Polycationic drilling fluids and their reusable use
The results of application of polycationic drilling mud "Katburr" in drilling conditions in the Caspian depression at the Astrakhan gas condensate field are considered. Significant advantages of using the "Catburr" mud in comparison with traditional anionic-non-ionic drilling muds are noted. Using the example of the Astrakhan gas condensate field, the problem of minimizing the utilized volumes of drilling fluid is considered. The use of polycationic drilling fluids in the field allows to prevent production, reduce drilling waste and minimize complications. To prevent the disposal of drilling fluids and reduce the environmental load on the environment, it is recommended to increase the capacity of the tank farm for their storage and reuse.
