Oil Mining in Detail.
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. Crude oil does not just happen to be there, its formed by dead organisms undergoing decomposition over millions of years deep into the earth. The fact is that the earths tectonic plates are occasionally moving and shifting and this in turn has natural gas and oil trapped in some rocks.
Without the oil companies the energy industry would not be what it is today. To have oil, exploration followed by extraction has to take place and it’s all the work of oil companies. 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.
To understand the results of this kind of imaging the reflection of the waves are analyzed . The moment oil exploration reveals that there are good deposits of oil that can be extracted then the area is marked, if under water buoys are used and if on land they mark the coordinates. Oil drilling is not as simple as just starting the moment the area is located. The geologists will conduct and present reports of environment impact and they will mark the perimeter of the area as well. The oil company will not proceed to ,mine without the necessary mining rights and certifications from the authorities in charge. If the company has been awarded the rights, it will start by clearing trees and any obstruction of movement to the area. To move machinery easily the company starts by coming up with some access roads to the area to move machines with ease.
Oil drilling needs water, if there is no water nearby the company has to dig wells. The company will dig pits for the dumping of rocks and mud that comes out from the drilling process. A pit is dug around the main drilling area for easy access, after that actual drilling can begin.
