permeability

Question 1

This averaging method is used
to determine the average
permeability of layered-parallel
beds with different
permeabilities.

Answer 1

Arithmetic Average

Question 2

This averaging method is used
to determine the average
permeability of series beds with
different permeabilities.

Answer 2

Harmonic Average

Question 3

This averaging method is used to determine the average
permeability of random flow with different permeabilities.

Answer 3

Geometric Average

Question 4

Factors Affecting Effective & Relative
Permeabilities

Answer 4

Rock wettability
* Fluid saturation history (i.e.,
imbibition or drainage)

Question 5

is a fluid flow process in which the saturation of the
nonwetting phase increases and the wetting phase saturation decreases.
(e.g., waterflood of an oil reservoir that is oil-wet).

Answer 5

drainage

Question 6

is a fluid flow process in which the saturation of the
wetting phase increases and the nonwetting phase saturation decreases.
(e.g., waterflood of an oil reservoir that is water-wet)

Answer 6

imbibition

Question 7

At low pressures, the measured permeability is higher than actual. This is
due to gas slippage and referred to as

Answer 7

Klinkenberg effect.
