Reservoir Rock Mechanics Quiz

What is the definition of porosity in reservoir rock mechanics?

• The density of the rock grains

• The fraction of void space in a rock to its bulk volume

• The weight of the rock sample in air

• The volume of displaced mercury in a sample

Which type of porosity only considers interconnected pores in a rock?

• Effective porosity

• Isolated porosity

• Total porosity

• Induced porosity

How can porosity be indirectly measured using Boyle's Law?

• By measuring the volume of displaced mercury

• By saturating the sample with liquid

• By balancing weights of dry and saturated samples

• By calculating the grains volume of the core sample

What influences porosity in reservoir rock mechanics?

• All of the above

• Arrangement and shape of the grains

• Amount of cementing material

• Mixture of various shapes and sizes of the grains

Which method of porosity measurement involves saturating the sample with liquid?

• Volume of displaced mercury

• Average porosity calculation

• Grains volume by using Boyle's Law

• Direct measurement of pore volume

What is the average porosity calculation based on?

• Volume of displaced mercury

• Direct measurement of pore volume

• Grains volume by using Boyle's Law

• Combination of interconnected and isolated pores

Which term represents the fraction of pore volume occupied by water in a reservoir at maximum hydrocarbon saturation?

• Residual oil

• Irreducible water saturation

• Interstitial water

• Connate water
