Health, safety and environmental risks of shale gas extraction is given the all clear by the UK government in the Autumn 2012 Statement
December 2012 saw the final ruling and approval of the fracking industry within George Osborne's Autumn Statement 2012. The released news now means that the temporary ban on fracking has been lifted. Fracking work carried out by UK companies with a license can now continue as planned. It is the company's responsibility to monitor the effects of the fracking process that is being carried out as ...

Cracking down on Fracking: The US Regulatory Trend and what that means for Oil Companies
In June 2011 Enhesa is focusing on an emerging Oil & Gas issue, which has recently become a major concern for Oil Companies in the United States. Hydraulic fracturing or “fracking” has long been used for natural gas and oil production in the United States. However, due to growing concern on its environmental impacts, the US Federal Government and various states are assessing the ...

Shale gas - Information on hydraulic fracturing (`fracking`)
Shale gas is natural gas – mainly methane – trapped within the micropores of shale formations or adsorbed onto the shale (sedimentary rock). In Europe, known deposits exist in the UK, France, the Netherlands, Germany, Poland, the Baltic States and Scandinavia. In Switzerland, deposits are suspected to lie in the Permo-Carboniferous trough of Northeastern Switzerland, below Lake ...

Pumps that thrive under pressure
The Evolution of Hydraulic Transmission Technology in the Pressure Pumping Market. Fracking technology is driving transformation of North American energy production capabilities. Since 2005, most of the increase in domestic natural gas production resulted from ongoing development of horizontal drilling and hydraulic fracturing technology. Producers developed more efficient ways to extract gas ...

FRACKING: Freeing Energy Resources versus Polluting the Earth and Public Health with Radiation and Toxic Chemicals?
Fracking demands the use of millions of gallons of water, precious drinking water, and sand infused with up to 1,000 different toxic chemicals to fracture the shale rock and release the trapped gas or oil. The wastewater, brine, and sludge are then returned to the surface and in need of disposal. Unfortunately there is not yet a clear and safe method of disposal or storage. Among these chemicals ...

The Future For Fracking
Summary -Fracking is an essential technology to meet growing global demand for oil and gas. -Fracking has become the "F" word, because it is very water-intensive, and has potential negative impacts on the environment. -The future of fracking will be constrained if adequate water is not available and if solutions for decontaminating wastewaters are not found. -Oil sands production faces the same ...

The Stats on Fracking: The Real Numbers of Hydraulic Fracturing
Hydraulic fracturing, sometimes referred to as “fracking,” is among the largest and most influential trends in the global energy sector today. By injecting highly pressurized fluid into underground formations containing oil and natural gas, hydraulic fracturing makes it possible to exploit fossil fuel reserves that were previously too expensive or too difficult to reach with more ...

The Middle East should think twice about fracking
Securing energy resources is critical for fuelling development, but deciding which types of energy to invest in will affect a country’s future in many ways — and not all are good when it comes to shale gas. Four countries in the Middle East and North Africa (MENA) — Egypt, Jordan, Saudi Arabia and Tunisia — are planning to extract shale gas, and one, Algeria, is said to ...

Effect of shear rate on the activity of enzymes used in hydraulic fracture cleanup of tight unconventional reservoirs
Injection of polymeric solutions in order to propagate a fracture and carry proppants to keep the fracture open is a common practice in hydraulic fracturing of ultra–tight formations. Polymeric fluids open and extend the already existing network of fractures. Considering the low permeability of the formation, small width of the micro–fractures, and the importance of fracture cleanup during the ...

Optimizing Water Management in Hydraulic Fracturing for Shale Oil and Gas Production
Centralized treatment of wastewater is emerging as a viable solution for long-term efficiency in managing water sourcing and wastewater treatment in hydraulic fracturing. The number of hydraulic fracturing (fracking) shale oil and gas wells in the United States continues to increase. Within the Bakken Shale formation alone, in North Dakota and Montana, upwards of 15,000 hydraulic fracturing ...

New York governor pauses `fracking`
New York Gov. David Paterson has signed an executive order halting the controversial natural gas drilling process called hydraulic fracturing until July 1. The process --- also known as "fracking" -- has come under scrutiny because of its alleged harmful effects on underground drinking water and the environment -- although industry leaders have insisted it's safe. The governor's order -- which ...

Health alert over fracking’s chemical cocktails
Fracking is once again in trouble. Scientists have found that what gets pumped into hydrocarbon-rich rock as part of the hydraulic fracture technique to release gas and oil trapped in underground reservoirs may not be entirely healthy. Environmental engineer William Stringfellow and colleagues at Lawrence Berkeley National Laboratory and the University of the Pacific told the American Chemical ...

EPA Considering Rule to Require Reporting Of Chemicals Used in Hydraulic Fracturing
The Environmental Protection Agency is considering a rulemaking that might require chemical manufacturers and processors, as well as oil and gas exploration companies, to report on chemicals used in hydraulic fracturing. In an advance notice of proposed rulemaking, the EPA said it is seeking information from industries, state agencies and others on the range of data the agency should obtain ...

Solution blooming for fracking spills?
Blooming salts may clean up after brine spills North Dakota's oil boom can have a salty side-effect. Wastewater from oil drilling and hydraulic fracturing – or fracking – is often laden with salts and can spill, contaminating soils. In 2014, for example, 42 such brine spills per week, on average, were recorded in North Dakota. Brine spills introduce so much salt into the soil that ...

Halliburton hunts new bacteria killer to protect Shale-gas boom
Halliburton Co. and Schlumberger Ltd., trying to forestall a regulatory crackdown that would cut natural-gas drilling, are developing ways to eliminate the need for chemicals that may taint water supplies near wells. At risk is hydraulic fracturing, or fracking, a process that unlocked gas deposits in shale formations and drove gains in U.S. production of the fuel. Proposed regulations might ...

Why many experts missed this: Cheap oil can hurt US economy
WASHINGTON (AP) - If there was one thing most economists agreed on at the start of the year, it was this: Plunging oil prices would boost the U.S. economy. It hasn't worked out that way. The economy is thought to have shrunk in the January-March quarter and may barely grow for the first half of 2015 - thanks in part to sharp cuts in energy drilling. And despite their savings at the gas pump, ...
