Question 1 of 15

The principle of buoyancy explains why oil and gas tend to migrate upward through water and porous rock. The buoyant force acting on an object ________.

A. Equals the weight of the fluid displaced by the object

B. Equals the volume of the fluid displaced by the object

Question 2 of 15

How does injecting water into an oil well increase the amount of oil that can be recovered?

A. The injected water dissolves oil that was too thick to flow previously.

B. The injected water floats more oil towards the top of the formation.

C. The injected water forces more oil towards the bottom of the formation.

D. The injected water and oil react chemically to increase gas pressure in the formation.

Question 3 of 15

How does pumping steam into an oil well increase the amount of oil that can be recovered?

A. The steam warms the oil and reduces its viscosity.

B. The steam forces more oil towards the bottom of the formation.

C. The steam reacts chemically with the oil and reduces its viscosity.

D. The steam increases the reservoir pressure.
