Answer 2

Answer:

1. ,An oil well is a boring in the Earth that is designed to bring petroleum oil hydrocarbons to the surface. Usually some natural gas is released as associated petroleum gas along with the oil. A well that is designed to produce only gas may be termed a gas well.

2. They constructed because we need crude oil which we cannot get without drilling the oil wells. Petroleum is extracted out by drilling holes (oil wells) into the earth's crust. ... After the pressure subsides the oils are pumped out of the wells and then sent to refining units.

3. Natural gas is often praised as a clean energy alternative. It burns more cleanly than other fossil fuels, emitting lower levels of harmful emissions such as carbon monoxide, carbon dioxide and nitrous oxides. It produces less greenhouse gases than other fossil fuels do.
