Among the most dangerous industries in the world is the oil mining. Nevertheless, the need to use oil and natural grows each day, and therefore mining of oil becomes essential. Since energy is critical in our daily life, this makes petroleum products which are from fossil fuels become the most crucial its located deep within the ground. These fossil fuels are as a result of dead ancient animals and plants which have decomposed in time to form these valuable products. To acquire the fossils, therefore, calls for it to be mined. Initially, to achieve this was quite difficult because the methods used were not reliable. Nowadays there is an advancement in tech and equipment such as satellite imaging has made it easier to locate and mine these reservoirs accurately.
These fossils once located by the geologist using some specialised scientific equipment. They begin the work of mining to extract the reservoirs which are deep within the crust of the earth. The process may involve the geologist working for an oil company or entirely on their own. Drilling is done to locate the oil reservoir trapped in the rock sediments. They begin by shallow digging to get the information on the terrain so that separating the oil bed is made more accessible. The drills used are known as jack-up rigs, and they a can be set up at 200 feet deep. When they get 2000 feet, they are fitted with bags of air in a process called offshore drilling. This is in most cases used while drilling at sea. More info can about the drilling process can be obtained from the page: https://www.tumblr.com/blog/jacobjasondemedici
When mining on the sea, the process involves mounting the drills on the ships so that they can be able to extract at a depth which may be up to 8000 feet. The enormous drills amazingly do mine at these depths under the sea while mounted on the ships. This method, however, is discouraged by most oil companies because it may endanger the aquatic life or pollute the sea. This is because numerous toxins may arise from the mining process which can be difficult to control.
Once the material is obtained, they are usually in crude for which need to be refined. They are taken through the refinery process, and various products are purchased which can be utilised by the human in their day to day lives. They include diesel, petrol, bitumen, liquefied petroleum gas among others. Countries with these deposits are considered to be productive as oil is one of the most product that is consumed globally.
