Proven Fuel Reserves
Proven fuel reserves shift dramatically with technology and market swings
9 hours ago
0
Why do proven fuel reserves change over time despite the physical amount of fossil fuels underground remaining constant?
Because the physical amount of fossil fuels underground is constantly increasing due to natural processes.
Because advances in technology and changes in economic conditions affect the recoverability and profitability of extracting these fuels.
Because proven reserves include all fossil fuels discovered, regardless of extraction feasibility or cost.

Natural Gas
The invisible gas warming our planet is masked by a harmless scent
9 days ago
0
Why does natural gas contribute significantly to climate change despite burning cleaner than coal?
Because burning natural gas produces more carbon dioxide than coal.
Because natural gas is odorless and therefore cannot be detected when leaked.
Because methane, its main component, is a potent greenhouse gas that leaks during extraction and use.

0
What is a key reason fossil fuels are considered non-renewable resources?
They are made from synthetic chemicals created by humans.
They are renewable because they come from plants and animals that grow quickly.
They form over millions of years through geological processes and cannot be replenished quickly.

What is the main environmental trade-off associated with natural gas use?
It produces no greenhouse gases when burned, making it completely clean.
It emits less carbon dioxide than coal but leaks methane, a more potent greenhouse gas.
Natural gas leaks are harmless because methane is not a greenhouse gas.

Natural Gas Condensate
Natural gas condensate forms when invisible gases turn into valuable liquids beneath the earth's surface
8 Feb 2026
0
What causes natural gas condensate to form during natural gas extraction?
The natural gas is exposed to high temperatures, causing it to vaporize completely.
The temperature drops below the hydrocarbon dew point at a set pressure, causing some gases to condense into liquids.
Natural gas condensate forms only when the gas is mixed with water underground.

Methane in natural gas is odorless but a rotten egg smell is added for safety
5 Feb 2026
0
Why is an odorant added to natural gas used in homes and industries?
Because natural gas is naturally odorless, an odorant is added to detect leaks easily.
To improve the energy content of natural gas by adding sulfur compounds.
Because natural gas naturally smells like rotten eggs and the odorant enhances this smell.
