Until the ,shale gas, bubble and the recession, natural ,gas, cost 3-4 times as much as it does today. On a per unit heat basis, it is trading at an historically high spread compared to crude oil. I continue to maintain that is an unnatural situation that has been enabled by exempting the industry from many long existing federal laws that were designed to protect the commons from potentially ...

16/2/2017, · Thus, hydraulic fracturing is used to, facilitate entry into the well, or, to improve the gas/oil flow by reopening, the pores to bring it to the surface at, higher rates,. Therefore, the rock is fractured by high pressure or rather fluids are pumped into the well at pressures sufficient to create cracks in the formation using different types of technologies and fluids.

The claim that water shortages would arise as a result of ,shale gas, development has also been greatly exaggerated. The demand for water from the operators will be similar to that from other industrial users. Moreover, technological advances will allow the use of saline water and ,recycling, of ,flow-back, water, reducing the need for fresh water.

26/10/2011, · The higher emissions from ,shale gas, occur at the time wells are “hydraulically fractured”as methane escapes from “,flow-back, return ,fluids,”and during drill out following the ,fracturing,. Methane is a powerful greenhouse ,gas,, with a global warming potential that is far greater than that of carbon dioxide, particularly over the time horizon of the first few decades following emission.

Since the dawn of the fracking revolution, ,shale gas, from horizontal wells has been ,near, the bottom of the league tables with respect to EROEI which means it “…has decreased from more than 1000:1 in 1919 to 5:1 in the 2010s, and for production from about 25:1 in the 1970s to approximately 10:1 in 2007” for US oil and ,gas, according to Hall et al. (2014).

The need for disposal of ,flow-back, water occurs only during the drilling of a new well, however ,flow-back, water disposal is often the second-largest expense of drilling a new well. Water that comes to the surface during the normal oil or ,gas, production process is naturally occurring briny water that is generated from deep within the earth along with the oil and ,gas,.
