Taking over shale gas shale oil can do?

Shale oil recently pocketed the world's attention, it is not only the traditional peak oil theory collapses, but also redraw the energy map of the United States, and even OPEC marvel shale oil power.

Shale oil recently pocketed the world's attention, it is not only the traditional "peak oil theory" collapse, but also redraw the energy map of the United States, and even OPEC marvel shale oil power. But shale gas shale oil will take over the baton do? Shale oil development is facing many problems also worth carefully consider.

Nearly two years,  shale gas  in the world as the hot energy star. However, shale gas revolution has allowed the U.S. natural gas prices fell to the lowest point decade, shale gas producers dubbed "Glad pants were gone." Nobody wanted to do Kuibenmaimai, belong to the shale oil shale resources, the development of marginal costs in the United States at 90 U.S. dollars / barrel, while the majority of shale oil producing areas, the average cost of only 60 U.S. dollars / barrel, earn money trading course attractive.

But shale oil is a "high-carbon" energy sources. While proponents of shale oil, this new fossil fuels can replace coal to reduce carbon emissions, but its essence is also a very high degree of carbon-intensive materials, ought to "carbon" energy sources. Shale oil extraction and use, would increase carbon emissions.

In fact, shale oil has sparked such a cheap energy will lead to overall carbon emissions increased concerns. PricewaterhouseCoopers recently released a report, along with the growing number of mining countries, relatively cheap shale oil is attracting a large number of the original plan into the field of renewable energy funding. A large number of the original will be devoted to research and development of renewable energy technology funds are flowing into shale oil mining project. Cheap shale oil reduces the development of renewable energy such as low-carbon technologies more attractive. If so, put the threat of global carbon emission reduction goals.

Shale oil development process pressure on the environment should not be overlooked. Shale oil production process consumes a lot of energy, and the mining process of carbon emissions than even the oil sands mining process of carbon emissions is also large. Shale oil extraction but also spend a lot of water. Shale oil  Hydraulic fracturing  needed cause serious environmental problems. Because during hydraulic fracturing, be 10% to 50% of the water is returned to the ground. The water not only contains various chemicals added artificially, still a lot of ground dissolved salts,Proppant  heavy metals, or radioactive substances.

Just Americans shale oil technology may bring "new golden age of oil" rejoiced when accompanying pipeline construction met block. Tens of thousands of people in the United States on February 17 held a rally in Washington national park, called Obama to honor his inaugural speech on the climate change commitments, King refused to build Keystone oil pipeline proposal. It is a gateway to western Canada from the Texas Gulf region, supporting with shale oil pipeline. Some environmentalists event organizers estimated that 35,000 people braved the cold to attend the rally, and called it the largest in U.S. history, climate rally.

And exploitation of shale oil is not sustainable. Practical experience has shown that once mined shale wells, production would drop dramatically. More importantly, fracturing method to reduce oil production wells mined quickly, usually in the first year rate of decline of 65% in the second year rate of decline of 35%. This also explains why a few years, a fractured wells in production can only be maintained at 100 barrels of daily production, or even less.
