Oil Rigs and How They Work

Oil Rigs and How They Work


Have you ever wondered how oil is being pumped out from the ground? Or, how oil companies locate these oils in the first place? You may have seen in the movies black crude oil spurting out of the ground, pumping out freely from the ground to the top. However, oil production in the modern day that we live in today, is very different from what you can see in the films.

How is oil formed?

Oil can be found in many areas around the world, and Australia is one of the countries that is abundant with oil. Drilling rigs Australia is a huge and significant industry for many years now. Oil is a fossil fuel that is formed from the remains of plants and animals. Many of these fossils were organisms called plankton that died some 10 million to 600 million years ago in the ancient seas. These dead organisms then sank down into the seabed and the mud that is located at the bottom of the sea. With little to no oxygen present, they decay in layers over the decades.

The remains become carbon-rich compounds, forming an organic layer later on, which is a mixture of sediments made out of fine-grained rock and shale. Over the years, heat and pressure helped in the distillation of this compound into its current form today, which is a natural gas and crude oil.

This oil then flows and further accumulated into a more porous and thicker substance in a form of sandstone and limestone sipping deep within the earth’s crust. This is called the reservoir rock. Natural movements within the earth aided in trapping this natural oil within the rocks in between the layers of the earth’s crust called cap rock, which is comprised of marble or granite.

Oil Drilling

An oil company selects a certain area for drilling. Geologists then survey the area to determine the quantity and quality of the oil in the reservoir. Environmental studies will be conducted if necessary. Trees or shrubs in the area will be cleared off and the land will be leveled. Roads will also be built for accessibility. Water is essential in drilling, so there must be a source of water nearby. If the area does not have a natural source of water, then a water well will have to be made. A reserve pit will also be dug to be used as an area where heavy rocks and drilling mug will be disposed. All throughout the process of drilling, this pot will be used. The hole will be lined with plastic for environmental safety.

An oil drilling rig system comprises of many distinct components that together can make oil drilling possible. The power system of the drill rig system is made up of huge diesel engines, mechanical structures, electrical generators, hoisting systems, a turntable, and a rotating equipment. The diesel fuel oil are burnt by the diesel engines, which provides the main source of power. Powered by the diesel engine, the generators provide electrical power to the workers. The drilling process will continue as long as there is abundance of oil.
