Boat protest against Canaries oil prospecting

LANZAROTE, Spain: Protesters plunged half-naked into the icy sea and unfurled banners on Saturday (Dec 13) to try to stop oil prospecting near Spain's Canary Islands, a major tourist destination.

Ten boats from the archipelago took protesters eight nautical miles from where Spanish firm Repsol is exploring with a view to possibly drilling off the islands in the Atlantic ocean.
Protesters warn the oil and gas project is a threat to the environment and the tourist industry on which the Canary Islands rely. They say drilling would raise the risk of an oil spill like the Deepwater Horizon disaster that struck at a BP oil prospect in the Gulf of Mexico in 2010.

The government says finding oil could create thousands of jobs and reduce Spain's dependency on energy imports. The country currently imports 80 per cent of its energy. The beaches on the archipelago off northwest Africa are a popular draw for tourists from Britain, France and elsewhere.

Opponents of Repsol's operations are furious at the Spanish government for authorising Repsol to probe below the sea bed 50 kilometres from the islands of Lanzarote and Fuerteventura.

Environmentalists have branded it a threat to dolphins and other local fauna and flora. "I have been a boat owner for 10 years and what they are doing here pains me. I am sick of seeing the sea polluted and destroyed," said Samuel Rocio Garcia, 32, a protester who dived into the water.

On board one of the boats was the leader of the local government from the island of Lanzarote, Pedro San Gines Gutierrez. He said the protest was "a symbolic act of vigilance" to try to monitor the activities of the Rowan Renaissance, the ship Repsol is using to probe below the sea bed.

Spanish authorities last month temporarily impounded a boat of the environmental campaign group Greenpeace after it protested at the Repsol project in the same area. Spain said the crew had defied orders to leave a restricted zone.

On Nov 15, three Spanish navy boats rammed vessels in which Greenpeace activists were approaching the Rowan Renaissance, a video distributed by Greenpeace showed. An Italian protester fell in the water and was injured, Greenpeace said. It said its activists were protesting peacefully.

Greenpeace complaint halts Norway plans to drill northermost oil well

Environmental activists from Greenpeace have blocked plans by Norwegian state-owned oil company Statoil to drill the world’s northernmost oil well, the activists' organization told ITAR-TASS on Monday. Campaigners accuse Statoil of violating the law that bans drilling in ice and near an ice boundary. Russia to apply for Arctic shelf borders in 2015 — minister Sergei Donskoy said.

The halt was called as Transocean operators' Spitsbergen rig made its way towards the site in the Norwegian sector of the Barents Sea. Work is now on hold until a Greenpeace complaint is investigated, said the protest group's press officer, Maria Favorskaya.

Campaigners accuse Statoil of violating the law that bans drilling in ice and near an ice boundary. Norway's Polar Institute had shown the boundary was located just 25 kilometres from Statoil’s licensed area, said Favorskaya.

  • Oil production threatens Medvezhiy Island wildlife sanctuary, where the coast could be fouled by an oil spill reaching it from the exploration site within days, Greenpeace says.
This sanctuary of the Svalbard archipelago has been created to preserve a colony of birds and rare sea mammals, one of the largest refuges in the northern hemisphere.

Activists in the new campaign include some of those arrested by the Russian authorities in a protest against drilling by the Prirazlomnaya oil rig in Russian waters several months ago.

This time, aboard the vessel Esperanza, they have already visited Medvezhiy Island. They are now heading for the planned drilling site to ensure the oil company does not start work until the investigation is completed.

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.”

Oil and gas companies need the sand used in fracking operations to hold open cracks in shale rock. In Ohio, that rock is usually the Utica formation. In West Virginia and Pennsylvania, it’s the Marcellus shale.

Much of that sand is ripe for mining in upper Midwestern states such as Iowa, Illinois, Minnesota and especially Wisconsin.

Sand has long been used in various branches of industry in these states, but it has never been taken in such large amounts until the fracking method started to be used for extracting oil in gas in this area four years ago.

Local residents have various opinions about that. Some are claiming that the industry is ruining the once-idyllic land.

“Since 2012, Wisconsin has found nearly two dozen sand-mining operations in violation of air and water pollution rules,” an article in the Christian Science Monitor says.

No oil found in promising Mediterranean coastal well. -Despite favorable seismic reports and a $175m. investment, the Yam 3 well comes up dry.

Israeli oil drilling company Shemen Oil and Gas Resources Inc. said late Sunday that a promising offshore well in the Mediterranean Sea does not contain any oil. After drilling to 18,700 feet under the sea, at a total cost of about $175 million, it found after extensive production tests that the Yam 3 well was dry.

In late August, the company, whose chairman is former IDF chief of staff Gabi Ashkenazi, said that preliminary tests of the well — located about 10 miles off the coast of Ashdod — showed it could contain up to 120 million barrels’ worth of oil.  

The production test will only be finalized once all the equipment is removed from the well, Globes reported, leaving a “a small chance” that a technical failure was responsible for the data indicating a lack of oil or natural gas.
An independent seismic study had found that there was “a best estimate of 120 million barrels of oil in the license prospect, and a 36% chance of finding 1.8 trillion cubic feet of natural gas” at Yam 3, the report said.

Israel has made several large natural gas discoveries on the Mediterranean coast in recent years, which are typically invested in by a combination of private Israeli companies, the government, and foreign interests.

According to Globes, the Yam 3 well is majority-owned by Shemen Oil (78 percent), along with Caspian Drilling Company of Azerbaijan (10%), Zerah Oil and Gas Explorations of Israel (7%) and Zmiha Investment House (5%), also Israeli.

