Geopolitical risks to US oil supply lowest since the early 1970s

by Rice University, January 5, 2018 in Sciencedaily


The geopolitical risks to the United States’ oil supply are the lowest since the early 1970s, due to fracking, climate action and a more diverse global supply, according to a new paper. America’s energy prosperity contrasts with a more fraught period for energy-exporting countries where geopolitical challenges have been compounded by fiscal stress and rising domestic energy demand, the authors said.

Secretary Zinke Announces Plan For Unleashing America’s Offshore Oil and Gas Potential

by Press Release, U.S. Department of the Interior, January 1, 2018


 U.S. Secretary of the Interior Ryan Zinke today announced the next step for responsibly developing the National Outer Continental Shelf Oil and Gas Leasing Program (National OCS Program) for 2019-2024, which proposes to make over 90 percent of the total OCS acreage and more than 98 percent of undiscovered, technically recoverable oil and gas resources in federal offshore areas available to consider for future exploration and development. By comparison, the current program puts 94 percent of the OCS off limits. In addition, the program proposes the largest number of lease sales in U.S. history.

U.S. oil production booms as new year begins

by Thomas Heath, December 31, 2017 in Washington Post


U.S. crude oil production is flirting with record highs heading into the new year, thanks to the technological nimbleness of shale oil drillers .

The current abundance has erased memories of 1973 gas lines, which raised pump prices dramatically, traumatizing the United States and reordering its economy. In the decades since, presidents and politicians have made pronouncements calling for U.S. energy independence.

IEA sees Southeast Asia oil demand growing until at least 2040

by Florence Tan, October 26, 2017 in Reuters


SINGAPORE (Reuters) – Southeast Asian demand for oil will keep growing until at least 2040 as emerging nations there rely on the fossil fuel to transport their rapidly growing populations, ship goods and make plastics, the International Energy Agency said on Tuesday.

Oil usage in the region will expand to around 6.6 million barrels per day by 2040 from 4.7 million bpd now, with the number of road vehicles increasing by two-thirds to around 62 million, the agency said in a report. It did not make any forecasts beyond 2040.

Thanks to Shale, U.S. CO2 Emissions Continued to Decline in 2016

by Nicole Jacobs, October 3, 2017 in ClimateChangeDispatch


The report, which bases its CO2 emissions estimates off International Energy Agency (IEA) and BP data through 2016, found the global CO2 levels essentially remained flat in 2015 and 2016. As BP noted earlier this year, the global trend is “well below the 10-year average growth of 1.6% and a third consecutive year of below-average growth” and that “during 2014-16, average emissions growth has been the lowest over any three-year period since 1981-83.”

Les chiffres clés de l’énergie dans le monde

by Connaissance des Energies, 26 septembre 2017


Les énergies fossiles toujours omniprésentes dans le mix mondial

La consommation mondiale d’énergie primaire a encore reposé à 81,4% sur les énergies fossiles en 2015 selon les dernières données de l’AIE. En 1973, cette part atteignait 86,7% (dont 46,2% pour le seul pétrole) et les énergies décarbonées ont ainsi légèrement progressé dans le mix énergétique mondial.

Notons que les productions mondiales de gaz naturel et de charbon ont respectivement triplé et plus que doublé depuis 1973. Les émissions mondiales de CO2 relatives à la combustion d’énergie ont pour leur part doublé durant cette période.

‘Game-Changing’ new research on prolific Permian Basin estimates 60 billion to 70 billion barrels remain, IHS Markit says

by PennEnergy Editorial Staff, September 25, 2017


Energy researchers at IHS Markit have completed the first, three-year phase of a massive Permian Basin research project that models and interprets the giant basin’s key geologic characteristics to better estimate its remaining hydrocarbon potential, and initial results indicate the giant basin still holds an estimated 60 billion to 70 billion barrels of technically recoverable resources.
To conduct this new analysis, researchers used the IHS Markit historical well and production database that includes more than 440,000 Permian Basin wells, and a new proprietary software tool that, for the first time, enables them to leverage interpreted formation ‘tops’ data to identify accurate formations for completion intervals on hundreds of thousands of wells

Techniques d’exploitation des mines de charbon

by Connaissance des Energies, 16 mars 2015


Les gisements sont des zones généralement profondes où l’on trouve de grandes quantités de charbon. Il faut forer des puits pour y accéder et extraire le minerai. Lorsque les réserves de charbon sont relativement proches de la surface de la terre, une exploitation à ciel ouvert peut être mise en place. Il existe également des gisements de charbon sous les océans, pour le moment inexploités.

