Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the exploration tools?Seismic surveys (2D, 3D, 4D), well logs, basin modeling, geochemistry, remote sensing
2. How do oil and gas form from rocks?Organic-rich rocks like marine shales get buried, heated, and turned into oil and gas through chemical reactions.
3. Why do we need traps for oil and gas?Traps are special rock shapes that stop the oil and gas from moving away, so they stay in one place where we can find them.

Source Rock: Sedimentary rock containing sufficient organic matter to generate hydrocarbons.
Reservoir: Porous and permeable rock formation capable of storing and yielding hydrocarbons.
Cap Rock: Impermeable rock layer overlying a reservoir, preventing hydrocarbon escape.
Basin Modeling: Computer simulation of geological processes to predict hydrocarbon generation and accumulation.
