I write to express my interest in pursuing a PhD degree in hydraulic fracturing in the department of Mineral and Resource Engineering, DDD University. I am excited about the opportunities that abound for a research work in unconventional hydrocarbon reservoirs and the impact of such work in enhancing optimal development and hydrocarbon recovery. I discussed my interests with Dr. John Doe, who has also obliged to serve as my supervisor should I be admitted into the doctorate program.
The role of shale oil, shale gas, tight oil and tight gas reservoirs, generally classified as unconventional reservoirs, in meeting with the ever-increasing energy demand has come under serious considerations in recent times. While significant successes have

I also took courses in Engineering Mathematics and passed these courses with distinctions.
In my quest to gain deeper knowledge about hydrocarbon reservoirs, I took up a trainee engineer position at Delta/Terratek Limited, a core analysis company in Nigeria, after completing my undergraduate studies. I learnt how to use gas porosimeter and permeameter to determine porosity and permeability of rock samples which are key parameters that influence production and recovery of hydrocarbons from the reservoirs. I was able to analysis these data, combine such with petrophysical and lithological description of slabbed core samples to characterize reservoirs. I analyzed X-ray images of core samples to identify natural fracture structures within the reservoir core samples as well as carried out particle size analysis on ditch cuttings samples of some oil reservoirs. My work in the laboratory helped me to better understand the reservoir pore systems, and I intend adapting these experiences to further my studies in enhancing recovery from unconventional hydrocarbon plays.
I am currently, a Master of Engineering student in Petroleum Engineering at Dalhousie University, with a project focused on oil recovery from oilsands by cavitation process. I am looking at the effect of particle size on oil ablation from sand particles while samples of oilsand slurry are
Shale is found in many colors but those that are very dark or black contain oil and gas. Conventional drillers look for pools of oil and gas above shale rock. “The oil and natural gas migrated out of the shale and upwards through the sediment mass because of their low density. The oil and gas were often trapped within the pore spaces of an overlying rock unit such as sandstone. These types of oil and gas deposits are known as "conventional reservoirs" because the fluids can easily flow through the pores of the rock and into the extraction well”. (Geology.com King) Conventional drilling into shale has declined because those conventional supplies are disappearing and drilling companies have known this for quite some time. They also know that more oil and gas can be extracted. Geology.com’s Hobart King provides this insight. “Although drilling can extract large amounts of oil and natural gas from the reservoir rock, much of it remains trapped within the shale. This oil and gas is very difficult to remove because it is trapped within tiny pore spaces or adsorbed onto clay mineral particles that make-up the shale. In the late 1990s natural gas drilling companies developed new methods for liberating oil and natural gas that is trapped within the tiny pore spaces of shale. This discovery was significant because it unlocked some of the largest natural gas deposits in the world” (King Geology.com). The site goes on to provide this outlook for fracking oil

The global crisis surrounding energy needs grows in severity as time goes by and in order to solve it, scientists have created the innovative solution known as hydraulic fracturing (Source 5). Hydraulic fracturing, commonly referred to as “fracking,” is a process that injects water, chemicals, sand, and other materials into layers of shale. The injected mixture cracks the layers of shale, releasing trapped natural gasses that can be collected (Source 1). Fracking occurs deep under the surface of the earth, miles below the groundwater that is accessed from drinking-water wells. In the mid-2000s, “fuel prices were rising rapidly” (Source 5). Hydraulic fracturing was a cheap solution that not only brought the world out of a state of emergency but made oil prices drop. The new method of gas collection grew the oil and gas industry, benefiting people all around the world. Fracking is a cheap, effective solution to global needs, but is under attack from skeptics who worry about environmental hazards. The claims against fracking not only have no real evidence but also risk destroying the jobs in the oil and gas industry as well as support for energy needs. Hydraulic fracturing is not only a cheap but a safe method that supports global needs surrounding both energy and jobs.
The practice of Hydraulic fracturing, or releasing a mixture of water, sand, and various chemicals into wells dug beneath the earth to unlock its natural gas has become a very controversial issue (Earthworks ). For some, the practice means new forms of energy in the U.S. and thousands of new jobs. While others have pointed to the connections between the release of chemicals into the environment and the contamination of water supplies. Other studies have linked this new technology to air pollutants and an increase in earthquakes due to disturbances in the earth’s shell. All of these issues and concerns point to a need for further regulations to diminish these negative effects on the environment.
This paper explores the hydraulic fracturing process, exactly what it is, what the fracturing process does to the earth and the surrounding environment in addition, to the consequences. Hydraulic fracturing is fracturing of rock by pressurization. This process by which oil and natural gas can be forced from the earth. The hydraulic fracturing process takes millions of gallons of clean water, sand, chemicals and pumps them underground at high pressure to break apart rock to release gas and or oil. My research has led me to the discovery that there are as many proponents for fracking as that are those that oppose the process. One thing
Hydraulic fracturing is an increasingly common practice used to access otherwise unobtainable oil or natural gas reserves. While it shows promise as both a valuable economic resource as well as a source of energy independence, many oppose the practice due to alleged environmental dangers. In order to foster a greater understanding of the issues at hand, the following topics are discussed: what hydraulic fracturing is, how it is performed, and where it is located in the United States and abroad; how it has benefited the United States’ economy and how it can support the United States’ energy needs; legal and environmental issues; domestic and overseas regulations; and last but not least, what President Obama had to say about the practice in his 2012 Executive Order. The paper concludes with the author’s personal opinion regarding regulation of the practice here in the United States.
