When mining oil, we first get raw form of the energy source that has to be refined into many compounds that each find some application in life today. Over millions of years, dead organisms sink deep into the earth and decompose forming the oil. The earth experiences some movement under the plates and in result the movements trap oil and natural gas between the reservoir 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. They are tasked with finding areas that have good conditions that ,would trap oil. Gravilty could pin point the direction in which the oil is flowing for this reason the geologist needs to observe and measure the changes that occur in the earth’s gravity. 3D and 4D seismic imaging can also be used in the locating of oil in the reservoir rocks of the earth. This kind of imaging works by sending some shocks deep into the crust of 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. If the area is found to have potentially lucrative deposits of oil, the coordinates of the area are marked so that extraction of oil can begin, if the area is over water body it is marked with a buoys 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. The oil company will proceed to get the rights that allows them to break ground and start mining. With the rights obtained the company begins the mining by clearing the area of any vegetation that may be obstructing movement. 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 important and needed in the drilling process and that is why the company will first drill boreholes if there is no water nearby. The company will also dig pits for disposing mud and the rocks during the excavation process. Drilling can begin as soon as a pit is made around the main drilling hole to enable access to the area.