Is the world warming to clean coal?

by Sebastien Laye, September 18, 2017 in NotaLotofPeopleKnowThat


Those voices are the impetus behind what Subramanian calls a “green and clean coal coalition” spanning both the developed and developing worlds. Emerging markets in Asia and Africa will continue to build new coal-fired power stations for at least the next two decades. In that timeframe, coal-fired solutions are indispensable to meeting their demands for electrification and growth. As clean coal solutions emerge, new plants in the developing world can and should be far cleaner than previous generations of coal-fired plants in Europe and America.

La revanche des pétroles de schiste

by Connaissance des Energies, 18 septembre 2017


Après avoir vu leur production tripler entre 2010 et 2014, les « light tight oil » américains (LTO), fréquemment appelés « pétroles de schiste », ont fait preuve d’une résilience étonnante lors de la chute des prix. Ils surprennent aujourd’hui à nouveau les marchés et pourraient contrarier la stratégie de l’OPEP.

Dans cette étude publiée par le Centre Énergie de l’Ifri, Sylvie Cornot-Gandolphe (voir le .pdf ci-dessous) présente les grands changements du secteur des LTO américains au cours des dernières années en expliquant leur résilience lors de la chute des cours et leurs perspectives de croissance.

Toujours plus d’énergie et un mix quasiment inchangé en 2040 ?

by Connaissance des Energies, 15 septembre 2017


La consommation mondiale d’énergie pourrait augmenter de 28% entre 2015 et 2040 selon les dernières prévisions de l’EIA (agence américaine d’information sur l’énergie) présentées hier. Le mix énergétique mondial devrait pour sa part rester très largement dominé par les énergies fossiles dans les décennies à venir.

EIA: World energy consumption to increase 28% by 2040

by Oil&Gas Journal Editors, September 14, 2017


World energy consumption is projected to rise to 736 quadrillion btu (quads) in 2040 from 575 quads in 2015, an increase of 28%, according to the latest International Energy Outlook 2017 (IEO2017) from the US Energy Information Administration.

Most of this growth is expected to come from countries that are not in the Organization for Economic Cooperation and Development and especially in countries where demand is driven by strong economic growth, particularly in Asia. Non-OECD Asia, which includes China and India, accounts for more than 60% of the world’s total increase in energy consumption from 2015 through 2040.

Carbon dioxide emission-intensity in climate projections: Comparing the observational record to socio-economic scenarios

by F. Pretis and M. Roser, June 2017, Energy, Elsevier


 

The wide range of socio-economic scenarios in climate projections results in high uncertainty about climate change.

We compare socio-economic scenario projections to observations over 1990–2010.

Global CO2 emission intensity increased despite all major scenarios projecting a decline.

Under-projection of emission intensity raises concerns about achieving emission targets.

 

The State of Global Shale

by The American Interest, September 6, 2017


While the United States gears up for what is expected to be a record-breaking production year in 2018, the rest of the world remains far away from catching up to America’s runaway shale success. But while the U.S. may be the only country producing commercially significant volumes of shale today, it’s not the only one with sizable shale reserves—according to the U.S. Energy Information Administration, Argentina, Algeria, and China all have more shale gas than the United States, and Russia has nearly as much tight oil

Can Oil Sands Pay Off at Just $50 a Barrel?

by Kevin Orland, August 24, 2017 in BloombergNews


Canada’s tar sands, which contain the planet’s third-largest oil reserves, were a prized possession for global energy companies when crude was trading above $100 a barrel. But since prices fell to $50 in 2015, where they have lingered, Royal Dutch Shell, ConocoPhillips, and Marathon Oil have unloaded their holdings amid concerns that these capital-intensive projects would struggle to turn a profit.

(…) In recent earnings announcements, Suncor and rival Cenovus Energy Inc. said they can now sustain production with oil at $40 a barrel without jeopardizing the dividend they pay shareholders.

Natural Gas Looks Hurricane-Proof, for Now

by Nathaniel Bullard, September 1, 2017 in BloombergView


Since 2005, the U.S. has added more than 120,000 gas wells, mainly in Texas, Pennsylvania, Oklahoma and Colorado. In 2015, there were 555,000 in total.

Those onshore wells have not just made up for declining offshore production, they have handily exceeded it. Offshore gas is now only 4 percent of total U.S. withdrawals. Texas, Pennsylvania, Oklahoma and Colorado are 53 percent of all production.

Quantifying the causes of the recent decrease in US CO2 emissions

by Roger Andrews, August 23, 2017 in Energy Matters (blog)


Between 2007 and 2015 total annual US CO2 emissions decreased by 740 million tons (12%). An updated analysis shows that 35% of this decrease was caused by natural gas replacing coal in electricity generation, 30% by lower fuel consumption in the transportation sector, 28% by renewables replacing
