Using sand for fracking: pros and cons

Disputes about pros and cons of fracking are still going on in the US, especially in Midwestern states. Although there are no fracking facilities in some Midwestern states, these states are now experiencing a big increase of the sand mining industry. The reason is that the process of fracking needs large amounts of sand.
The Christian Science Monitor describes the process as follows: “To extract the sand, mining companies scrape away the soil, break up the sandstone with explosives, and then crush it. The raw sand is washed, sorted by size, and shipped by truck, rail, and barge to fracking operations in the US and Canada. There the sand is mixed with water and chemicals and pumped underground, where the particles lodge in cracks and prop them open while gas or oil flows out.”

Günther Oettinger: Wir brauchen in Europa die Option des Fracking“.

EU-Energiekommissar Günther Oettinger empfiehlt Europa die Gewinnung von Schiefergas nach US-Vorbild. Nur so könne sich der Kontinent aus der Abhängigkeit von Russland befreien. 

WienUm die Wettbewerbsfähigkeit Europas zu sichern, befürwortet der EU-Energiekommissar Günther Oettinger die Gewinnung von Schiefer-Gas nach amerikanischem Vorbild, in der Branche Fracking genannt. "Wir brauchen in Europa die Option des Fracking, zumindest als Drohung gegen Putin", sagte Oettinger auf der Handelsblatt-Tagung Energiewirtschaft am Montag in Wien. Russland ist bislang wichtigster Gaslieferant in der Europäischen Union. Noch liefert das von Wladimir Putin regierte Land vier Fünftel des Gases.

Ukraine’s Shale Gas Plans Pose Danger for Russia – WWF. -Russia cannot compel Ukraine to present an international assessment of the project’s risks because Russia has not ratified the United Nations’ Espoo Convention.

MOSCOW, October 31 (RIA Novosti) –
Planned drilling for shale gas in Ukraine is likely to pollute downstream waters in neighboring Russia, environmental conservation group the World Wide Fund for Nature said Thursday.

Ukraine last year announced a joint project with Europe’s biggest oil company, Shell, to drill for shale gas in the eastern Kharkiv Region, which borders Russia. Extraction is due to begin in 2018 or 2019.

The project is expected to decrease Ukraine’s current dependence on natural gas from Russia following a series of so-called gas wars that saw Moscow using the lucrative resource for political leverage.

Fracking water injection could trigger major earthquake, say scientists

Pumping water underground at geothermal power plants can lead to dangerous earthquakes even in regions not prone to tremors, according to scientists. They say that quake risk should be factored into decisions about where to site geothermal plants and other drilling rigs where water is pumped underground – for example in shale gas fracking.

Prof Emily Brodsky, who led a study of earthquakes at a geothermal power plant in California, said: "For scientists to make themselves useful in this field we need to be able to tell operators how many gallons of water they can pump into the ground in a particular location and how many earthquakes that will produce."

Romania warns of independent energy policy after Nabucco failure

By Daniel Stroe – Bucharest
- The Romanian President Traian Basescu today pointed out he had informed the European Council that Romania will redefine its energy policy based on its own resources and without awaiting anybody’s approval, two days after the failure of the EU-backed Nabucco project which Romania was part of.

Basescu made these statements in a press conference at the end of the European Council in Brussels. “Without going into details, the option now without any doubt is Romania being forced to accelerate the evaluation process and move to exploiting the shale gas and the gas and oil already confirmed in the Black Sea” he said.
