Shale

name for hydraulic fracturing, is a method of extracting natural gas from the earth. In this process, a well is drilled deep into the earth to reach shale. Once it hit this level, the well takes a ninety-degree turn and runs through the layer. Water with other dissolved chemicals is pressurized and sent down the well to create cracks in the shale. This solution helps absorb the gas and is subsequently pumped back up the well to the surface (NYTimes). The controversies surrounding fracking…

sandstones, limestones and shales far below ground contain natural gas. When the rocks are drilled this gas is released and can be captured at the surface to be used (source A). To increase the flow of released gas, the rocks can be broken apart, or fractured. Fracking has led to many controversial opinions because critics say the process carries many risks but some say there are many benefits to fracking. Some of the benefits include that there is enough fossil fuels in bedrock shale formations…

activists have hindered the use of fracking. Hydraulic fracturing should be more widely used. Originally, fracking was the process of placing gunpowder down a vertical shaft and the generated explosion would create cracks in the shale. The natural gas inside the shale would be released and collected above. Fracking began in the late 1800s and the use of gunpowder remained for decades. Gunpowder was abandoned…

Recognized as being one of the richest sedimentary basins in petroleum and gas for its comparatively small size, the Los Angeles Basin is a Neogene age sedimentary basin whose complex formation history makes it a unique marvel of the western continental margin (Ward, 1994). In order to understand the importance that the discovery of oil has had in the Los Angeles Basin, we look to the events that have taken place in the basin itself that created the conditions necessary for the formation of oil.…

earth’s crust and injecting water, sand and chemicals under immense pressure in order to obtain natural gas. With this process there are benefits and also disadvantages. There are many risks to groundwater from surface spills that are associated with shale energy development, they can be managed or mitigated by following certain precautions and steps. Groundwater is present throughout the atmosphere. There is surface water, atmospheric water and groundwater. It is something both humans and…

decade or so a new trend in the way we extract our natural gases has gained popularity. Hydraulic fracturing better known now as “fracking” has become the most worthwhile option for business's. “According to the Energy Information Administration, shale gas will account for nearly half of the natural gas produced in the U.S. by 2035.” (McGraw) Fracking has to potential to be a temporary feasible option to solve our energy…

US Oil Embargo Lifted- Is It A Big Deal The lifting of the oil embargo is the Silver lining, which will encourage the Shale oil drillers to continue pumping at rock bottom prices. The possibility of better times in the future will encourage them to cut costs and survive the current crisis. There are a number of questions associated with the lifting of the ban, who will benefit from this? Will gasoline prices rise at the pump? Who will buy from the US when there is so much of supply glut in…

technologies for shale gas production and keep refining it In October 2012. Dependence on gas imports by US has decreased by 45% over the years. At the moment, the European gas market might witness a momentous transition if shale gas is developed successfully in the next 2 to 3 years. Europe might emerge as a significant shale gas producer and the production of shale gas in Europe would completely alter its energy structure. Gazprom might lose their market in EU as potential of shale gas in…

hurt the environment but also the people and wildlife living in it. Fracking is short for Hydraulic Fracking. Fracking is drilling deep into the earth’s crust and injecting chemicals to collect oils and gas. Fracking is unnaturally creating cracks in shale rock and cause earthquakes. It is dangerous for people living in and around fracking sites. The ground water becomes contaminated and the air is polluted with disease and cancer causing chemicals. The negatives outweigh the few positives from…

approximately 100 m apart. The authors examined 8 lithofacies types in their study area: massive sandstone, sandstone with floating mudstone clasts, pebbly sandstone, contorted sandstone, contorted shale, mudstone/shale with floating clasts, laminated and rippled sandstone and siltstone, and laminated shale. These lithofacies were interpreted based on depositional processes. At DeGray Spillway, 794 units were measured and 189 units were measured at Kiamichi Mountain. A composite…
