimline QuickSet TAC, we decided to give it a try – and we were able to fully set the anchor in the bend of the well.”
“The deviation in one of our wells made it impossible to get enough torque with our surface tools to fully set a traditional anchor," added a petroleum engineer operating in the Bakken. "We decided to try a Slimline QuickSet TAC instead of the usual quarter-turn anchor. Not only did the Slimline fully set, but it was a fraction of the cost of the alternative.”
