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. 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.
Oil drilling companies are very important as without them we would not be where we are today . 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. To find oil is determined by the geologist pinpointing areas that have god conditions that could 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 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. 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. 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 also dig pits for disposing mud and the rocks during the excavation process. 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.
