Energy Crisis

The future global economy is likely to consume ever more energy, especially with the rising energy demand of developing countries such as China and India. On top of this, energy demand is expected to grow by almost half over the next two decades. The charts below shows the trends of worldwide energy consumption and the energy consumption of three big giants, USA, China and India till 2040.

At present, we rely on coal, oil and gas (the fossil fuels) for over 80% of our current energy needs – a situation which shows little sign of changing over the medium-term without drastic policy changes. The problems associated with an over reliance of non-renewable energy sources is the fear that our energy resources are starting to run out, with devastating consequences for the global economy and global quality of life. At the same time, the tremendous risk of climate change associated with the use of fossil fuels makes supplying this energy increasingly difficult.

While the potential for a crisis if we run out of energy is very real, but there is still time before that occurs. In the past two decades proven gas reserves have increased by 70% and proven oil reserves by 40%. At expected rates of demand growth we have enough for thirty years supply. Moreover, better technology means that new oil and gas fields are being discovered all the time while enhanced recovery techniques are opening up a potentially huge array of unconventional sources, including tar sands, shale gas and ultra-deep water. While in the long term, the use of renewable sources of energy like harnessing wind and solar energy is inevitable, at present the costs associated are high and the efficiency of the power generated is low to make it viable for developing countries like India and China from adopting them on a large scale.
In the short term, of all the unconventional sources of...

The Shale Gas Revolution in the U.S.

...The Shale Gas Revolution in the U.S. - Aspect of Domestic Market - Prepared for Microeconomics May 6, 2014 "The all-of-the-above energy strategy I announced a few years ago is working, and today, America is closer to energy independence than we’ve been in decades," Obama said during his fifth State of the Union speech on January 2014. In a fact sheet accompanying the speech, the White House called on Congress to establish "sustainable shale gas growth zones." As mentioned by the U.S. president Obama, “The Shale Gas Revolution” is hot topic in the energy industry recently. Previously, the U.S. has imported large amounts of natural gas from other countries, but now it is expected to be an exporter of natural gas because of shale gas production. (Reference: Annual Energy Outlook 2011, May, 2011) Exporting shale gas would bring economic benefits. Gross Domestic Product can be increased, employment on LNG supply chain would be increased, and there will be no import of LNG anymore. Nevertheless, there is some limitation which will not favor to domestic LNG market. For exporting the shale gas, there are many researches to determine the associated costs. The price U.S. LNG exporters can afford to charge can be separated into the following components. Price = Wellhead price + Pipeline + Liquefaction + Shipping + Regasification Based on the above formula, experts’ estimate that the minimum price the U.S. and afford to export LNG to Asia, mainly Japan and......

Hyrdro Fracking in Marcella Shale

...Hydrofracking in Marcellus shale: The Consequences of America’s Gas Rush Introduction Demand for fossil fuels in America has led to a flurry of unorthodox methods for the extraction of natural gas. Fracking or hydrofracking in the U.S.A has proven to be an efficient way of extracting natural gas from permeable rock. A new large scale hydrofracking operation has been proposed in the eastern states of Ohio, Pennsylvania and New York. This method of extraction is highly controversial, and is thought to have severe environmental and potential health consequences. This essay will provide further insight into the practice of Fracking in an area of shale known as Marcellus shale, and help to expose the environmental and human implications. What is Hydrofracking? Hydraulic Fracturing is an un-conventional process used in the extraction of gas in permeable rock (David 1973). A horizontal well is drilled into permeable rock such as shale and is injected with millions of gallons a high pressure fluid known as frac-fluid, this fluid is a mixture of sand, water, and an array of lubricating chemicals (Deutch 2011). The high pressure frac-fluid forces open fishers (cracks) within the rock which are kept open with sand granules; this allows pockets of gas to flow more easily from the shale (David 1973). Once the well is depleted all fluid that can be recycled is extracted, and the well is capped to stop any unused gas escaping (David 1973). The process of fracking is expensive and......

