Title: Peak oil

Peak oil
Transition Training 2007

Peak oil- What is it?
  • Peak oil is the point at which we can no longer
    increase the amount of crude oil we extract and
    globally petroleum production goes into
    irreversible decline.
  • This typically happens when an oil province has
    extracted roughly ½ of all the oil that is ever
    going to be extracted from that province - it is
    not when the oil runs out.
  • This slide illustrates why the sum total of a
    collection of oil fields in a region when added
    together creates a peak at about the half way
    point in production

Peak oil- What is it? How an oil well works
  • Initially the oil is under pressure and when you
    drill into the oil bearing rock, the pressure
    drives the oil out of the stone and upwards to
    the surface.
  • You can drill several wells into the same field,
    increasing output from that field
  • After a time the pressure begins to fall so
    production falls. To get the last recoverable oil
    out water or gas is pumped into the field

Peak oil- What is it? Oil field production
  • These two large oil fields illustrate the basic
    dynamics of oil production
  • A steep initial increase, a production plateau
    and then a slow but irreversible decline.
  • Once the peak is past there are many techniques
    and technologies that can brought to maximise the
    declining output, but it is a losing battle and
    production will never return to it former levels.

Peak oil What is it? Oil production follows
discovery
  • Oil production peak follows oil discovery peak,
    usually 25-40 years later.
  • This is the time it takes to get production going
    after the initial finding.
  • In country after country and oil province after
    oil province the pattern is broadly the same
    four examples are shown of countries that have
    peaked.
  • Globally we are now discovering 1 barrel of oil
    for every 5 or 6 that we use.

When will it happen? UK Oil production profile
  • This is the pattern in the UK, showing oil
    production from the North Sea.
  • Each coloured band shows a different oil field
  • Britains production peaked in about 2000 and is
    now in steep decline.
  • Britains oil and gas will be virtually gone in
    15 years.

11
Global oil discovery and production
Transition Training 2007
12
When will it happen? Global oil discovery,
production, and demand
  • To produce oil you first have to discover it.
    World discovery peaked in the late 1960s and has
    been falling ever since, and despite rapidly
    improving and sophisticated, technology, there
    is no prospect of it ever increasing.
  • At the same time production has been rapidly
    rising.
  • Demand is projected to go on rising, (with
    production failing to keep up), especially in
    rapidly industrialising countries like China and
    India, and is leading to rapidly rising oil
    prices.

13
When is the global oil peak?
Transition Training 2007
14
When will it happen? When will global oil
production peak?
  • The argument is when will we peak, not whether.
    This graph shows various predictions of the
    global oil peak. They cluster around 2010, with a
    few optimistic analysts, predicting a peak many
    years in the future.
  • Dr James R. Schlesinger, former US Energy
    Secretarystated in 2007, You (peak oilists) are
    no longer the beleaguered small minority of
    voices crying in the wilderness. You are now main
    stream.
  • The predictions are from government bodies like
    the International Energy Agency, oil companies
    like BP, and independent researchers like Chris
    Skrebowski.

Oil producers (98)

When will it happen?Of the 98 producers 64
countries have already peaked
  • There are 98 countries in the word that produce
    oil, some large some small.
  • The countries in red are the countries that are
    now post peak.
  • Their oil production is now in decline and
    nothing they can do will ever reverse that.
  • Of 98 producers 64 have already peaked. Anyone
    who tries to tell you that peak oil is a myth
    should look at one of these countries- not one
    has ever failed to follow the Hubberts peak
    and then decline

17
Exports from oil producers
Transition Training 2007
18
When will it happen? Exports from oil exporting
nations
  • Oil exporting nations are using their oil for
    their own internal consumption at an ever
    increasing rate.
  • Oil is often very cheap, like in Saudi Arabia,
    30p per gallon, so there is no incentive to
    conserve.
  • As their economies are booming, and their
    population is also growing rapidly, this means
    they have less oil to export.
  • Oil export peaked in 2005, and after a short
    plateau, is declining rapidly. This is very bad
    news for countries like the USA which need to
    import 16 million barrels of oil a day.

