REPOST: California's clash: Shale oil or green energy

California is divided by opinions concerning the economy and the environment. Forbes.com gives the full details.

California’s economic predicament and environmental progression have met head on. But the state’s leaders are saying that the two dynamics can be reconciled, all to potentially capture the nation’s richest “tight oil” deposits.

At issue now is the Monterey Shale, a formation holding more shale oil than anywhere else in the country. It could be a potential gold mine if developers could find a way to extract it and if regulators could appease the environmental community there. Governor Jerry Brown, who has the staunch support of green groups, says that California needs that oil wealth and that the state’s regulators could ensure that the drilling techniques meet strict standards.

“We want to get the greenhouse gas emissions down, but we also want to keep our economy going,” says Governor Brown, during a press conference on March 13. “That’s the balance that is required.” Indeed, the Monterey Shale, which stretches from Central California down through Southern California, holds 15.4 billion barrels of recoverable crude oil, says the U.S. Energy Information Administration. By comparison, North Dakota’s Bakken Field has 3.6 billion barrels — a place that now has 3 percent unemployment. Nationally, 25 billion barrels in proved unconventional shale oil exists.

California has a jobless rate of 9.5 percent. Its budget deficit has been as high as $26 billion, although recently approved tax hikes will cut that way down — a move that could cause some of the state’s business to relocate. According to a study done by the University of Southern California, tapping the Monterey Shale would bring in 2.8 million new jobs while raising an additional $25 billion in new revenues by the end of the decade. Interestingly, California now produces nearly 10 percent of the nation’s oil, which is on par with that of Alaska. Among the leading developers there areChevron and Occidental Petroleum, as well as Plains Exploration, Linn and Breitburn. Altogether, at least 32 drilling sites exist both on land and offshore, all places from where those companies are exploring for oil and doing so without incident.

The primary obstacle to increasing that percentage is, ironically, technological — not regulatory, says Rock Zierman, chief executive of the CaliforniaIndependent Petroleum Association, in Sacramento.

He says that the Monterey geological formation is uncommon, and at present, hydraulic fracturing cannot work there. Fracking, of course, is the controversial method by which producers extract tight oil and gas — a process that uses a concoction of water, sand and chemicals to break those deposits free from the rocks where they rest a mile beneath the ground.

“Our geology is totally different here,” says Zierman, in a phone conversation. “We have not found out how to produce the Monterey Shale. Now, there are dozens of bills that have been introduced to try and shut us down — before we would get started. They could become a problem. But, today, they are not.”

The potential for a run-in is real, however. California’s environmental goals are cultivated by a “global warming law” requiring greenhouse gas reductions of 25 percent by 2020. Voters there rejected an effort in 2010 to rollback that statute until unemployment fell, noting that “new energy” jobs there total around 500,000. Billions, meanwhile, are pouring in from venture capitalists.

Governor Brown is taking a pragmatic approach: Developing California’s oil fields would not only alleviate the economic suffrage there, he told reporters, but it could also provide fuel to the state’s 30 million licensed vehicles. Until people stop driving cars that burn gasoline, those vehicles will need to be fed, he says. California can either continue to import that oil from other nations, or it could aid in its recovery by producing much of it, he adds.

But do not exploratory methods require tons of water — a resource that California cannot afford to spare? According to Zierman with the petroleum group, the state’s golf courses combined consume more water in a day than the oil and gas drillers do in a year.

Are oil and gas developers at eternal odds with the environmentalists? Public policy is often reactive, necessitating immediate action after the fact. If things got desperate, more oil drilling would occur to meet demand and to curb prices both in California and elsewhere.

Throughout the country, new areas are opening up to shale development, with restrictions. Industry is complaining that such oversight is burdensome. But environmentalists are dismayed that pristine regions are even accessible.

Therein is the dilemma, which is how to promote economic development while limiting emissions and degradation.

“Wherever there is an environmental consequence, regulators could require developers to offset that with an environmental gain,” says Bob Bellemare, chief operating officer for Mykrobel, an energy consulting firm in New Mexico. “Markets work better when there are regulations on which industry can depend.”

California has reached a crisis point. As such, Governor Brown wants to pursue the idea of increasing oil production there as a way to provide jobs, boost tax revenues and fuel the auto sector. Achieving those goals, however, cannot negate the ongoing environmental achievements — a proposition to which there are many unresolved questions.

REPOST: US oil production 'to jump by a quarter by 2014'



This BBC News article talks about the increase of US oil production in 2014 due to the discovery of vast reserves of shale oil.

US oil production will jump by a quarter by 2014 to its highest level in 26 years, figures suggest.

This is mainly because of the discovery of vast reserves of shale oil.

The Energy Information Administration (EIA) in the US also forecast average global oil prices would fall from $112 a barrel in 2012 to $99 in 2014.

It said US oil imports would fall by a quarter between 2012 and 2014, because of rising domestic production and the discovery of shale gas.

US oil imports have been falling since 2005, when they stood at 12.5 million barrels a day. By 2014, they will have halved to six million barrels, the EIA said.

Domestic production, which stood at 6.4 million barrels last year, will rise to 7.9 million barrels next year, the highest level since 1988.

"US oil production is rising extraordinarily quickly, entirely because of the application of fracking, [which is] unleashing very significant new resources into the market," Seth Kleinman, global head of energy strategy at Citigroup, told the BBC.

Fracking is the process of blasting water at high pressure into shale rock to release oil or gas held within it. It has become widespread in the US and domestic gas prices have plummeted as a result.

Many have hailed shale gas as the saviour of the US energy market. In fact, the International Energy Agency (IEA) has said it expects the US to overtake Russia as the world's biggest gas producer by 2015 and to become "all but self-sufficient" in its energy needs by about 2035.

But critics of shale gas point to environmental concerns such as high water use and possible water contamination, the release of methane and, to a lesser extent, earth tremors caused by drilling.

The process has been banned in France, while the UK recently lifted a moratorium on drilling for shale gas.

Transformational shift

Shale gas also helps to explain the sharp drop in US oil imports forecast by the EIA in the next two years.

The move away from oil "is being driven by tighter fuel economy mandates and the transformational shift from oil to natural gas, which is extraordinarily cheap compared with oil", says Mr Kleinman.

But the US will continue to increase oil production for domestic use and to generate revenues from exports.

The US will overtake Saudi Arabia as the world's biggest oil producer "by around 2020", an International Energy Agency (IEA) report predicted at the end of last year.

In fact, global oil production will continue rise, thanks to the discovery of shale oil.

"Total oil production is about to rise," Fatih Birol, chief economist at the IEA, told the BBC.

"We estimate total oil production to reach about 100 million barrels a day, about 20 million higher than today.

"This growth comes from unconventional [shale] oil."

The discovery of shale oil means global oil production will not peak in the next 20 years, Mr Birol added.

The increase in oil production comes at a time when coal production is also rising sharply, largely to provide cheap energy to meet exploding demand in developing economies, particularly in Asia.

The increase in production of both coal and oil has raised concerns about meeting carbon dioxide emissions targets, designed to slow the rate of increase in global temperatures.
