Drillers Method Calculator

The Driller’s Method is a well control technique used to control the kick by first circulating out the kick fluid, then killing the well by pumping kill fluid.

The procedure for conducting the driller’s method involves the following steps:

1. Shut in the well by closing the blowout preventer (BOP) valves.

2. If a slow circulating rate pressure, PSCR, has been taken, then calculate the pressure required on the Drill Pipe for the first circulation of the well.

3. Open the choke one quarter and bring the pumps up to the kill rate.

4. As the pumps increase to the kill rate, the choke should be manipulated to maintain the shut-in casing pressure (SICP).

5. Once the pumps are at the kill rate, the choke should be manipulated to maintain the ICP calculated above.

6. Once the kick has been circulated out of the well, the first circulation is complete. The well should be shut-in again to prepare the kill fluid if it has not already been prepared.

7. The kill fluid should be pumped into the well at the kill rate. While pumping at the kill rate the choke should be manipulated to maintain the casing pressure at the shut in pressure.
