Oil Mining in Detail.

Upon drilling oil comes out of the ground as crude oil that has to be refined through scientific processes to come up with the different components of oil that we have today. The oil formation process is pretty simple as dead organisms drop dead and sink deep into the earth they decay over millions of years and we end up having crude 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. To have oil, exploration followed by extraction has to take place and it’s all the work of oil companies. Exploration is conducted by geologists who are tasked with finding the crude oil and pinpointing the exact location where the extraction will be effected. The geologist will look for areas that will present good conditions that can 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. 3D and 4D seismic imaging can also be used in the locating of oil that is trapped in the earth’s reservoir rocks. This kind of oil exploration works by sending some shocks with some special equipment deep into the hidden rocks of the earth.

To understand the results of this kind of imaging the reflection of the waves are analyzed . 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. Identifying an area to extract oil is one thing and mining is another. The geologists embark on conducting an environment impact study and marking the perimeter boundaries 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. When all the rights and titles have been obtained the company can comfortably begin and it starts with clearing of trees and any obstructions to the area. Access roads are constructed to enable ease of moving machinery in and out of the area when needed.

Water is important and needed in the drilling process and that is why the company will first drill boreholes if there is no water nearby. The excavation process will have a lot of mud and rocks being extracted which needs to be dumped, the company has to dig pits for this disposal. A pit is dug around the main drilling area for easy access, after that actual drilling can begin.
