SharkTAC Tubing Anchor Casing-Scraper
A fully engineered tubing anchor that eliminates limitations of existing tubing anchors. The SharkTAC Tubing Anchor Casing-Scraper is a high-performance downhole tubing anchor that offers the greatest possible annular flowby cross sectional area – more than a tubing coupling and is no longer the production limiting component in the annular flow path above a downhole pump.
It is very common for annular flow-by restrictive tubing anchors to cause erratic pump fillage and reduce downhole gas separator performance. An annular flow path restriction above a pump also prevents annular fluid levels from being pumped down or pumped off (limiting a well’s production potential). See technical paper: McCoy, J., Rowlan, L., Taylor, C., Podio, A. (2014), “Tubing Anchors Can Reduce Production Rates and Pump Fillage”, URTEC-1918491.
The “catcher” feature common with standard tubing has been limiting both the annular flowby area and the internal diameter of tubing anchors. As such, a catcher feature has been engineered out from this design to avoid such limitations.
