Analysis Of Eagle Ford Shale Play

In Beaumont, Texas they had started to drill at around October 27, 1900 and before they started drilling again some of them lost hope because they had been drilling for a long time and didn't find anything. They had been drilling for over two months and drilled down above 1000 feet below the ground. When they had returned from their christmas break they started drilling and they heard a “a noise like a cannon” and natural gas was spraying out of the hole. There was so much oil that it could fill up more than 100,000 barrels a day. Texas has been impacted a lot today because they have so much oil in abundance. That is the reason why their gas prices are low and trading is

In Texas, there is an economic powerhouse that not only runs deep beneath fields of cotton, but also reaches miles beyond the green pastures of cattle. Its multitude of uses in daily life also far outweighs the benefits of technology. This resource, greater than any other in Texas, is oil. In 1866 the first commercial oil well was dug near Nacogdoches, Texas but unfortunately the well came up dry. Thirty years later in 1894 oil was discovered in Corsicana, Texas by accident while a water well was being dug. This was the first economically significant discovery of oil in Texas. On January 10, 1901, Texas was catapulted into the era of oil and gas with the discovery at Spindletop. The Spindletop well, located south of Beaumont produced roughly

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 most important of these is the Permian Basin. In the latter half of the Paleozoic era, sediments rich in organic matter accumulated here when a shallow sea got cut off from the main oceans and evaporated off, leaving lots of dead critters and evaporites. These sediments eventually got buried and compressed, causing the oil and gas to form "pockets in permeable rock, surrounded by impermeable rocks so that they couldn't escape. There the fluid sits until someone pokes a hole (well) into the area and the contents rush out as the tremendous pressure is released. Other areas of Texas with notable petroleum sources include East Texas's Woodbine Formation (formed in the Late Cretaceous), much of the Gulf Coast and the Gulf itself, and various smaller pockets in South and South Central Texas.

Hydraulic fracturing, better known as fracking, is the process of removing oil and natural gas from in between layers of shale and other low-permeability rocks. This is done by drilling both a well and a horizontal tunnel. Sand and chemicals are shot through the tunnel with incredible pressure, which cracks the shale allowing the oil and natural gas to travel up the well (Jackson, 2014). Fracking has caused a breadth of controversy due to the economic benefits and the geological consequences.

Hydraulic fracturing, or fracking, is the process used to excavate oil and gas trapped in shale rock.

The American energy revolution, otherwise known as The "Shale Gas Revolution," is described as being the big change in the ways in which we get our oil. In other words, it is a way of making the longevity of the oil we use as energy last just a little bit longer. The conventional oil we extract from the ground is rapidly running out, fracking, or hydraulic fracturing, is another way to get more oil out of the ground from less. Much of the oil we have left on Earth is trapped in shale rocks beneath the surface, not easily retrieved. These rocks are impermeable making it difficult to get to the oil enclosed inside. By the use of fracking, which opens up these rocks in order to let the natural gas and crude oil inside flow out, we increase the time in which we have oil left in the Earth, to use this valuable fossil fuel. According to Gold, in 2008 it was a small energy firm located in Canada that was first to administer a report entitled "The Shale Gas Revolution," which took to its supporters and is now used commonly. Gold believes in the revolution because he recognizes that the old ways of extracting the oil are crumbling, coal is no longer the major source of energy for making electricity, and a big change is occurring (Gold, 2014).

The water mixture used to break the shale rock contains sand as well as over 600 different chemicals. The amount of water needed just for one gas well to take place is over eight million gallons. Not only do these natural gas wells use up so much water, the methane gas and chemicals in the water contaminate nearby groundwater, causing the people who drink it to become very ill and suffer serious mental and physical injuries. Most of these companies who are in the business of drilling gas wells do not show what really goes on behind the scenes. The leftover fracturing fluid, which are retrieved after the fracking, is only half of what first went down the well. Not only is this a problem because the chemicals that are left sink further down into the ground but they are also not biodegradable, which could go on to contaminate more

Hydraulic fracturing, or “fracking” for short, is the process of extracting oil or gas from deep beneath the Earth’s surface by pushing water into shale rock to displace the oil or gas (Pritchard, 2013).

Hydraulic fracturing or fracking is the process of horizontal drilling past the water table into shale rock about 5,000 to 9,000 feet vertically and up to 10,000 feet horizontally. Then pressurized fracking fluid is pumped into the ground to bring the oil and natural to the surface. In the United States, there are more than 500,000 active natural gas wells.

According to an article in The New York Times, hydraulic fracturing is best described as the technique used to drill down into the earth using a high pressure water mixture to fracture the rocks and extract the natural gas and oil. Approximately one million wells have been fracked since the 1940’s, most of these are vertical wells that drill into porous sandstone or limestone. New technology has allowed for horizontal drilling to capture gas from shale rock. Water, sand and other chemicals are injected into the rock at a high pressure to create the fractures that release the gas. The chemicals added to the water dissolve minerals, kill bacteria that may plug up the well and

Hydraulic fracturing is either referred to as “fracking” or “hydrofracking.” It is a generally new technique for oil and gas extraction. Basically for shale gas and tight oil, including cracking of rock by a pressurized fluid. Even penetrating takes into account the infusion of very pressurized fracking liquids into shale rock layers profound inside the earth. After a well is drilled, it is cased with bond trying to guarantee groundwater security and the shale is using pressurized water broke with water, chemicals, sand and other fracking liquids. This makes new channels inside the stone from which natural gas is removed at higher than customary rates.

This report illustrates a geological review of a play within the South Brae oilfield and determines the potential of reservoirs within this area. It is hard to predict and provide ability for oil companies to license an oilfield before drilling therefore it is dependent upon several core sections available to investigate petrographically the northern North Sea. Cores and petrophysical data extracted from blocks 16/7a-A9, 16/7a-A17 and 16/7a-A21 related to licenses in block 16/07a found in the South Viking Graben area are provided and analysed in order to resolve whether exploration licenses should be purchased and the possible drilling of an exploration well.

There is a lot of controversy over the new practice of getting to fresh natural gas stored in the shale under our feet. The process has been named hydraulic fracturing, and as you can imagine, it involves water (hydro) and breaking stuff (fracking). The results that many people have been experiencing close to where this technique is used seem to be having
