Driller's Method In Well Control Procedures & Calculations
https://www.youtube.com/watch?v=oA_qbss10Po

In Driller's Method, the Kill is split into two circulations to fully control the well. 

- During the first, the Kick fluid is circulated without changing the mud weight. 
- During the second, once the Kick is out, the mud is weighted up and pumped around the well on the second circulation.