19
8020 rule
  • The worlds giant oilfields are in steep decline

Transition Training 2007
20
When will it happen?8020 rule decline of the
giant oil fields
  • The 8020 rule is that 80 of your result comes
    from the first 20 of your effort with
    diminishing returns after that
  • In oil terms we find the easy to find and produce
    oil first - the largest oil fields. 50 of global
    oil is produced by the 120 largest oil fields in
    the world (out of over 4000 fields)
  • This graph shows that discovery of giant oil
    fields peaked in the late 1960s. Now we find
    very few giant (greater than 1 billion barrels)
    oil fields, and that rate of discovery is
    declining.

WHERE WE GET OUR ENERGY
Source ExxonMobile web site
22
Why is oil so important?
It is frightening how dependent we are on fossil
fuels. We have only begun the move away from
fossil fuel energy. Even if we were to double
the amount of energy we get from renewables, and
then double it, and then double again, which
would be a heroic achievement, it would still
only create 3 of energy requirements.
23
If peak oil was imminent, what would be the
Canary in the Coal mine?
  • Transition training 2008

24
When will it happen?
  • Light sweet crude peaks first.
  • The worlds largest oil fields peak and decline
  • Countries start to decline.
  • Oil price increases rapidly, and then maybe
    crashes, erratic behaviour.
  • Exports from oil producers peaks
  • Oil producer countries take control of their
    resources.
  • .......all this has happened, and has
    accelerated, in the last 5 years

25
Why is oil so important? How many men does it
take to push a car?
Transition Training 2007
26
Why is it so important? The phenomenal energy in
petrol
  • A tank of petrol contains 8,000 human hours work!
  • If you worked for 8 hrs/day, 52 weeks a year, 7
    days a week that equates to about 3 years work.
  • Most of us take for granted the amount of energy
    we have at our disposal instantly, everyday. No
    human society had anything near the amount of
    energy before the discovery of fossil fuels.

27
What do we use oil for?
Transition Training 2007
28
Why is oil so important?What do we use oil for?
  • Our entire way of life, and a bewildering array
    products are reliant on oil.
  • Transport is only the beginning of our oil use.
  • Many products are derived from, or use oil or gas
    as their raw material. Plastics, synthetic
    fibres, drugs, laminates, paints, ink the list
    is endless
  • The so called Green revolution , modern
    agriculture depends on oil. Fertilisers and
    pesticides are made from oil and natural gas,
    tractors and machinery use it, irrigation
    requires huge amounts of energy and this is
    before food miles, processing, and storing,
    cooking, and packaging and retailing are taken
    into account.
  • Industry and even the service sector use huge
    amounts of energy.

29
No country has yet decoupled economic growth from
energy use
Transition Training 2007
30
Why is oil so important?
  • Economic growth requires growth in our energy
    supply.
  • We have an economic system that is dependent on
    growth.
  • Therefore we are dependent on increasing supplies
    of energy.
  • All forecasts of economic growth also show rising
    energy demand.
  • When peak oil arrives we will have less total
    energy so economic growth will slow and probably
    decline, perhaps permanently

31
The carbon cycle
1
Transition Training 2007
32
The active carbon cycle
  • The carbon dioxide cycle is a natural one ,and
    one that has been in dynamic balance and
    undergone many fluctuations and cycles over
    millions of years.
  • There is a balance between the seas and the land
    and the atmosphere. Carbon is locked up in the
    seas in plankton and other marine life, and
    dissolved in the water. Carbon is also locked up
    in plant matter on the earth (active carbon
    cycle), and in fossil deposits (inactive carbon
    cycle) of oil, natural gas, and coal.
  • The destabilising factor in the carbon cycle is
    that we have taken the locked up (inactive)
    carbon from fossil fuels and put that carbon in
    the atmosphere. The land and the sea carbon sinks
    are unable to absorb this excess carbon.

