Coal, Natural Gas and Oil Are All Fossil Fuels

Algae and plants flourished in freshwater waters millions of years ago.The organic material combined with other sediments and was deposited after decaying and falling to the seafloor. The traces of these species evolved over millions of years under high pressure and high temperature into what we now know as fossil fuels. Coal, natural gas and petroleum are all fossil fuels produced undersimilar co-generation. Today petroleum is found in vast underground reservoirs where there were ancient seas. Petroleum reservoirs can be found under the ground, or under the ocean.

They refine their crude oil using huge drilling devices. Petroleum is used for making gasoline, which is an important product in our daily lives. We release toxic emissions and high amounts of carbon dioxide, a greenhouse gas, as petroleum products such as oil are burned for electricity. Carbon helps regulate the Earth’s atmospheric temperature, and it adversely affects our climate by adding fossil fuels to the natural balance.

Under the surface of Earth, and in tar pits, there are huge quantities of petroleum found bubbling to the surface.

Even the deepest wells that are developed to extract petroleum exist far below. Petroleum, like coal and natural gas, is nevertheless a non-renewable energy source. It has taken millions of years to develop, and when it is processed and ingested there is no way we will substitute it

Oil is categorized by three main categories: its geographic location, its sulfur content, and its API gravity (a density measure): All over the world, geography oil is mined.

Nevertheless, there are three main crude oil markets that set standards for rating and pricing certain oil supplies: Brent Crude, West Texas Intermediate and Dubai Petroleum bubbles down to the Earth’s surface in some places. For example, porous rock in parts of Saudi Arabia and Iraq allows oil to seep into small ponds to the surface. Some crude remains trapped in deep oil tanks, though.

The overall petroleum content in a reservoir is considered oil-in-place. Most oil-in-place gas products that make up an oil-in-place reserve can not be removed. Such Petroleum liquids can be too heavy, too risky or too costly to dig.

The portion that can be produced and processed from oil-in-place of a reservoir is the oil reserves of that reservoir. Often the decision to invest in complex drilling operations is made on the basis of proven oil reserves from a site.

Drilling can be either directional, exploratory or developmental.

Exploratory exploration is also exploring where there are no established deposits. Exploratory exploration, also known as ‘wildcat,’ is a risky business with a very high rate of failure. The potential rewards of finding oil nevertheless attract other ‘wildcatters’ to seek exploratory drilling. For starters, ‘Diamond’ Glenn McCarthy is recognized as the ‘King of the Wildcatters’ for his success in finding oil. Directional drilling requires drilling vertically to an established oil field, then veering the drill bit at an angle for additional resources to be reached. Directional drilling claims related to the 1991 Gulf War. Iraq suspected Kuwait of using methods of directional drilling to extract oil from Iraqi oil deposits along the Kuwaiti frontier.

Most modern wells use an air rotary drilling rig, which can operate 24 hours a day. In this process, engines power a drill bit. A drill bit is a cutting tool used to create a circular hole. The drill bits used in air rotary drilling rigs are hollow steel, with tungsten rods used to cut the rock. Petroleum drill bits can be 36 centimeters (14 inches) in diameter.

As the drill bit rotates and cuts through the earth, small pieces of rock are chipped off. A powerful flow of air is pumped down the center of the hollow drill, and comes out through the bottom of the drill bit. The air then rushes back toward the surface, carrying with it tiny chunks of rock. Geologists on site can study these pieces of pulverized rock to determine the different rock strata the drill encounters.

When the drill enters rock, some of the oil would naturally come up from the ground, going from a high pressure environment to low pressure. The immediate release of oil can be a ‘gusher,’ one of the most spectacular mining operations, firing hundreds of meters into the air. It is also one of the most severe, and a piece of equipment called a preventer for blowouts. To extract oil, pumps are used. Some oil rigs are equipped with two pump sets: mud pumps and extraction pumps. ‘Mud’ is the boring agent used to make the oil and natural gas mining boreholes. Drilling oil circulates through mud pumps.

The petroleum industry requires a wide range of pumps for production. What pump to use depends on the quality, geography, For instance, they are dipped directly into the fluid. A gas pump, also known as a bubble pump, uses compressed air to force the petroleum to or from the surface. One of the most common exhaust pump styles is the pumpjack, the upper part of a piston pump. For their guided, frequent dipping action, pumpjacks are nicknamed ‘thirsty birds,’ or ‘nodding donkeys.’ A crank carries up and down the large, hammer-shaped pumpjack. Far below the water, the pumpjack’s action pushes a hollow piston up and down, bringing fuel continuously or well back to the surface.

Offshore drilling is way more expensive than onshore drilling. It usually employs the same onshore drilling techniques, but requires a massive structure that can sustain the tremendous strength of ocean waves in stormy seas. Offshore drilling facilities are some of the world’s most large manmade structures. These often include living quarters for people working on the bridge, as well as docking facilities for transport employees and a helicopter landing pad. Oil platforms will wreak huge environmental disasters.

Drilling equipment problems can cause the oil to spill out of the well and into the ocean. It is extremely difficult, costly and painful to fix the well hundreds of meters beneath the ocean. Millions of barrels of oil will spill over into the ocean before plugging into the well. When oil spills into the ocean it floats on the water and causes disaster to the animal population. One of the most devastating effects of this is on birds. Petroleum kills feather waterproofing capabilities, so birds are not protected from cold ocean water. Hypothermia will kill thousands. Oil spills also endanger fish and marine mammals. The base can either be attached to the ocean floor and float, or it can be a solid framework set to the bottom of the bay, shore, or ocean.
