Shale oil poses risks, controversy for Argentina(2)

About 24,000 oil barrels a day are produced in this Loma Campana field.

 Besides, the “flowback water”, which is separated from the oil or gas, is reused in further “hydraulic stimulation” operations, while the rest is dumped into “perfectly isolated sink wells,” he argued. “The aquifers do not run any risk at all,” he said.

But Dobrusin asked “What will they do with the water once the well is full? No one mentions that.”

According to Bizzotto, the seismic intensity of the hydraulic stimulation does not compromise the aquifers either, because the fissures are produced deep down in the earth. Furthermore, he said, the wells are layered with several coatings of cement and steel.

“We want to draw investment, generate work, but while safeguarding nature at the same time,” Neuquén’s secretary of the environment, Ricardo Esquivel said.

In his view, “there are many myths” surrounding fracking, such as the claim that so much water is needed that water levels in the rivers would go down.

Neuquén, he said, uses five percent of the water in its rivers for irrigation, human consumption and industry, while the rest flows to the sea. Even if 500 wells a year were drilled, only one percent more of the water would be used, he maintained.

But activist Carolina García with the Multisectorial contra el Fracking group stated: “That water is not left in the same condition as it was when it was removed from the rivers; the hydrologic cycle is changed. They are minimizing a problem that requires a more in-depth analysis.”

She pointed out that fracking is questioned in the European Union and that in August Germany adopted an eight-year moratorium on fracking for shale gas while it studies the risks posed by the technique.

YPF argues that these concerns do not apply to Vaca Muerta because it is a relatively uninhabited area.

“The theory that this is a desert and can be sacrificed because no one’s here is false,” said Silvia Leanza with the Ecosur Foundation.

“There are people, the water runs, and there is air flowing here,” she commented. “The emissions of gases and suspended dust particles can reach up to 200 km away.”

Nor does the “desert theory” ring true for Allen, a town of 25,000 people in the neighboring province of Río Negro, which is suffering the effects of the extraction of another form of unconventional gas, tight gas sands, which refers to low permeability sandstone reservoirs that produce primarily dry natural gas.

In that fruit-growing area, 20 km from the provincial capital, the fruit harvest is shrinking as the number of gas wells grows, drilled by the U.S.-based oil company Apache, whose local operations in Argentina were acquired by YPF in March.

Apache leases farms to drill on, the Permanent Comahue Assembly for Water (APCA) complained.

“Going around the farms it’s easy to see how the wells are occupying what was fruit-growing land until just a few years ago. Allen is known as the ‘pear capital’, but now it is losing that status,” lamented Gabriela Sepúlveda, of APCA Allen-Neuquén.

A well exploded in March, shaking the nearby houses. It wasn’t the first time, and it’s not the only problem the locals have had, Rubén Ibáñez, who takes care of a greenhouse next to the well, said. “Since the wells were drilled, people started feeling dizzy and having sore throats, stomach aches, breathing problems, and nausea.”

“They periodically drill wells, a process that lasts around a month, and then they do open-air flaring. I’m no expert, but I feel sick,” he said. “I wouldn’t drink this water even if I was dying of thirst. When I used it to water the plants in the greenhouse they would die.”

The provincial government says there are constant inspections of the gas and oil deposits.

“In 300 wells we did not find any environmental impact that had created a reason for sanctions,” environment secretary Esquivel said.

“We have a clear objective:  for Loma Campana, as the first place that unconventional fossil fuels are being developed in Argentina, to be the model to imitate, not only in terms of cost, production and technique, but in environmental questions as well,” Bizzotto said.

“All technology has uncertain consequences,” Leanza said. “Why deny it? Let’s put it up for debate.”
