ALASKA HAS A NEW OIL BOOM THANKS TO LARGE-SCALE FRACKING

BY SCOTT L. MONTGOMERY ON 4/15/17 AT 6:40 AM

OPINION FRACKING OIL AND GAS ALASKA
This article originally appeared on The Conversation.

UPDATED | Arctic lands and waters hold irresistible allure for global oil companies. Despite opposition from environmental groups and President Obama’s 2016 ban on drilling in federal Arctic waters, exploration in Alaska has revealed massive new volumes of oil.

This comes at a time of low oil prices, when many observers felt the Arctic would remain off limits. Alaska has proved precisely the opposite. Although it has gone largely unnoticed outside the industry, foreign firms are partnering with American companies to pursue these new possibilities. I expect this new wave of Arctic development will help increase U.S. oil production and influence in world oil markets for at least the next several decades.

This is a global story, spurred by continued growth in world oil demand, especially in Asia; the dynamism of the oil industry; and the fact that the United States has become a major new petroleum exporter, something that would have seemed impossible only a few years ago. Such realities imply that decisions made in Washington, D.C. are far from the only forces shaping U.S. energy and climate change policy.

Fracking Comes to the Arctic Over the past year oil companies have discovered volumes on Alaska’s North Slope totaling as much as five billion barrels or more of recoverable oil. This is a 14 percent increase in U.S. proven reserves, based on recent estimates, which is no small thing.

One discovery, “Horseshoe,” made this year by the Spanish company Repsol in partnership with Denver-based Armstrong Oil and Gas, is the largest new U.S. find in more than 30 years. It is estimated at 1.2 billion barrels, and comes just after a find by ConocoPhillips in January, called “Willow,” evaluated at 300 million barrels.

Both of these are dwarfed by “Tulimaniq,” a spectacular discovery drilled by Dallas-based Caelus Energy in the shallow state waters of Smith Bay, about 120 miles northwest of Prudhoe Bay, in October 2016. Caelus has confirmed a total accumulation of as much as 10 billion barrels of light, mobile oil, with 3-4 billion barrels possibly recoverable at current prices of about US$50 per barrel.

These new finds may only be the beginning. Tulimaniq will produce from reservoirs of the same age as Horseshoe and Willow, 75 miles to the southeast. This strongly suggests that a large new stretch of the North Slope, mostly on federal land and in state waters (within three miles of shore), has been defined for further exploration. Burgundy Xploration of Houston and Australia-based 88 Energy also have another new drilling program underway to test shale intervals known to have sourced some of the oil at Prudhoe Bay, a supergiant field that has produced some 13 billion barrels to date.

A number of these wells will be fracked using techniques similar to those now employed in the lower 48—the first time this has been done in the Arctic. Though hydraulic fracturing has been utilized here since the 1980s, these operations were much smaller in scale and focused on just one or a few stages (fractured interval), whereas today's wells in North Dakota and Texas involve dozens of stages and thus far larger volumes of water and proppant (sand or ceramic grains).

One or more of the oil-bearing rock units at sites being explored on the North Slope have low permeability, meaning that oil can’t flow within them very well or at all. Company engineers expect that hydraulic fracturing will be able to free such oil so it can be produced. Such has been the result for other shales and low-permeability reservoirs in places like North Dakota and Texas.

The logistics of finding large quantities of water and sand needed for fracking in the Arctic will be challenging, and probably more expensive than similar operations in the lower 48 states. The water will most likely be seawater treated for this specific use. It remains to be seen whether operators will clean, reuse and carefully contain frack water.

Green lights from the Trump administration In another significant find, Italian company Eni has developed an oil field that lies in state waters, and so is not affected by Obama’s drilling ban. But the oil reservoir extends into federal waters of the Beaufort Sea. Called the Nikaitchuq Unit, it lies just west of Prudhoe Bay and is producing around 25,000 barrels per day.

Eni developed this field between 2005 and 2015 using an artificial island to drill horizontal wells in various directions from a single site. The company stopped activity in 2015 when prices collapsed, but intends to drill up to six wells this year. Its leases, which continue north into federal waters, were not automatically canceled by the federal ban, but Eni needs a federal drilling permit and has submitted an application to the Interior Department. The company plans to run a long horizontal well to access the additional oil, thereby avoiding any need for a rig in federal waters.

The Interior Department is now reviewing Eni’s application, which I expect it will approve. Geologic studies indicate that the oil continues across the state/federal boundary, and Eni’s proposal to use a horizontal lateral from an existing drill site appears to be aimed at minimizing environmental impacts.

Moreover, the Trump administration has pledged to promote fossil fuel development. Interior Secretary Ryan Zinke is a former congressman from Montana, which produces oil, gas and coal, and Alaska senators Lisa Murkowski and Dan Sullivan are strong proponents of oil and gas development.

The Oil Industry’s New Dynamics Why is all of this new Arctic drilling happening at a time when oil prices are low and in a place where production costs are high? The oil price collapse that has occurred since mid-2014 is the deepest slump since 1986.

Oil companies have ways of being nimble in hard times, such as selling assets, adjusting production levels and seeking mergers. Now rapid innovations in drilling, seismic imaging and data processing enable well-run companies to cut costs in multiple areas. Some firms can make money today at prices as low as $35 to $40 per barrel or even lower. This includes drilling offshore and fracking onshore.

