PETE 1010 Exam Actual Questions
and Answers 2026
Porosity -
correct answer ✅The percentage of the total volume of a rock or
sediment that consists of open spaces. Vp/Vb
Inter-granular porosity -
correct answer ✅porosity between grains
Intra-granular porosity -
correct answer ✅porosity within grains
Cementation -
correct answer ✅mineral crystals that have grown around the
sediment grains & bonded them together.
Packing -
correct answer ✅the size of the sand grains do not affect porosity:
however, the range of variations of sand grains affect porosity.
Shape -
correct answer ✅if sand grains within a reservoir are elongated or
flat and are packed with their flat surfaces together then porosity

might be low compared to a reservoir with spherical-shaped sand
grains.
Deposition -
correct answer ✅arrangement in which grains were laid down and
compacted, amount of clay or other material that cements the sand
grains together.
Permeability -
correct answer ✅A rock is permeable when its pores are
connected, so that fluids can flow through it by moving from one
pore to another pore.
Effective Porosity -
correct answer ✅The interconnected pore volume or void space in
a rock that contributes to fluid flow or permeability in a reservoir.
Effective porosity excludes isolated pores and pore volume
occupied by water adsorbed on clay minerals or other grains. Total
porosity is the total void space in the rock whether or not it
contributes to fluid flow. Effective porosity is typically less than total
porosity.
