Crude oil is an extremely lucrative commodity, as gasoline is highly in demand throughout the world. It is made from the fossil remains of plants and animals that perished millions of years ago. As the remains sink into the bottom of the sea and start to decompose, layers of sedimentary mud compress them. The decomposed remains will then undergo a chemical process, which converts them into crude oil as well as natural gas. This natural oil and gas are then trapped between rock layers by natural movements and phenomenon within the earth.


Drilling Oil

Oil companies are a very significant part of the industry because of the effort they put in to access and extract this valuable resource, which is energy. Drilling oil is an extremely expensive and complex process. Thus, marketing oil as an energy source is a great business with remarkable profits.

To locate crude oil, you would need the expertise of a geologist. These professionals search the regions that have perfect conditions to trap oil. Geologists are able to measure even the slightest changes in the Earth’s gravitational field. They use this information to determine the flow of oil.

A handful of methods are used to locate oil and gas and one is by using 3D and 4D seismic imaging. It creates shock waves that can penetrate through hidden rock layers. It sends back reflection to the surface where geologists measure and analyze it.

Once an oil trap determined is a prospective supply that could yield substantial profit, the area will be marked. If the drilling site is on land, the position coordinates will be marked by GPS. Buoys will be used to mark the site if it’s over a body of water. When everything is set, drilling can commence.


The Process

Before the oil company starts drilling, they need to acquire permit and drilling rights from the government first. The geologists will have to survey the area and conduct an environmental impact study. If there is no threat to the environment, the company will then set up the drilling platform and equipment. Drilling rigs in Australia are very useful for this industry, making it possible to bore thousands of meters beneath the earth.

If the site is land-based, the preparation for extraction includes clearing of trees and other obstructions. They will build access roads to allow the easy movement of machinery. Drilling would need some water, so water wells will be dug if there is no water supply nearby. If the area is offshore, a platform will be set-up and anchored on the site.

The workers will also need to have reserve pits for the disposal of rock shavings and the mud dug during the drilling, which are later enclosed in plastic to prevent any environmental contamination. When all is set, the drilling rig can start boring and extracting.
