Know the Process of Oil Formation

In 2008 alone, the United States brings in 9.8 million barrels per day and produces about 4.9 million barrels of crude oil per day. This oil will be refined into kerosene, heating oil, gasoline, and other products.

To sustain our needs, oil companies must frequently seek new bases of petroleum, as well as increase production of existing wells. If you are interested in investing in oil and gas companies, you can click

How does a company go about searching and pumping oil out of the ground? You may have seen pictures of black crude oil pouring out of the ground. But modern oil production is very different from the way it is portrayed in the movies.

The oil comes from the leftovers of small plants and animals (plankton) dead in ancient seas between 10 million and 600 million years ago. Once the organisms die, they sink into the sand and mud on the seabed.

Over the years, organisms decompose in the sediment layer. In this vein, there is little or no oxygen present. So microbes broke the remnants into carbon-rich composites that form an organic layer.

The organic material is mixed with sediments, forming a fine-grained shale, or source rock. As the newly deposited sediment layers, they do intense pressure and heat on the host rock.
