Everyone in his daily life are in contact with objects that depend on oil or natural gas on their making. For example In order for you are car to run it must be filled with oil, Most of you use gas for cooking.
Have you ever asked yourself where do this oil and natural gas come from?
Without using technical words, the article explains how oil and natural gas are formed with three easy steps. If a reader lack prior knowledge of oil and gas industry, do not worry the article uses simple language in order to give you a better understanding.
Note: Oil and natural gas are related products often found in tandem, so their process of formation is similar
Okay let’s see how oil and natural gas formed
Stage 1 – All of the oil and gas we use today began as microscopic plants and animals living in the ocean millions of years ago.. In the shallow water where these animals lived, sweep current comes on and pushes these animals down where there is not sufficient oxygen to live and so they die.
Over millions of years, these layers of sands and animals are burned and covered by more layers until the first layer get very deep.
Stage 2 – as they became buried ever deeper, heat and pressure began to rise. The amount of pressure and the degree of heat, along with the type of biomass, determined if the material became oil or natural gas.
In an area where more shallow and organic materials were buried in a short time we get heavy oil
In area where organic materials were buried very deep over 2,000 meters for long time we get only we get lighter oil
If organic materials buried more than 6, 000 meter deep and for a long time we get only natural gas
Stage 3 – after oil and natural gas was formed. They tended to migrate through microscopic pores in the surrounding rock.
Some oil and natural gas migrated all the way to the surface and ran away. Other oil and natural gas deposits migrated until they were caught under impermeable layers of rock or clay where they were trapped.
These trapped deposits are the reason why we find oil and natural gas today.
