Volumetric Method

Math quiz helps us to increase our knowledge

1 / 10

Use the scenario below to answer the following question:

Gas kick taken and well closed.
SIDPP = 0 psi (solid float)
SICP = 400 psi

Gas migration is increasing wellbore pressures.
Circulation is not possible.

The volumetric method will be used to offset the effects of the gas migration.

SICP = 400 psi
Working pressure = 100 psi
Mud Weight = 10 ppg
Drill Pipe capacity = 0.01776 bblf/ft
Drill Pipe x Casing capacity = 0.0489 bblf/ft

Use the information above to calculate the volume of mud that should be bled off throught the choke per step:

2 / 10

The well has been shut-in on a kick and the kill operation has not started.

SIDPP = 500 psi
SICP = 700 psi

After stabilization, both pressures begin to increase due to gas migration. If the drill pipe pressure is kept constant at 700 psi, what will happen to bottom hole pressure?

3 / 10

Which of the following statements best describe the Volumetric Method?

4 / 10

The well has been shut-in on a kick and the kill operation has not started.

SIDPP = 500 psi
SICP = 700 psi

After stabilization, both pressures begin to increase due to gas migration. If the casing pressure is kept constant at 700 psi, what will happen to bottom hole pressure?

5 / 10

The well is closed on a kick.
SIDPP = 500 psi
SICP = 700 psi
Both pressures are rising due to gas migration. If the drill pipe pressure is held constant at 500 psi, what will happen to the bottom hole pressure (BHP)?

6 / 10

A gas kick is swabbed-in while pulling out of the hole and, after stabilization, the kick is migrating. Once circulation is not possible at the moment, what well control method can be used to offset the gas migration?

7 / 10

Slow pump pressure = 400 psi at 40 SPM
The well is shut-in on a kick.
SIDPP = 500 and SICP = 800
Before starting to circulate the kick out, there is a pump failure. Assuming there is no float valve in the drill string, what surface pressure should be kept constant in order to compensate the effects of the gas migration and maintain the correct bottom hole pressure?

8 / 10

Use the scenario below to answer the following question:

The well has been shut-in on a kick.
SIDPP = 400 psi
SICP = 900 psi

Gas is migrating while waiting to start the kill operation. If the casing pressure is kept constant, what will happen to the bottom hole pressure?

9 / 10

Use the scenario below to answer the following question:

The well has been shut-in on a kick.
SIDPP = 500 psi
SICP = 800 psi

Gas is migrating while waiting to start the kill operation. If the drill pipe pressure is kept constant, what will happen to the bottom hole pressure?

10 / 10

Use the scenario below to answer the following question:

Gas kick taken and well closed.
SIDPP = 0 psi (solid float)
SICP = 500 psi

Gas migration is increasing wellbore pressures.
Circulation is not possible.

The volumetric method will be used to offset the effects of the gas migration.

SICP = 500 psi
Working pressure = 150 psi
Mud Weight = 11 ppg
Drill Pipe capacity = 0.01776 bblf/ft
Drill Pipe x Casing capacity = 0.0489 bblf/ft

Use the information above to calculate the volume of mud that should be bled off throught the choke per step:
