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. 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 are very important as without them we would not be where we are today . 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. The geologist will look for areas that will present good conditions that can trap oil. Oil flow will be influenced by gravity, if the geologist can ,measure the direction in which gravity changes, they could tell which way the oil is flowing. 3D and 4D seismic imaging can also be used in the locating of oil in the reservoir rocks of the earth. This kind of oil exploration works by sending some shocks with some special equipment deep into the hidden rocks of the earth.
Reflections of the waves are sent back to the surface of the earth and then they 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. With the rights obtained the company begins the mining by clearing the area of any vegetation that may be obstructing movement. To move machinery easily the company starts by coming up with some access roads to the area to move machines with ease.
Water is needed for the drilling process and if there is no water nearby the company will first drill boreholes. Disposal of the rock and mud from the drilling is necessary and that is why the company will dig pits prior for the dumping. Around the main drilling hole, a pit will be dug to allow access to the main drilling area and finally the drilling can be done.