Anti-Fracking Paper

...plays in our nation’s ambitions for a clean and sustainable energy future. Due to recent technological advances in horizontal drilling techniques, the vast natural gas reserves found within the shale formations underground in the United States have become easily accessible. Responsible development of these resources is believed to be key to a sustainable financial, and environmentally prosperous future for America. However, recent environmental and health concerns beg to differ, and question whether these new developments pose more of a threat to americans than they are worth. Nature sustains life on our planet. Humans have developed an organization of society that runs on machines. What does it take to run the machines that power our world? Our society also runs on money. So anything that plays into the running of our society must must invariably be tied to how it profits the people in charge of running things. How does it benefit us as a whole? This question is larger than the debate which this paper addresses, yet it is valid in that it is an overarching theme that drives the situation behind the issues within. A big part of what our economy has deemed is important in order to sustain the current level of comfort that we have been sold is largely based on non-renewable energy sources such as oil, coal, and gas. It is a very competitive world. Our level of comfort is key to maintaining an edge over our competitors on the global financial stage. Deep within the earth,......

Gas Land Argumentative Analysis

...I viewed Gas land part one and Gas land part two about a year ago, and what I found out was both illuminating and dismaying. I had to watch the documentary twice to grasp the severity and comprehend what the energy companies were doing and how they were going about extracting the source of energy from the environment. The Impact on the environment can be catastrophic for all of the small waterways, which feed into bigger waterways, and eventually into the ocean. Amy Myers Jaffe Executive director for energy and sustainability, University of California, Davis is an advocate of drilling for natural gas or “Fracking”. She is also an expert on global energy policy, geopolitical risk, and energy and sustainability. Myers Jaffe argues that since “energy is a fundamental service for daily living”, it is necessary to search and extract new energy sources. She contends that since the United States use such a massive amount of energy, when those energy sources are used up, we cannot replace that energy with non-fossil fuels and it’s impossible to convert renewable energy into energy that can replace what is consumed by the United States. Amy contends...

The disruption of natural gas supply from the Russian Federation was particularly devastating for all countries with gas infrastructure. The region is supplied with natural gas from Russia by three different itineraries and three sub-regions are served by three different sets of gas infrastructure (see Appendix 1). Romania, Bulgaria, Greece and FYROM are supplied by a system of transit pipelines from Ukraine. Serbia and Bosnia and Herzegovina are supplied from Ukraine via Hungary, while Croatia is supplied via Austria and Slovenia. These three supply systems are not connected which in itself presents a problem. With nearly 98% gas import dependency, however, Bulgaria’s biggest issue is that all the its complete dependence on Russian gas and oil. While it is debatable, whether this......

...Earth for Clean Energy 1 Name University WGU Student ID# Deep Impact: Fracturing Planet Earth for Clean Energy 2 Shale gas has been acclaimed as the solution for a clean energy alternative. It burns cleaner than both coal and oil. There are vast quantities located in several shale formations domestically, in the United States (U.S.). Natural gas is an odorless, colorless hydrocarbon composed mostly of methane found deep in the earth in formations known as shale. In mid-1997, George Mitchell, an independent prospector made a discovery that would change the natural gas exploration industry for the twenty-first century. (Hinton, 2012). The modification of the well completion technology known as hydraulic fracturing (fracking) and horizontal drilling allowed the oil and gas industry the ability to tap into natural gas reserves trapped in shale deposits miles beneath the earths’ surface. (Hinton, 2012). Mitchell found that forcing fracking fluid at extremely high pressure into the shale formations created fissures in surrounding rock releasing the hydrocarbons and capturing them in the well head. The fracking fluid, also referred to as slick water, is made up of water, chemicals, and sand. Heywood (2012) reports that members of the energy and commerce committee of the U.S. House of Representatives said that between 2005 and 2009 the oil and gas service companies were using over 2,500 fracking products with 750 different chemicals. Some of these chemicals are......

