1 Pay attention to fire prevention and prepare fire extinguishers;
2 Calculate how much the density drops after mixing the oil, and pay attention to the increase;
3 Prepare the emulsifier to prevent the crude oil from not emulsifying in the drilling fluid;
4 Control the mixing speed, preferably in several cycles, slowly and evenly mixed;
5 carefully check whether the BOP is flexible and easy to use.
