Golden Rules for Planning a Well Kill

1) Obtain relevant well and reservoir data.

2) Decide on the best method to kill the well.

3) Determine the kill fluid density appropriate
to the formation pressure to kill the well.

4) Generate a kill graph.

5) If possible, simulate the well kill.

6) Generate a well kill procedure identifying
fluid, equipment, and personnel
requirements, expected pressures, and
safety requirements (barriers).

Golden Rules When Performing a Well Kill

1) Conduct an awareness and safety meeting
for all personnel involved.

2) Prepare the well.

3) Pressure test all surface equipment.

4) Check fluid density and volume.

5) Commence operations as per the kill
procedure.
If Reverse Circulation is used:

• equalise over circulation device
• increase pump rate slowly to the rate.
• surface choke must be adjusted to regulate the THP.
• returns to be monitored.
• pump the appropriate volume of kill fluid.

6) Check that the well is “dead”.