...Dangers of Fracking Hydraulic Fracturing, also known as fracking, is a process used in nine out of 10 natural gas wells in the United States, where millions of gallons of water, sand and chemicals are pumped underground to break apart the rock and release the gas. Scientists are worried that the chemicals used in fracturing may pose a threat either underground or when waste fluids are handled and sometimes spilled on the surface. Extracting gas from shale increases the availability of this resource, but the health and environmental risks are, in my opinion, too high. Before I get rolling on the impacts of fracking, let me first present you with a little history behind it. Hydraulic fracturing of wells was first introduced in 1947 by Stanolind Oil. 1,000 gallons of naphthenic-acid and-palm-oil-thickened gasoline was injected, followed by a gel breaker, to stimulate a gas producing limestone form at 2,400 ft. Although there wasn’t a tremendous increase in production, this was a start. In 1974, Congress passed the safe drinking water act to protect underground sources of drinking water and the Environmental Protection Agency required Underground Injection Control permits under the SDWA for any injection of a fluid. The Environmental Protection Agency also banned the injection of most hazardous materials and mandated regulation for all injected materials. However, hydraulic fracturing was unhindered by these new regulations because, the same year, the Environmental Protection......

Hydraulic Fracturing

...| Hydraulic Fracturing Hydraulic fracturing is a completion process that has been proven. It allows producers to recover natural gas and oil safely. This process reduces our national carbon dioxide, reduces our reliance on foreign fuel imports, and accelerates our transition to a carbon light environment. The development of natural gas and oil is critical to America’s energy needs and economic renewal. The process of hydraulic fracturing is using water pressure under tight controls to create fractures in rock that allow oil and natural gas to escape and flow up out of the ground. While in this process “fracturing fluids” are mixed in using high pressure. This creates fissures that allow resources to move freely from rock pores where they are trapped. (Chesapeake Energy) First, the way hydraulic fracturing works is a production drill is drilled through the rock layers to intersect the coal seem that contains coal bed methane, CBN. Second, fractures are created or existing fractures are enlarged in the coal seem so that the CBM can be drawn from the well and pumped to the surface. These fractures are created or enlarged by using a thick water-based fluid which is gradually increased by rate and pressure. Third, over time the coal seam is unable to keep up with the fracturing fluid which results in high pressure causing the coal to fracture along the weaknesses within. Sand is pumped into these fractures to keep them ‘propped’ open after the pressures are released. After a...

...Solutions when Fracking to Produce Natural Gas English 215 7 December 2013 Professor Jordan Problems and Solutions when Fracking to Produce Natural Gas In light of the reality of a brutal U.S. Economy and dismal employment numbers, as well as soaring gas prices, it has never been more important than now to aggressively pursue energy independence. One way to do this is to expand fracturing. While this concept is popular in some circles, be they economists or politicians, it is not popular with all, and therein lays the challenge. Where there is challenge though there is also opportunity, and where a problem is identified, a solution must be offered. Does this concept of fracturing make sense to pursue? Yes it does, and we will explore the fracking of shale as a national policy, the challenges thereof, and look at some possible solutions that our lawmakers embrace. We will begin with a brief historical overview of the fracturing of shale. Fracturing in the United States is not exactly unknown, as hydraulic fracturing began in this country 130 years ago, making us the most “fracked” country in the world. Large scale fracking began in earnest though in the 1980s, when Mitchell Energy Development Corporation used this technology on the Barnett Shale play in Texas. What is the current status of shale fracturing? The United States in the past 130 years has produced more than 839 trillion cubic feet of gas (TCFG). Shale gas production is expected to grow 113%......

Hydraulic Fracturing

...What is Hydraulic Fracturing? Hydraulic fracturing is the process of drilling for natural gas and oil underneath the ground. Hydraulic fracturing is a procedure that can increase the flow of oil or gas from a well (what is Fracking, 2013). Hydraulic Fracturing Process  It is done by pumping liquids down a well into subsurface rock units under pressures that are high enough to fracture the rock and release the gas. The goal is to create a network of interconnected fractures that will serve as pore spaces for the movement of oil and natural gas to the well bore (King, 2013).  Hydraulic Fracturing in the United States, Europe and South America The first use of hydraulic fracturing to stimulate oil and natural gas wells in the United States was in the 1940s (King, 2013). This process used in nine out of 10 natural gas wells in the United States. In December 2012 the British government gave the approval for exploratory hydraulic fracturing to extract natural gas from shale-rock deposits (Reed, 2012). In 2011, a horizontal well with multi-stage hydraulic fracturing was completed in the Neuquén Basin of Argentina. It was the first horizontal gas shale well and the deepest shale gas well in South America (Halliburton, 2013). Economic Impact/Concern of Hydraulic Fracturing According to the Global Fund Exchange, there are a number of environmental concerns related to hydraulic fracturing. Hydraulic fracturing......