Hydraulic fracturing in combination with advancement in directional drilling has made it possible to economically extract oil and gas from unconventional resources. The growth in U.S. oil and gas exploration and production made possible by the increase in use of hydraulic fracturing, has raised concerns about its potential to impact human health and the environment. Concerns have been raised by the public about the effects of hydraulic fracturing on quality and quantity of drinking water resources. The hydraulic fracturing water cycle includes five main activities: the withdrawal of ground or surface water needed for hydraulic fracturing fluids; the mixing of water, chemicals, and proppant on the well pad to create the hydraulic fracturing fluid; the injection of hydraulic fracturing fluids into the well to fracture the formation, the return of injected fluid and water produced from the formation to the surface; and the reuse, treatment and disposal of wastewater generated at the well pad, including produced water (U.S. EPA, 2015). With the water cycle being so massive and prolonged, the presence of potential negative impacts is greatly increased.
The process of hydraulic fracturing – shooting water, sand, and chemicals at high pressure into underground wells to release natural gas – is a divisive issue: Some say it dumps chemicals into ground water supplies, others argue it causes earthquakes, and still others think it can revolutionize America’s energy industry.
The purpose of this research is to analyze the impacts, both social and economic of hydraulic fracturing in the United States. This has been a heated issue with environmentalists and surrounding community members concerned over the environmental and health related problems associated with this practice while providing substantial economic benefits.
As we become increasingly technologically complex, humans are becoming more and more reliant on energy. This energy is used for gasoline, heating and electricity among many others. Acquiring energy is very important but acquiring this energy in the most environmentally friendly way is even more important. There are various methods used when obtaining natural gas but one of the most controversial ways is through the process of hydraulic fracturing. The idea of Hydraulic fracturing or Fracking dates back to 1866 when inventor Col. E.A.L. Roberts lowered a torpedo to the bottom of a well, filled the well with water and the detonated the charge. The weight of the water forced an explosion and oil began to gush out. Modern
In 2000, shale beds where the number one source of America’s constant need for gas. Most of that production increase has come about to the growing need of hydraulic fracturing, also known as “fracking”, which is a process used to release oil or gas from underground formations that are otherwise too hard to mine with other tools. Over the past few years, advances in fracking technology have made huge reserves of natural gas in America economically recoverable. According to the Energy Information Administration, shale gas plays, or fields, in the United States, most notably the Marcellus, in Pennsylvania, West Virginia, and New York, and the Barnett, in Texas, are said to contain enough natural gas to give power to the country for a hundred and ten years. With the everlasting specter of energy independence, some have argued that such efforts to recover natural gas need to be expanded. Activists concerned with fracking’s potential environmental hazards view the new process as a serious threat to our environment. There are many different opinions on wether or not fracking is a safe way to gain our gasoline, and to meet the growing demands of gasoline around the world. The process of fracking creates cracks that come from wells into oil and gas formations by pumping highly pressurized fluids, ceramic beads, sand, and a mixture of chemicals, into the gas formation. As this fluid holds the underground fissures open, oil and gas fly up the well to the surface where they are
In order to comply with the goal to cut traditional fossil fuel consumption by 2050, the UK needs to turn to alternative types of energy. Fracking is a method of extracting shale gas from deep within the earth’s surface, by injecting large quantities of water at very high pressures. This water is mixed with chemicals, in order to free the gas by breaking down the shale within sedimentary rocks (Goodwin 2014). These rocks are impermeable, the gas cannot flow through it, and so it needs extracting via fracking. Currently
Hydraulic Fracturing is controversial process. Yet due to the rising need for energy around the world, it seems that fracking will be around for quite some time. The problem is that because the process has only been widely used in the last decade, there have not been very many long-term health studies done about the potentially hazardous effects of the process on humans and the environment. As time progresses, there might be increased awareness about the phenomena. The problem is by the time the effects will be known, it might already be too late.
As the spring semester of my senior year of high school began, I still wasn 't sure what I wanted to study when I began college in the fall. I always had been a good problem-solver, and I was fairly certain I wanted to study engineering, but I didn 't know which discipline interested me the most. As my high school graduation date loomed closer, I began to get anxious about not having chosen a major. My parents, both having worked in the oil and gas industry in parts of their careers, encouraged me to give petroleum engineering a shot, so I did. That summer, I attended the LSU geology field camp for freshmen in Colorado Springs, Colo., for six weeks. During that time, I took basic geology courses and learned to appreciate the effect lithology has on oil and gas. I am thankful to have attended this camp, because when August rolled around, I was confident in my choice of majors.
