| 4. | Description | Abstract | The article presents the known technological causes of the overflow of the water-gas mixture and reservoir fluid in the behind-the-casing space of a cemented oil and gas well and through a cement plug, and the complications to which they can lead. Continuous work to improve well abandonment technology allowed Wellbore Integrity Solutions to create a highly efficient ProMILL™ system in 2016. The ProMILL system combines a Bridge Plug assembly, a Section Mill, and a high-ratio Underreamer to prepare the foundation for a cement barrier in a single run. During the milling and expansion process, it eradicates all leak paths from the cement fill, while achieving continuous, reliable rock-to-rock zonal isolation. Was presented the results of the successful execution of the First ProMILL Job in Kazakhstan onshore - successful deployment of the 5500 ProMILL for high-grade section milling and outer casing ID scraping in one trip. |
