PETE FINAL 1010 THURBER EXAM
QUESTIONS AND ANSWERS GRADED A+
2025/2026
High oil prices - ANS Winners: oil-producing nations, oil and gas companies, energy investors;
Losers: oil-importing countries, consumers, energy-intensive industries, and governments facing
budget strain.
Low oil prices - ANS Winners: oil-importing countries, consumers, energy-intensive
industries, and governments facing budget strain; Losers: oil-producing nations, oil and gas
companies, energy investors.
Drilling engineers - ANS Manage technical aspects of drilling exploratory, production, and
injection wells.
Well-log analyst (petro-physicist) - ANS Evaluates the well to determine the ability of the
borehole to produce petroleum.
Production engineers - ANS Include subsurface engineers, manage the interface between the
reservoir and the well, including perforations, sand control, and downhole monitoring
equipment; evaluate artificial lift methods; and select surface equipment that separates the
produced fluids (water, oil, and natural gas).
Reservoir engineers - ANS Work to optimize the production of oil and gas via proper well
placement, production rates, and enhanced oil recovery techniques.

, Consumption - ANS Oil demand: the amount of oil the world uses in a given time period.
Production - ANS Oil supply: the amount of oil the world produces in a given time period.
Inventories - ANS The amount of oil in stock tanks that is not needed for current supply and
demand.
Spare production capacity - ANS Oil from wells that are already drilled but not producing.
Geopolitical risks - ANS The price of oil and gas might increase or decrease depending on the
tensions between countries.
Market variables - ANS Future market trading activities, commodity investments, exchange
rates, equity markets.
Porosity - ANS Equation: Vp/Vb or pore volume/Bulk volume.
Inter-granular porosity - ANS Porosity between grains.
Intra-granular porosity - ANS Porosity within grains.
Packing - ANS The size of sand grains does not affect porosity, although the range of
variations of sand grains does.
Shape - ANS 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.