Shale Gas

...What is shale gas and why is it important? Shale gas refers to natural gas that is trapped within shale formations. Shales are fine-grained sedimentary rocks that can be rich sources of petroleum and natural gas. Over the past decade, the combination of horizontal drilling and hydraulic fracturing has allowed access to large volumes of shale gas that were previously uneconomical to produce. The production of natural gas from shale formations has rejuvenated the natural gas industry in the United States. Does the U.S. Have Abundant Shale Gas Resources? Of the natural gas consumed in the United States in 2011, about 95% was produced domestically; thus, the supply of natural gas is not as dependent on foreign producers as is the supply of crude oil, and the delivery system is less subject to interruption. The availability of large quantities of shale gas should enable the United States to consume a predominantly domestic supply of gas for many years and produce more natural gas than it consumes. An analysis in the Annual Energy Outlook 2012 (released June 2012) indicates that the uncertainty in the size and economics of the domestic shale gas resources could have a considerable impact on future domestic natural gas production and that 2035 shale gas production could be between 9.7 trillion cubic feet and 20.5 trillion cubic feet. U.S. total natural gas production is projected to range between 26.1 trillion cubic feet and 34.1 trillion cubic feet.  Where is Shale Gas Found? ...

...World Shale Gas and Shale Oil Resource Assessment   SHALE GAS AND SHALE OIL RESOURCE ASSESSMENT METHODOLOGY INTRODUCTION This report sets forth Advanced Resources’ methodology for assessing the in-place and recoverable shale gas and shale oil resources for the EIA/ARI “World Shale Gas and Shale Oil Resource Assessment.” The methodology relies on geological information and reservoir properties assembled from the technical literature and data from publically available company reports and presentations. This publically available information is augmented by internal (nonconfidential) proprietary prior work on U.S. and international shale gas and shale oil resources by Advanced Resources International. The report should be viewed as an initial step toward future, more comprehensive assessments of shale gas and shale oil resources. As additional exploration data are gathered, evaluated and incorporated, the assessments of shale oil and gas resources will become more rigorous. RESOURCE ASSESSMENT METHODOLOGY The methodology for conducting the basin- and formation-level assessments of shale gas and shale oil resources includes the following five topics: 1. Conducting preliminary geologic and reservoir characterization of shale basins and formation(s).  2. Establishing the areal extent of the major shale gas and shale oil formations.  3. Defining the prospective area for each shale gas and shale oil formation.  4. Estimating the risked shale gas and......

Hydraulic Fracking

...hydraulic fracture drilling (fracking) for gas? With the fast expansion of shale gas drilling operations and reduced federal regulations has placed our environment in harm’s way. If the environment is in trouble so are the health of humans and animals. Without proven scientific studies, the gas drilling boom sweeping the U.S. and the world will remain an uncontrolled health experiment of enormous scale. There is much controversy surrounding the impact of this type of drilling on air and water quality, placing gas and oil companies against individuals and groups concerned with environmental and health protection. It is time for federal regulation and tougher oversight control of this out of control drilling. Hydraulic Fracturing; Fracking 3 What Is Fracking Hydraulic fracturing or hydrofracking better known as fracking is a method of mining for natural gas which greatly increases the efficiency of extracting shale gas from deep underground. This method has been used since the 1940’s and perfected by Floyd Farris of the Standard Oil and Gas Corporation. In the beginning the process was simple in its technique of introducing non-explosive fluids (acids) under pressure of sand and water to cause fractures in gas shale deposits. (Montgomery & B.Smith, 2010) As this method was improved and put into commercial use, gas extraction increased by 75%.......
