Exploring involves finding the new locations for oil, which leads to the extraction and refining. Refining converts the oil into a usable form (like gas or diesel) which we use in our daily lives.
Transporting involves pipelines through which the oil is transported to oil tankers that take it to different places. Exploration might seem simple but it is rather complicated. It is not easy to explore new areas in a short duration.
There is a great demand for oil in the world market to carry out industrial, commercial and domestic tasks. This demand is more than the actual production of the oil. This is why the countries that have a lot of oil are among the richest countries.
The oil & gas industry is very important for smooth functionality of modern society. Whenever there is an increase in the prices of oil, the prices of various other products also get affected. The price of oil can be controlled if production cost of oil gets lower.
