Well Control Quiz: Kick Warning Signs - Part2 -

1. How can the Driller prevent swabbing? Choose two answers

a- Increase the viscosity of the drilling fluid
b- Pull the drill pipe fast
c- Pull the drill pipe slowly
d- Pump a slug
e- Pump out of the hole

2. If connection gas is detected, what action should be taken?

a- Flow check
b- Directly shut in the well
c- Ask the Supervisor.

3. After a round trip, the driller circulate bottom up. The mud logger noticed gases in the shale shaker area. What is the cause of this?

a- Trip gas
b- Connection gas
c- Background gas

4. You are tripping into the hole and have broken circulation. The measured gas percentage in the drilling fluid suddenly increases from 10% to 23%, before decreasing back to 10%. What type of gas is this?

a- Background gas
b- Connection gas
c- Shallow gas
d- Trip gas

5. While drilling, gas levels increased in the return flow from 8% to 9%. Which type of gas is this?

a- Trip gas
b- Connection gas
c- Background gas

6. What should be done if the shaker man / Derrick Man noticed an increase in the cutting size and the shaker is over flowing?

a- Contact the supervisor.
b- Inform the driller to perform flow check.(as this is a warning sign)
c- Open the Shaker bypass.
d- Change screen

7. While drilling, the cuttings returning to the shakers become bigger and splintered. What should you do?

a- Communicate the kick warning sign to the Supervisor.
b- Communicate the situation to the Mud Engineer.
c- Instruct the Derrickman to change the shaker screens.
d- Instruct the Shaker Hand to by-pass the shale shakers.

8. While drilling, the shape of the cuttings on the shaker changes and there is significant increase in gas percentage; while there is no increase in mud pits. What should the supervisor should do with the driller?

a- Stop drilling and perform a flow check
b- Continue drilling
c- Increase Mud density.

9. What is the best practice from the well control point of view while RIH with casing

a- Flow check every 10 joints
b- Calculate the trip sheet using closed end displacement.
c- Monitor the closed end displacement returning on the active system.
d- Use self-filing float valve, monitor that the open end displacement is returning on trip tank

10. After connection and while circulating bottom up circulation, it was observed that the return flow increase. How do you explain this?

a- Blow out
b- Connection gas
c- Swabbed Kick

11. Trip drill takes time to be done while POOH and RIH. Why trip drill should be done?

a- To make trips faster
b- To POOH pipes more than rig hoisting capacity
c- To train crew to shut in the well with safety valve.
d- To increase ROP

12. According to API, which of the following statements is true regarding a well control drill?

a- A well control drill should be announced
b- A well control drill Should be scheduled after drilling casing shoe
c- A well control drill Should be scheduled with the crew change
d- A well control drill should not be announced, so no one is aware about the time of the drill.
