Ai idee care sunt costurile de exploatare ale gazului de sist? Sunt mult mai mari decat pentru cel "clasic". Practic, pana nu se incepe productia, nici macar nu se stie daca isi vor scoate costurile. Ar fi de rasul curcilor, dar nu m-ar mira deloc sa ajungem sa le subventionam printr-o scamatorie ca "certificatele verzi". "Medlock's team extensively researched U.S. shale gas play breakeven prices, a major discussion topic and source of disagreement among analysts and industry participants in recent years. Everyone wants to know what Henry Hub benchmark gas price is required for an unconventional well to recoup costs and turn profitable. The less than satisfying but most accurate answer is "it depends." "Some wells are profitable at $2.65 per thousand cubic feet, others need $8.10 … the median is $4.85," Medlock said. The presence of natural gas liquids—which fetch higher prices than dry natural gas—is one major factor, but infrastructure access, lease costs, local fiscal conditions and other variables contribute to well economics. " (...) " For example, a 10,500 vertical foot well with a 4,000 foot lateral in the Haynesville Shale costs about $8 million, Medlock said, but the same well in Poland would cost $14 million to $16 million. This is because shale gas development in Eastern Europe is an immature industry and a company would need to import equipment, fracking crews, etc." http://www.telegraph.co.uk/finance/n...is-a-myth.html Acum fa tu un calcul cat cati m3 de gaze trebuie sa extraga o sonda din asta, ca sa acopere costul (vreo 10mil $ numai, sa zicem, + intretinere pe perioada exploatarii + redeventele de exploatare + macar 10% profit). Eu cred ca e mai ieftin, proftabil sa cumparam gaz de la rusi, pur si simplu.

Ca sa pun si eu gaz peste foc, sar si eu cu ceva informatii...
PUBLIC RELEASE DATE: 16-Dec-2013 [ Print | E-mail ] Share Share [ Close Window ] Contact: Jenni Glenn Gingery jgingery@endocrine.org 301-941-0240 The Endocrine Society Fracking chemicals disrupt hormone function Endocrine-disrupting activity linked to birth defects, infertility found near drilling sites Chevy Chase, MD—A controversial oil and natural gas drilling technique called hydraulic fracturing, or fracking, uses many chemicals that can disrupt the body's hormones, according to new research accepted for publication in The Endocrine Society's journal Endocrinology. Endocrine-disrupting chemicals, or EDCs, are substances that can interfere with the normal functioning of the endocrine system. EDCs can be found in manufactured products as well as certain foods, air, water and soil. Research has linked EDC exposure to infertility, cancer and birth defects. "More than 700 chemicals are used in the fracking process, and many of them disturb hormone function," said one of the study's authors, Susan C. Nagel, PhD, of the University of Missouri School of Medicine. "With fracking on the rise, populations may face greater health risks from increased endocrine-disrupting chemical exposure." The study examined 12 suspected or known endocrine-disrupting chemicals used in natural gas operations and measured their ability to mimic or block the effect of the body's male and female reproductive hormones. To gauge endocrine-disrupting activity from natural gas operations, researchers took surface and ground water samples from sites with drilling spills or accidents in a drilling-dense area of Garfield County, CO – an area with more than 10,000 active natural gas wells – and from drilling-sparse control sites without spills in Garfield County as well as Boone County, MO. The water samples from drilling sites had higher levels of EDC activity that could interfere with the body's response to androgens, a class of hormones that includes testosterone, as well as the reproductive hormone estrogen. Drilling site water samples had moderate to high levels of EDC activity, and samples from the Colorado River – the drainage basin for the natural gas drilling sites – had moderate levels. In comparison, little activity was measured in the water samples from the sites with little drilling. "Fracking is exempt from federal regulations to protect water quality, but spills associated with natural gas drilling can contaminate surface, ground and drinking water," Nagel said. "We found more endocrine-disrupting activity in the water close to drilling locations that had experienced spills than at control sites. This could raise the risk of reproductive, metabolic, neurological and other diseases, especially in children who are exposed to EDCs." ### Other authors of the study include: C.D. Kassotis, J.W. Davis and A.M. Hormann of the University of Missouri, and D.E. Tillitt of the U.S. Geological Survey. The study, "Estrogen and Androgen Receptor Activities of Hydraulic Fracturing Chemicals and Surface and Ground Water in a Drilling-Dense Region," was published online, ahead of print. Founded in 1916, The Endocrine Society is the world's oldest, largest and most active organization devoted to research on hormones and the clinical practice of endocrinology. Today, The Endocrine Society's membership consists of over 17,000 scientists, physicians, educators, nurses and students in more than 100 countries. Society members represent all basic, applied and clinical interests in endocrinology. The Endocrine Society is based in Chevy Chase, Maryland.

Ce se intampla cu solidaritatea romanilor din toata tara cu cei de la Pungesti, aflati in greva foamei? Oare e normal sa fie lasati singuri, atata timp cat acesti oameni ne reprezinta si interesele noastre? Cu totii avem nevoie de apa freatica necontaminata si de un pamant pe care casele sa fie in siguranta, nu zguduite in fiecare noapte de mai multe ori de cutremure.

Absolut orice partid sau formatiune politica ar conduce Romania lucrurile ar sta la fel. Ocazia Romaniei a fost in '89-'90. Si atunci romanii (nu altii) au ales sa ii dea cu piciorul. Ce se intampla acum este doar o consecinta fireasca.

Chiar daca exceptiile sunt putine, tocmai la aceste exceptii ma gandisem. Sa numim unele exceptii, care merita increderea noastra.
Eu, de exemplu, il stimez pe Mihai Neamtu de la Noua Republica. Da voi? |

Daca nu se cunosc costurile, sa se lase pagubasi. Cum sa pornesti la drum cu o exploatare, cand nu stii cat te costa?!? Mai ales ca localnicii se opun, si pe langa ei, o lume intreaga e constienta de pericolul pe care il implica aceasta exploatare a gazelor de sist.
