Methods of Enhanced Oil Recovery Essay example

Hydraulic fracturing is a controversial practice commonly used by oil and natural gas producers. This practice, better known as “fracking”, is used to stimulate the production of oil by fracturing shale to release natural gas. The birth modern day hydraulic fracturing began as early as the 1940s and today it is widely practiced across the United States, from new york, to Oklahoma, even all the way to California. The process of fracking is fairly simple, hydraulic fracturing (fracking) involves tapping shale and other tight-rock formations by drilling a mile or more below the surface before turning horizontal and continuing to drill several thousand feet more (Energy from Shale 2016). is drilled water is injected at an extremely high rate

In today’s society the issues of producing energy is becoming more and more scare which, constantly posses the question, “How will energy be obtained in order to sustain future generations?” Hydraulic fracturing, informally known as fracking is believed to be an effective alternative to provide us with the energy we need to fuel tomorrow. Hydraulic fracking was first used at Texas Stanolind Oil and Gas Cooperations in 1947. However, it was not until 1949 that The Halliburton Oil Well Cementing Cooperation was given a licensee to use hydraulic fracturing. Since then a combination of two advanced methods have been introduced and incorporated (4). These methods are slick-water hydraulic fracturing and precision drilling of wells. Nevertheless,

For more than sixty years, oil and gas companies have been fracturing shale rock far below the earth’s surface in order to release pockets of natural gas. The extraction of shale gas from wells dates back to 1821; but the revolutionary procedure of hydraulic fracturing—injecting pressurized fluid into shale rock to create fissures—was commercialized in the 1950s. New drilling techniques, created in the 1970s, reach previously inaccessible shale gas by allowing the use of horizontal piping within the wells. While the United States is currently dependent on foreign countries for natural resources, a hope for independence has led companies to further explore hydraulic fracturing, redefining the way that natural resources are

The process of the collection of an underground fluid would not be possible without the use of hydraulic fracturing. In the Shale reserves, located about 5,000 feet underground, suffer an extremely low permeability rate. Permeability is the measure of how well a fluid flows through an absorbent material at the depth, and within such nonporous rock, the ability of fluids to travel to the well is greatly limited. Fracturing increases the area of the fluid that is exposed to porous materials and thus greatly increases production. The method of fracturing utilizes a few key components which allow for an economical extraction of resources.

After scientists have tested the oil and the rocks, oil companies will begin drilling in the wells and rock samples will be brought to the surface. After the scientists have studied the rock samples from above ground and are convinced that they have found the right type of rock, companies begin drilling production wells. “When the wells first hit the reservoir, some of the oil begins coming to the surface immediately” (“Fossil Energy: How Fossil Fuels Were Formed,” n.d.). However, with today’s technology, oil companies are able to install special equipment to help the oil from spurting hundreds and hundreds of feet from the ground.

Hydraulic fracking is a process in which metal pipes are first drilled vertically thousands of feet deep into the ground and then further drilled horizontally in order to maximize the drilling of several wells from one drilling pad. Meaning, there is more efficiency through horizontal drilling because shale which is the horizontal layer where natural gas is found, is found at certain rock layers rather than being abundant randomly. This would defeat the purpose of constantly drilling vertically and waste money and time, therefore, the technique of horizontal drilling is efficient to the extraction process. Furthermore, this method uses millions of gallons of water and chemicals which are injected down a pipe, thus causing the shale rock layer to break. As a result, due to a difference in pressure the natural

Imagine a world less dependent on oil; a world that wars are not started over oil. This is the future the people that support hydraulic fracturing envision. The rapid development of unconventional sources of oil and natural gas using hydraulic fracturing has generated a great deal of controversy. As coal and oil struggle to remain the popular source of fossil fuel, fracking has gained a new spotlight in the war on energy. Hydraulic fracturing, also known as hydrofracking, hydrofracturing or simply, fracking, is the process of extracting natural gas from gas shales. The term gas shales refers to natural gas that is extracted from porous rocks that hold gas. A vertical well is drilled hundreds of feet into the ground, through this well, hydraulically

The Eagle Ford shale formation in south Texas has recently become the focus of many oil industry operators searching for new sources of hydrocarbons by using the latest technology in previously unexplored areas. This exploration enhances the development of even more advanced techniques as issues are identified and problems solved to address the unique properties of the formation and the surrounding surface environment. Even though a formation may be comprised of a single sedimentary layer from a similar geological time frame it is not a homogeneous block and has many features and anomalies that effect the pressure, permeability, type of hydrocarbons trapped and methods required to extract them. To understand these properties one must understand that shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay placing it in the mudstone category of rocks [1]. Shale is different from other rocks in this category because it has a fissile structure and is laminated. The black shale in the Eagle Ford formation (Fig 1.) has a special property such that it contained organic material when it was deposited and during compaction over a millennium, the organic materials were converted into trapped oil and gas hydrocarbon deposits. This oil and gas are very difficult to remove because it is trapped within tiny pore spaces and or adsorbed onto clay mineral particles that makeup the shale.

