Watch the former global artificial lift advisor for BP, Bruce Friesen, break down the results of a new computational fluid dynamics (CFD) report that compares the performance of two different types of tubing anchor catchers: TechTAC’s patented Slimline® TAC and a standard Baker B2-style anchor.
Among several findings, the report notes that the net pressure drop around a standard Baker B2-style tubing anchor, as fluid and gas passes through the annular cavity around the anchor, is more than double the pressure drop around TechTAC’s Slimline® TAC. A significant pressure drop, like that around the standard anchor, is the primary issue causing gas locking in rod pumps and a major contributor in the formation of scale, iron sulfide, and paraffin.
