Describe hydraulic fracturing (“fracking”) for the recovery of natural gas. Include how it’s done and the environmental benefits and drawbacks to fracking.

Expert Solution

Hydraulic fracturing or “fracking,” is a process that involves injecting water, sand, and chemicals under high pressure into a bedrock formation via the well. This process is done to form fractures in the rock as well as increase the size, extent, and connectivity of existing fractures. Hydraulic fracturing is used commonly in low-permeability rocks like tight sandstone, shale, and some coal beds to increase oil and/or gas flow to a well from petroleum-bearing rock formations. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants hold the fractures open.

The advantages of hydraulic fracturing are less carbon emission, boom in economy and increasing employment.

The various drawbacks of hydraulic fracturing are risks of groundwater contamination, air pollution, noise pollution, and the triggering of earthquakes, along with the hazards to public health and the environment.

Hydraulic fracturing (fracking) is a technique that extracts oil and natural gas from underground by injecting pressurized liquids to create fractures in bedrock formations. In recent (pre-COVID) years, the fracking industry has experienced a boom in the United States and worldwide (in China, Australia, UK). Supporters argue that fracking leads to economy-wide benefits by increasing the supply of natural gas and thus lowering gas prices (by almost 50% from 2000 to 2010). This has led to economy-wide benefits for energy...

Physical Sciences. Hydraulic fracturing, or fracking, is a method used to extract natural gas from deep shale deposits. This process involves over 500 chemicals and millions of gallons of water. In a random sample of fracking wells, the mean depth was 8000 feet. Assume the standard deviation is 440 feet and the distribution of depths is approximately normal. (a) What proportion (±±0.01) of wells have depths between 7120 and 8880 feet? (b) What proportion (±±0.0001) of wells have depths less...

sixty four percent of U.S. adults oppose hydraulic fracturing (fracking) as a means of increasing the production of natural gas and oil in the United States. You randomly select six U.S. adults. Find the probability that the number of U.S. adults who oppose fracking as a means of increasing the production of natural gas and oil in the United States is (a) exactly three, (b) less than four, and (c) at least three.

According to a Gallup poll, fifty-one percent of US adults oppose hydraulic fracturing (fracking) as a means of increasing the production of natural gas and oil in the USA. You randomly select eight US adults. Find the probability that the number that oppose fracking for this purpose is Exactly two Less than five At least three

A large portion of US oil production comes from hydraulic fracturing (fracking). Production from fracked wells quickly declines, requiring constant drilling of new wells and installation of associated pipelines to keep production at current high levels. Assume that the Trump Administration carries out the threat to levy steep tariffs on imported steel. Companies that supply pipe to the oil industry for wells and pipelines see steep price increases for steel and have to raise their prices. Fill in the table...

Explain how fracking has reduced the cost of natural gas will affect the incentives for firms to invest in research into new renewable energy technologies if renewable electricity is a substitute for natural gas and coal electricity but is more expensive than either coal or natural gas right now.

3. Natural gas is a mixture of hydrocarbons and recent developments in directional drilling and hydraulic stimulation has seen that the majority of natural gas is now produced from shale gases. These gases may contain higher proportions of higher alkanes. In order for these gases to be used via the pipeline, they must meet certain pipeline quality standards. These standards are even stricter when the natural gas is to be used by natural gas vehicles. Suppose natural gas from a...

It’s September 2015 and Apache is about to acquire a natural gas reserve at a price which translates to $1.75 per thousand cubic feet of reserves. It wants to establish a costless collar for January 2016 sales of 500B cubic feet of natural gas, using January put and call options. One option contract is for 10,000 mmBtus, where mmBtu denotes 1 million British thermal units. Puts with a strike of $2.85/mmBtu have a premium of $0.168/mmBtu, while calls with a...
