Natural gas occurs in fine pores of some rocks. Depth, at which natural gas is located, varies from 1000 meters to several kilometers. Gas is extracted from the subsurface using specially drilled wells called producing or operating wells. In fact, there are many types of wells , and they are used not only for extraction, but also for studying the geological structure of the subsurface, prospecting for new fields, supporting operation, etc. The oil and gas extraction industry can be classified into four major processes. • Exploration, • Well development, • Production, • Site abandonment. Exploration involves the search for rock formations associated with oil or natural gas deposits, and involves geophysical prospecting and/or exploratory drilling. Well development occurs after exploration has located an economically recoverable field and involves the construction of one or more wells from the beginning (called spudding) to either abandonment if no hydrocarbon are found or to well completion if hydrocarbons are found in sufficient quantities. Production is the process of extracting the hydrocarbons and separating the mixture of liquid hydrocarbons, gas, water, and solids, removing the constituents that are non-saleable, and selling the liquid hydrocarbons and gas. Production sites often handle crude oil from more than one well. Oil is nearly always processed at a refinery; natural gas may be processed to remove impurities either in the field or at a natural gas processing plant. Finally, site abandonment involves plugging the well(s) and restoring the site when a recently-drilled well lacks the potential to produce economic quantities of oil or gas, or when a production well is no longer economically viable.

How would you like to see a repeat of the devastating event that took place in the Gulf of Mexico? If we were allowed to drill in the refuge all that it would take is for another malfunction like that and the environment of that refuge would be damaged for years. “Most important of all are the more than 130,000 caribou of the Porcupine herd…, these caribou are at the heart of environmentalists’ case against drilling” (McCarthy). The reason that these specific animals are the reason for not drilling is that the caribou migrate to the plains, where the drilling would ...
In 1908, the U.S. Geological Survey (USGS) predicted that the total future supply of U.S. oil would not exceed 23 billion barrels. In 1914, the U.S. Bureau of Mines predicted that only 5.7 billion barrels of oil remained. In 1920, the USGS proclaimed the peak in U.S. oil production was almost reached. In 1939, the Department of Interior declared that there was only 13 years of oil production remaining. In 1977, President Jimmy Carter claimed, “We are now running out of oil.” Despite these predictions, the U.S. has produced over 200 billion barrels of oil since the early 1900’s. (The Futurist, 1997)
Gas in shale formations are“low in permeability,” making it very tedious to extract, but with the increase in technological knowledge in fracking and horizontally drilling into shale beds, the vast reserves of natural gas resource could be extracted (4). Fracking is a large industrial operation that boost the “productivity of a oil or gas well” (5). It is a process by which, under very high pressure, a mixture of water, chemicals, and sand, are pumped into shale formations that causes fractures in the rocks to open wider or create new fractures that would allow otherwise trapped oil and gas to flow into the wells (6).
Current drilling technology was unable to penetrate the thick rock of southwest Texas and oilmen could only extract the surface layers of oil, unable to tap the vast resources that lay far below. Big Howard came up with the idea for a rolling bit, with 166 cutting edges and invented a method to keep the bit lubricated as it tore away at the rock. Later that year, Big Howard produced a model and went into business with his leasing partner, Walter B. Sharp, forming the Sharp-Hughes Tool Company. Rather than sell the bits to oil drillers, Hughes and Sharp decided to lease the bits out on a job basis, for the tidy sum of $30,000 per well. With no competitor able to duplicate this new technology, Sharp- Hughes Tool possessed a profitable monopoly over oil extraction. So quickly was the invention successful that in late 1908, the partners built a factory on a seventy-acr...
...gy can successfully replace oil. Just as oil will not run out overnight, its replacement will be equally gradual. The success of this transition is largely contingent on time management. Presently, there is no nation privy to a miracle solution. A bulk of available alternative energy sources are not self sufficient, and require oil to jump start their production. Solar panels, while a step in the right direction, are built in factories, shipped in trucks, flown in planes dependent on oil. Oil needs to be conserved, reserved solely for uses that will benefit future generations, such as creating green energy products. As long as there exists a shadow of a doubt as to the inevitability of peak oil, the existence of debate serves not only as an obstacle, but as a cause for hope. When everyone is forced to acknowledge the peak oil issue, it may very well be too late.
Increased production: According to GAO, the U.S. and Canadian crude oil production have increased, resulting in lower costs of crude oil for some refiners.( United States Government Accountability Office , 2014). It observed that after significant decline in decades, monthly U.S. crude oil production increased over 55 percent compared with average production in 2008 ( United States Government Accountability Office , 2014).
Drilling for oil has many benefits, but it can also cause many problems. There is no clear answer to the question on offshore drilling, because both sides have strong arguments. Because we are so dependent on oil, we need to get it from somewhere, and economically speaking, offshore drilling makes more sense. However, we also need to take the environment into consideration. This is why I strongly believe should utilize the precautionary principle and analyze the possible consequences on the environment before starting any new drilling sites. What also needs to happen is for people to become less dependent on oil, by developing alternative fuel sources and using more sustainable transportation methods.
In 1982, the federal government put the billions of dollars in some research institutions of this field. During the 1980s, Federal government passed energy act, which provides tax incentives or other preferential policies for the energy industry. In 1986, with several private gas companies, the energy department of United States successfully built the first air drilling technology shale gas horizontal well. In the 80s and 90s, the federal government act further by 29th of unconventional gas tax incentives to encourage...
Hydraulic fracturing, or fracking, is the process of extracting natural gas from deep in the ground. This method requires a company, usually an oil company, to drill deep into the earth’s crust and into the beds of shale, and then drill horizontally. Water, along with sand and other toxic chemicals, are then pumped into the shale rock to fracture it and letting all the natural gas that is trapped in the rock to flow up to the surface where most of it can be collected (McGlynn 1055).
For example, Hydrofracking; What is hydrofracking? Gas industries use hydrofracking to extract natural gases from shale ground in order to power Americans homes. When gas industries hydrofrack, they dig ten-thousand feet into the mantle of the earth and turn perpendicular to the t into shale layers with cement and steel casing to prevent leaks. Then rupture the layer of sediment with high pressures of water, sand and a plethora of chemicals. Once the chemicals are saturated in the crevices of the drill site, they extract the excess fluid and then ship them to market.
Fracking has become a highly controversial and publicized topic due to rising concerns and growing analysis into the mutual benefits of hydraulic fracturing to retrieve natural gas and oil reserves. With concerns of water pollution, mismanagement of toxic waste and irreversible

Many explorations are limited due to not being able to bring enough fuel. It is the hope of many companies to use asteroids like gas stations, refueling so missions can continue
Many answers can come from exploring space. Getting a “few lumps of moon rock” can answer so many questions we asked ourselves for millennia. Can we truly belong in a place we do not know about? Space exploration will better us now and in the future for several reasons. The idea of travelling into the unknown has puzzled life since it could move.
The oil refinery converts crude oil into valuable products and supplies. These products are made and sent to many countries abroad, in which are transported on land or along rivers and canals. Crude oil is then arranged and categorized into segments by fractional distillation. Raw crude oil, or unprocessed crude oil, is not normally beneficial in most industrial applications. Low sulfur crude oil has been valuable as a burner fuel to construct steam for the force of seagoing vessels. The lighter elements have the ability to construct explosive and dangerous vapors in the gas tanks. There are extremely hazardous, and are often used in war ships. The remaining hydrocarbon molecules are filtered from crude oil and used towards lubricants, feedstock, plastics, and fuels.
