The no-go ring “PPK” is installed in a union joint of tubing whilst running in a new string or performing workover operations on the well. The PPK ring is an oilfield equipment and is designed to protect downhole pumping equipment of oil producing wells from the fall (drop) of scraper devices used for dewaxing the tubing string from paraffin and ashphaltene deposits during a wire or cable conveyed tripping in and out of the well.
Technical Specifications
- The depth of the ring installation is selected depending on the depth of scraping and targeted depth intervals of well testing and logging jobs
- If bore hole of the ring exceeds the diameter of the run logging tools, then a well may be easily logged to intervals deeper than the no-go ring set point
- In most cases, it is recommended to install the ring on the tubing pipe at an estimated depth of about 1000 m from the wellhead
- A deeper installation of the ring is not recommended, because on the winch drum during fishing operations, there may not be enough wire length to run the collet catcher, as well as due to the difficulty of engaging a fish/lost tool at a greater depth
