All about the Oil Mining Process.
Oil has different compounds which have different areas of application, before those compounds can be refined from oil it has to be extracted in crude form and subjected through some scientific processes. Over millions of years, dead organisms sink deep into the earth and decompose forming the oil. When the plates deep into the earth starts experiencing some movements and shifting the gas and oil do that as well, it gets trapped in what is referred as reservoir rocks.
Oil drilling companies have contributed to making the world what it is today, without them the energy industry wouldn’t be as we know it. They are responsible for the exploration and also the extracting of this precious resource from the earth. Geologists are the professionals that are entrusted with the finding of oil, this is the exploration part. To find oil is determined by the geologist pinpointing areas that have god conditions that could trap oil. The gravitational change in the earth’s crust will change from time to time and that needs to be observed by the geologists as it could indicate the direction in which the oil flows. If gravity is not the way to go , 3D and 4D seismic imaging can be used to locate the oil that is in the reservoir rocks . This imaging is capable of sending shocks into the hidden rocks deep into the earth.
The reflections of the waves are then sent back to the surface of the earth where the geologist will then analyze them to have some results. When the results of the exploration has revealed that a there are oil deposits that are worth mining , the area is marked with buoys if located under a water body and if on land the coordinates are marked. When an area has been identified , extraction does not begin right away. The geologists will conduct and present reports of environment impact and they will mark the perimeter of the area as well. A company will only start to mine when they have been awarded the rights by the authorities in charge of the area with the deposits. If the company has been awarded the rights, it will start by clearing trees and any obstruction of movement to the area. Access roads aid in moving of machinery easily into the area and that’s why the company will embark on making the roads first.
Water is needed for the drilling process, is there is no water on site then the company has to drill a borehole. The company will dig pits for the dumping of rocks and mud that comes out from the drilling process. Drilling can begin as soon as a pit is made around the main drilling hole to enable access to the area.