Innovation and cost-cutting have made U.S. firms a potent global force and eroded OPEC’s dominance by keeping oil supplies high, despite a significant production cut by the cartel and many non-OPEC producers, including Russia. In this new era, smaller companies are making inroads in areas once reserved for giants like BP and Exxon. This shift is significant because smaller, independent companies, for whom new discoveries are especially important, tend to be aggressive explorers.

Oil remains our one unreplaceable energy source. Global mobility and a modern military are, as yet, inconceivable without it. Growth in global demand, centered in developing Asia, will continue for some time, as it did even from 2010 through 2014 when prices were above $90 per barrel.

The United States now exports around 5.7 million barrels per day of crude oil and refined petroleum products, double the level of five years ago and by far the largest volume in our nation’s history, thanks to major increases in sales to Japan, South Korea, India, Taiwan, Singapore and China. In short, we would be expanding fossil fuel production even without a Trump administration.

If these new discoveries become producing fields, the Alaskan Arctic will write a new chapter in the U.S. oil industry’s dramatic ascent. It will increase our leverage over OPEC and may help to counter Russia’s geopolitical influence. This prospect raises a new question: How will we will use our clout as the world’s most important new oil power?

Climate change: Nearly 700 'natural thermometers' demonstrate the world is warmer than its ever been
(Spoiler alert; "ever" means 2000 years)

'You can only be smacked in the face by evidence so many times and not see some kind of pattern,' says scientist

    Scientists have found evidence that wildfires, like this one near Clayton, California, have been getting worse because of climate change Reuters

    Planet Earth is warmer than it has been for at least 2,000 years, according to a study that took its temperature from 692 different “natural thermometers” on every continent and ocean on the planet.

    In the most comprehensive assessment of how the climate has changed over the period to date, researchers looked at a host of sources of historic information, including tree rings, ice cores, lake and sea sediments, corals, mineral deposits and written records.

    What they found confirmed the famous “hockey stick” graph, showing an undulating, but broadly flat, line followed by a sharp uptick that begins at around 1900.

    The only plausible explanation for this sudden change is fossil fuel emissions, which have increased the level of carbon dioxide in the atmosphere from about 280 parts per million in the 19th century to more than 400 today.

    The warming effect was predicted by the Nobel Prize-winning Swedish scientist Svante Arrhenius in 1895.

    Writing in the journal Scientific Data, a team of nearly 100 researchers described how they had created a database of 692 records from 648 different locations in “all continental regions and major ocean basins”.

    Some of these natural thermometers covered the entire 2,000-year period, with an average length of 760 years.

    The original hockey stick graph, which spanned 1,000 years, was widely praised when it was published in the journal Nature 20 years ago, but also came under attack from climate change sceptics and deniers. Professor Michael Mann, one of the paper’s authors, was abused, made the subject of hostile investigations by US politicians, and even sent death threats.



    The original 'hockey stick' graph, published in 1998, showed the global average temperature remains about the same from 1,000 years ago until a sharp rise in the 20thcentury (Mann et al)

    In a blog post about the new study, one of researchers, Professor Julien Emile-Geay, wrote that it essentially confirmed the hockey stick graph was accurate.

    “As a scientist, you have to go where the evidence takes you,” he said.

    “You can only be smacked in the face by evidence so many times and not see some kind of pattern. (You will never guess: a HOCKEY STICK!).

    “The hockey stick is alive and well. There is now so much data supporting this observation that it will take nothing short of a revolution of how we understand all paleoclimate proxies to overturn this pattern. So let me make this prediction: the hockey stick is here to stay.”

    Mr Emile-Geay, of the University of Southern California, said any argument about the basic pattern of warming was over.

    “In the coming years and decades, the scientific community will flesh out many more details about the climate of the past 2,000 years, the interactions between temperature and drought, their regional and local expressions, their physical causes, their impact on human civilizations, and many other fascinating research questions,” he said.

    “But one thing won’t change: the 20th century will stick out like a sore thumb. The present rate of warming and, very likely, the temperature levels are exceptional in the past 2,000 years, perhaps even longer.

    “The hockey stick is alive; long live the hockey stick. Climate denialists will have to find another excuse behind which to hide.”

    While in the US there are leading politicians, including President Donald Trump and Lamar Smith, the chair of the House of Representatives’ Science, Space and Technology Committee, who have claimed climate change is a hoax or a plot to create a world government, the UK’s leading sceptics accept much of the scientific analysis of what has happened so far.

    Lord Nigel Lawson, the former Conservative cabinet minister and founder of the Global Warming Policy Foundation, told a House of Lords’ committee hearing that carbon dioxide was a greenhouse gas that was having “some effect” on the climate.

    Instead, they tend to downplay the future effects with some describing themselves as “lukewarmists”.

    Scientists say this makes the same mistake as those who confidently predict Armageddon. Instead, the future is uncertain, with computer models based on the laws of physics predicting anything from a reasonably “lukewarm” 1.5°C of warming to an “end-of-civilisation-as-we-know it” 5°C if carbon dioxide levels hit double the pre-industrial level of 280 parts per million.

    The Paris Agreement on climate change committed countries to trying to restrict global warming to below 2°C and as close to 1.5°C as possible. There has been nearly 1°C of warming attributed to human activity to date.

    Mr Mann said the new study was “impressive”.

    “The end result of course isn’t too surprising – they get a hockey stick-curve no matter how you slice the data,” he wrote in a direct message on Twitter.

    “As if we needed it, [it is] further confirmatory evidence that the recent warming spike has no precedent as far back as we can go.

    “Human activity is having an unprecedented impact on our climate.”