It has long been known that large amounts of natural gas reside in deep layers of sedimentary rock such as shale. However, this gas could not be extracted until recent years due to previous limitations of technology making it economically unfeasible. This is now possible due to developments in drilling technology that now allow drillers to drill horizontally. Millions of gallons of water and chemicals are then injected at extremely high pressure that fractures the rock surrounding the drill hole, allowing trapped gas to escape. This process is called hydraulic fracturing, but is known colloquially as “fracking.”

How could someone buy the and wear the perfect hat, an exceptional top, a classy jacket or coat, the most intriguing eye catching shoes but forget pants. Sounds funny but in a similar way we forget or neglect one of the most important parts of our vehicle. Oil change servicesmake, assist, and keep your car on the road. Oil lubricates your internals and keeps them from wearing out and it cools the engine by transferring heat from the working parts. To be clearer on how oil cools an engine just consider the job it does. By lubricating the parts of the motor oil reduces the friction between these constantly grinding metal parts some of which are moved by spark or combustion. When we speak of Oil change services we are speaking of those that

The oil industry in the United States is booming. However, not all oil or natural gasses are available by drilling. There are some oils and gasses trapped inside shale rock. To access these gases, a process called Hydraulic Fracturing, informally known as fracking, was invented. Hydraulic Fracking “is a controversial oil and gas extraction technique developed in the late 1940s to gain access to fossil energy deposits previously inaccessible to drilling operations. The process…literally involves the smashing of rock with millions of gallons of water- along with sand and an undisclosed assortment of chemicals in order to bring gas to the surface. (serc-carelton.edu).” This process combines water, sand, and chemicals

Hydraulic fracking industry is one of the most commonly used method to extract gas. Barbara stated that the hydraulic fracking has contribute to the U.S. economy, therefore, the industry has grown in a constant rate. For this, the use of material to produce the extraction has also grow, and also the concern for contamination. In Climate Change, Lyons mention that, scientist the climate change is not getting worse, they even wrote in “Nature Climate Change” that less contamination has occurred in the past years. Engineers have to do studies for every single step in the project; they are send to a lab and evaluate if the process should continue or if they need to verify the material again. The first step the engineers do is create the wall shale where the water will travel. The wall has a considerable shell to assure that the pressure of the water will destroy it. Glynn emphasizes, that chemicals must be added to the water in order to inject the water at high level pressure in order to penetrate the sublayers. Later, the water will create horizontal and vertical holes, then the water is extracted

The process of hydraulic fracturing has made it easier to reach gas and oil reserves that used to be impossible to access, this has led to a dramatic expansion of energy production and an increase in the activity level of the economy (Hassett and Mathur). The use of hydraulic fracturing and directional horizontal drilling are being used together to reach oil and gas that was previously unreachable with old drilling methods (Romich and Schumacher). In Ohio, there have been at least 80,000 natural gas and oil wells that have used fracking at varying depths (“Hydraulic Fracturing”). There are areas in Eastern Ohio that contain deposits of dry gas (farthest east) and wet gases and

Introduction and Background In the oil and gas industry, fracking is a major current issue that engineers are dealing with for the current state of the United states. Hydraulic fracking, or "fracking" is the process of drilling a well to the depth in the earth where shale rock is located. Once the drill bit reaches this specific depth, the drilling alters its path to a horizontal track into the shale rock in order to span the entire reservoir. Next, fracking fluid, consisting of sand, liquid chemicals, and water, is injected into the shale rock at a high pressure, which cause small cracks, known as fissures, in the rock. This action allows oil and natural gas to freely escape into the pipeline. The oil and gas mixture then flows to the surface

When steam is injected to the formation a steam chamber around the well is created [3]. The pressure of the steam should be lower than the fracture pressure of the rock mass to prevent the deflection of the rock [4]. Steam injection will go on for months during which the steam chamber expands and the viscosity of the bitumen decreases. This will cause the bitumen to flow down under gravity towards the production well. The produced oil is then pumped to the surface. Surface facilities are then used to separate the water