Study links fracking with methane-contaminated drinking water (+2video RT)

Household drinking water that comes from wells near known fracking sites contains levels of methane six times greater than what’s common elsewhere, a new study has found.
Researchers at Duke University sampled drinking water from 141 wells across northeastern Pennsylvania and southern New York and determined that the concentration of methane, the main component of natural gas, is much higher when those wells are within one kilometer of a hydraulic fracturing, or “fracking” sites.
Fracking is a method of drilling deep into the Earth in order to extract natural gas and has seen an emergence in recent years as an increasingly popular process used by energy companies. That spread in popularity is not without opposition from environmentalists and activists, however, who fear fracking has detrimental effects on the Earth.

According to the latest study, researchers have linked fracking sites with methane contamination several times over what is seen elsewhere. The scientists say that those high levels aren’t a direct result of the drilling, though, but caused in part by poor well construction that has allowed the water to become contaminated.
"It is looking like we are seeing a problem with well construction in some places and not others," wrote the study’s main author, Robert Jackson.
"Poor casing and cementing problems are the simplest explanation of what we found,” he said, but declined to single out well construction as the exclusive cause of the contamination.
"We need to understand why, in some cases, shale gas extraction contaminates groundwater and how to keep it from happening elsewhere," the researchers wrote.
Jackson and his crew determined that 82 percent of the 141 water wells tested had elevated levels of methane, with other additives appearing in unusually high numbers as well. In addition to finding methane concentrations at around six times the usual level, Jackson also found ethane concentrations 23 times higher in drinking water at homes near fracking sites. In ten of the sites located within one kilometer of a drilling, propane was detected in 10 separate water samples.
The methane, ethane and propane data, and new evidence from hydrocarbon and helium isotopes, all suggest that drilling has affected some homeowners’ water,” Jackson wrote.
Steve Everley, a spokesman for Energy in Depth, told the Wall Street Journal that Jackon’s study "is not a smoking gun to say that gas drilling is a problem."
"There is methane concentration near gas wells, but there is also methane concentrations in areas where there is no gas drilling," he said. Energy in Depth, wrote the Journal, is funded by the Independent Petroleum Association of America.
Jackson’s peer-reviewed study appeared in this week’s edition of the Proceedings of the National Academy of Sciences.

Companies line up to drill after survey shows Dakota oil, gas fields far bigger than believed

Energy companies are lining up for their shot to drill in the Dakotas and Montana after a new government report revealed that a massive geological formation stretching across the states contains twice the oil and three times the amount of natural gas than was originally believed.
While the new estimate is drawing smaller companies to the game, the larger players like Schlumberger, Halliburton and Continental Resources are pushing forward with ambitious multi-year plans to stake their claim in the industry.
Continental recently announced a five-year plan to triple its production by 2017. The company’s growth is based on success in North Dakota and Montana as well as in parts of Oklahoma.
The dash to drill follows news from the government on how much more oil and natural gas there is to tap.
“These world-class formations contain even more energy resource potential than previously understood, which is important information as we continue to reduce our nation’s dependence on foreign sources of oil,” newly confirmed Interior Secretary Sally Jewell said Tuesday in a statement.
The new U.S. Geological Survey estimates there are 7.4 billion barrels of oil, 6.7 trillion cubic feet of natural gas and 0.53 billion barrels of natural gas liquids in the Bakken and Three Forks Formations in the Williston Basin Province of Montana, North Dakota and South Dakota.
Since 2008, close to 450 million barrels of oil have been produced in the area and if the government estimates are correct, that leaves billions of barrels of oil and trillions more cubic feet of natural gas left for the taking.
That’s good news for North Dakota -- a state that’s already reaped big benefits from the oil boom and has one of the strongest state economies in the country coupled with an exceptionally low unemployment rate. Tax revenues from natural gas and oil hit $1 billion last year in North Dakota and the state is on track to double that number next year.
Republican Sen. John Hoeven believes numbers from the new USGS survey will draw even more developers to the area.
“This will mean a lot of jobs,” he told FoxNews.com. “Financially we are already very strong, we have no debt, but this will mean a lot more. Stores, restaurants, movie theaters – we’ll have to build and we’ll have to hire workers.”
The competition to court employees is already on at the McDonalds in Dickinson, N.D. where prospective hires are being lured in with $300 signing bonuses, Hoeven said.
Calls to McDonalds Corp. for comment were not immediately returned.
Some environmental experts like John Harju, associate director for research with the Energy and Environmental Research Center at the University of North Dakota, believe the possibilities are even greater than what the government forecasts.
“Like any of these USGS estimates, think of them as a milemarker that’s well behind you in the rearview mirror,” he told the Grand Forks Herald in North Dakota.
Still, not everyone is as gung-ho as Hoeven about drilling for natural gas, and the controversial process known as fracking used to access it.
The government hopes to calm some opposition to natural gas by releasing a set of draft rules to regulate hydraulic fracturing, or fracking. The process involves injecting a high-pressure mix of water, sand and chemicals deep into rock formations to release trapped oil and gas.
Supporters say the drilling method should continue and is credited for the country’s domestic energy boom. They say fracking gives the country a chance to cut its dependence on foreign oil.
Environmental groups have long objected to the practice and say it pollutes the groundwater and kills crops and livestock. They also argue that fracking releases heat-trapping methane gas into the air.
But in mid-April, the Environmental Protection Agency dramatically lowered its estimate of how much methane leaks during natural gas production. The agency said that tighter pollution controls put in place by the industry from 1990 to 2010 cut the country’s average of methane emissions by more than 850 million metric tons overall, or about 41.6 million metric tons annually. That’s a 20 percent decrease from previous EPA estimates – a decrease that took place as natural gas production in the country grew by nearly 40 percent in the past two decades.
  • It is not clear exactly when the government will release its fracking regulations, but it is expected in the next few weeks.
