Toreador: unconventional shale oil IdF

These are very active surfactants (or soaps) which penetrate the skin and internal cells by making holes in them and therefore extremely dangerous !!
It would be good to have typical chemical compositions to further research their actual effects.

Shale oil: drilling would be imminent

Another unconventional hydrocarbon even more unknown than shale gas is likely to be talked about in the coming days: shale oil is indeed the subject according to Greenpeace "of exploration projects in the North of the France".

Recall that the government, through its Minister of Ecology, Nathalie Kosciusko-Morizet, said to suspend all drilling and hydraulic fracturing operations until May 31, concerning shale gas in the South of France .

However, Greenpeace reveals that for shale oil exploration projects in the Paris basin, only fracking operations are suspended until May 31. Thus, the first vertical drilling should start in mid-April, while preliminary work (earthworks, pilot hole) is already underway near Château-Thierry.

"There is a certain confusion between the question of shale gas and oil, and the government maintains this artistic vagueness, explains Anne Valette, in charge of the Energy-Climate campaign for Greenpeace France. He actually left the door open at the start of operations in Aisne and Seine-et-Marne from April 15. "

Same causes, same effects for soil and climate

According to official documents from the companies Toreador and Vermillion, which lead the exploration for this shale oil, it is nestled very deep in the heart of the rock. "The planned vertical drilling would be of no use if it were not followed by the use of this famous and so dangerous hydraulic fracturing technology" explains the non-governmental organization.

This consists of fracturing the rock at depth to extract hydrocarbons, gas or petroleum, by injecting huge quantities of water and chemicals. The risks of soil and water pollution are great. In addition, the impact of shale oil on climate change is catastrophic. The production of fuel from shale oil - extremely energy-intensive - emits up to 5 times more CO2 than the production of so-called conventional oil.

France is not the only one affected by this phenomenon, and for several years, Greenpeace has campaigned against so-called "unconventional" oils everywhere on the planet. Last January, she launched the “Petrol addict” campaign to denounce - with humor - our society's addiction to petroleum, the symbol of which is the headlong rush towards unconventional oils like shale oil.

Fracking, KEZAKO?

To better understand the process of hydraulic fracturing, we also invite you to watch the animation published by the New-York Times >>>>> HERE

Shale oil, along with the oil sands, are the most expensive, the dirtiest, the most polluting oils.

A standard well requires approximately 10 to 15 million liters (10 to 000 m15), although the quantities may vary depending on the geology and the nature of the well.

The potential composition of the fracturing liquid (used by Questerre in Quebec in particular) is as follows: water, flexible silica sand, and a series of chemicals, polyacrimalide, isopropanol, trimethyloctadecylammonium, sodium xylene sulfonate, sodium hypochlorite, sodium gum guar, low toxicity base oil, quaternary amine, trisodium nitrilotriacetate monohydrate, isopropanol, methanol, tibutyl phosphate, hydrochloric acid.

Almost 50% of fluid residues (water + sand + chemicals) remain underground and the remaining 50% rise to the surface. The recycling of this polluted water is long, very expensive and uses chemicals again to treat the water.

Beyond chemicals, wastewater rising to the surface may contain heavy metals, such as aluminum, antimony, arsenic, cobalt, chromium, iron, lead, nickel, molybdenum, tin, vanadium. , zinc, etc.

In the event of a leak, in particular via a crack in the cementing of boreholes, these chemicals can seep into the underground water tables.

When we look at the map https://www.econologie.com/forums/gaz-de-sch ... 10542.html this is no longer conditional and prospecting drilling has already started !! There are at least 2 near Maloche. But that does not mean that there has already been hydrofracturing in France.

And to say that there have been nearly 500 wells in the USA for about 000 years ... it took gas country to make the world worry ...

In this subject of oil difficult to extract, the oil extracted with solar energy to heat the water necessary to make the oil come out:
Greenhouse solar plant for cheaper extraction of oil
http://www.physorg.com/news/2011-03-gre ... r-oil.html

producing steam is the largest cost in thermal extraction of oil. He said that with the solar assistance they can get 10-20 percent more oil from the same well because the cheaper steam means you can run the extraction longer ...
Around 40 percent of Californian oil is extracted using steam heated by natural gas, and oil extraction is the greatest industrial use of natural gas in the state.

No info on pollution !!

Is hydraulic fracking re-authorized in September ?

A rapporteur from the State Council deemed the complaint of an oil tanker worthy of examination by the Constitutional Council. This winding legal path could lead to the return of this controversial technique.

The ban on hydraulic fracturing hangs by a thread. Or rather a simple opinion of the Constitutional Council. Since the Jacob law of July 13, 2011, the use of this shale gas extraction technique, the only one deemed credible to date but dangerous for the environment, has been ruled out. Massive injection of water, use of chemicals, risks of pollution of groundwater and methane leaks, the many unknowns and the American experience urged parliamentarians to be cautious. Much to the dismay of the oil tankers. For two years, their drilling licenses have been frozen or even repealed.

But the counter-attack is organized. In February, when Total had just filed an appeal against the repeal of its Montélimar (Drôme) license, the oil tanker Schuepbach Energy decided to attack the law directly. By filing a QPC, a priority question of constitutionality, the group initiated a long and complicated procedure. This Wednesday, at the Council of State, he won a second victory.

Why is the law on hydraulic fracturing threatened?

Because, according to the Schuepbach group, it would not respect the Constitution. This American oil company obtained, in 2010, two drilling permits in France, one in Ardèche, the other in Aveyron. Today he challenges their repeal. His lawyers saw the Jacob law as an excessive application of the precautionary principle. In February, they therefore filed a priority question of constitutionality before the administrative court of Cergy-Pontoise (Val-d'Oise). For the Ministry of Ecology, which defends the law of 2011, the procedure should have ended there. But the judges of Cergy-Pontoise did not follow his opinion and considered, in March 2013, that the question deserved to be transferred to the highest French administrative body: the Council of State.

We are going to add the trinitrotulene recipe.
