Well Control Quiz: Kick Warning Signs - Part 3 -

1. The crew must be prepared to act quickly and effectively if there is an influx. What is one action the crew can take in advance to minimize the volume of a potential influx?

a- Build drilling fluid volume in the active tank.
b- Continue well operations while the Pit Volume Totalizer (PVT) is offline for maintenance.
c- Run regular drills to ensure that the crew is competent.
d- Store the Drill Pipe Safety Valve (DPSV) and the crossovers in the heavy tool store.

2. Why do you conduct a trip drill when running in the hole?

a- To determine how long it will take to shut in the well.
b- To give you time to check the pipe tally and hole fill volume.
c- To give you time to safety grease the travelling block from a riding belt.
d- To provide the drill crew with training if there is a kick while tripping.

3. Which action helps to prevent swabbing?

a- Installing a Non Return Valve (NRV) in the drill string.
b- Monitoring trip tank levels.
c- Pumping a heavy slug before pulling out of the running in the hole,
d- Pumping out of the hole.

4. After a connection, the active pit level does not return to the same volume level as before the connection. What could this indicate?

a- Air was pumped into the well during the connection
b- The drilling fluid in the annulus is over loaded with cuttings
c- The vacuum degasser was left running during the connection
d- There was an influx during the connection

5. On a trip out of hole, you are about to pull non-shearable BHA components through the BOP. Before continuing, what procedures must you follow? Choose two answers 

a- Confirm that the crew and the rig have the ability to follow the non-shearable shut in procedure
b- Do a flow check before non-shearable components enter the BOP
c- Function test the BOP and do a tripping well control drill
d- Have a crew tool box meeting, so that the crew pulls the non-shearable quickly
e- Secure the well before inspecting and re-testing the shear rams

6. During well operations, the drilling fluid becomes gas-cut. What is the impact on the operation?

a- This is a kick warning sign, and using the vacuum degasser may complicate pit volume measurements
b- This is a warning sign, and the well must be flow checked
c- This is a positive kick indicator, the well must be shut in before notifying the supervisor, and well pressures must be recorded
d- This is normal, and will not affect ongoing operations

7. During well operations, the drilling fluid becomes gas-cut. What action should be taken?

a- Divert the fluid to the waste mud pit, and continue the operation.
b- Notify the Supervisor and turn on the vacuum degasser.
c- Shut in the well, notify the Supervisor and record the well pressures.
d- Stop operations, flow check the well, and notify the Supervisor.

8. What is the positive indicator that the well is flowing?

a- A decrease in pump pressure
b- An increase in flow returns
c- An increase in gas-cut drilling fluid
d- An increase in torque

9. The flow sensor shows a total loss of returns and the mud level cannot be seen in the annulus. What immediate action should be taken?

a- Shut the well in and pump lost circulation material.
b- Fill the annulus with water (or lightest mud available) and record volume.
c- Pump at reduced rate adding lost circulation material.
d- Continue drilling ahead cautiously.

10. What is the main role of the Driller in preventing well control incidents?

a- Taking actions to always keep the hole full.
b- Taking actions to prevent abnormal pressures.
c- Taking actions to prevent gas cut mud.
d- Taking actions to prevent lost circulation.

11. What should the Driller do after seeing a drilling break?

a- Circulate bottoms up.
b- Flow check the well.
c- Increase the pump speed.
d- Reduce the weight on the bit.

12. What should the Driller do when kick warning signs are seen? 

a- Alert the Tool Pusher and request assistance.
b- Be alert to shut the well in quickly
c- Check for flow
d- Shut the well in.