33
What is climate change?
2
Transition Training 2007
34
Define Climate Change The term "climate change"
is sometimes used to refer to all forms of
climatic inconsistency, but because the Earth's
climate is never static, the term is more
properly used to imply a significant change from
one climatic condition to another.
What is causing Climate change or Global
Warming? Rising human made CO2 concentrations in
the atmosphere.
It this a theory? Yes
Why? Because it is trying to establish two cause
and effects. Firstly that CO2 is the cause of
global warming and secondly that humans are
causing it through the burning of fossil fuels.
35
Is it proven?
3
Transition Training 2007
36
  • Have both cause and effects been proven? Is
    the earth warming, and are humans causing it?
  • Main Point
  • Yes, as much as a scientific theory can be
    proven. It It has been confirmed by the
    International Panel for Climate Change is a
    worldwide group of scientists who have reviewed
    all available scientific research.
  • Detail
  • The 4th IPCC report published in 2007 states,
  • 1-Warming of the climate system is unequivocal.
  • 2-Most of the observed increase in globally
    averaged temperatures since the mid-20th century
    is very likely (confidence level gt90) due to the
    observed increase in human greenhouse gas
    concentrations.
  • This is scientific speak for yes!
  • This United Nations study, which was just awarded
    the 2007 Nobel peace prize, was the most
    comprehensive study of peer reviewed climate
    research ever undertaken, and one of the most
    comprehensive studies of any scientific question
    ever. Its conclusions are that there is no more
    debate, the science is clear. The only question
    is how fast can we act to create real reductions
    in atmospheric CO2.

What are the main problems with out of control
CC?

Transition Training 2007

What are the main problems with out of control CC?
  • Main Points
  • Severe one in a hundred year weather events
    becoming common
  • Sea level rises, leading to increasing land loss
    and cc refugees
  • Species loss
  • Additional Points
  • Increased droughts/desertification. This slide is
    of the Australian Murray River system, which has
    faced an extreme multi year drought. The
    government has had to take the decision to
    allocate whatever water there is to the cities
    rather than allow farmers to irrigate their
    crops. This has lead to a decrease in the
    Australian wheat harvest of 35 this year.
    Australia is one of the bread baskets of the
    world.
  • Increased floods- like this year in the UK.
  • Acidic seas
  • Species loss due to temperature zones migrating _at_
    the rate of 2km/yr. This will accelerate species
    loss due to habitat loss, as many species of
    plants and animals will be unable to migrate with
    the temperature. We face a potential of 50 or
    more loss of life on earth. We are depended on
    the web of life for our survival.

CO2 levels over the past 60000 years

381 ppm 2006

Transition Training 2007

The natural carbon cycle and human effects
  • Main points
  • This shows the ice core data measuring
    atmospheric CO2 concentrations over the last
    60,000 years. As you can see CO2 levels have
    risen and fallen. To keep the climate from
    warming more than 2 degrees C we would have to
    keep CO2 concentration to below 450ppm
  • They are currently at 380ppm without counting the
    other GHG which are Methane, nitrous oxide, CFCs.
  • Additional Points
  • The last ice age ended 20,000 years ago and lead
    to a rise in CO2, and if we went back a few
    100,000 years we would see this pattern of rise
    and fall. What happens next (in red) shows the
    result of a new agricultural system, and human
    population increase, and then the green shows the
    beginning of the industrial era and the burning
    of fossil fuels. The orange is the 20th 21st
    century.

41
The need for an urgent response
6
Transition Training 2007
42
  • The need for an urgent response
  • Once global temperatures rise to certain levels
    positive feedback loops will cause further
    releases of greenhouse gases, leading to runaway
    climate change
  • On the best evidence we need to keep temperature
    rises to less than 2 C.
  • Emissions already made have not yet had their
    full impact so we are perilously close to
    reaching this even if we reduce emissions
    dramatically now.
  • Positive Feedback loops
  • For example if the arctic tundra melts it will
    emit so much methane, a powerful green house gas,
    that it will dwarf human CO2 emissions.

Responses to Peak Oil Climate Change
7
  • PEAK OIL
  • Burn everything!
  • relaxed drilling regulations
  • biofuels
  • tar sands and non-conventional oils
  • Resource nationalism
  • Resource Wars
  • CLIMATE CHANGE
  • Climate engineering
  • Carbon capture and storage
  • International emissions trading
  • Climate adaptation
  • Nuclear power
  • P O C C
  • Systems Re-think
  • Planned Relocalisation
  • Energy Descent Pathways
  • Local Resilience

44
Response to PO and CC
  • Looking at peak oil alone you look for
    replacements tar sands, remote fields such as
    the antarctic, bio fuels, coal to liquids.
  • If we dont reduce oil dependency in rich
    countries there will inevitably be either climate
    disaster from replacements or resource wars.
  • Looking at climate change alone you may look for
    energy intensive solutions to mitigate climate
    change, including nuclear.
  • When PO and CC are taken together you have to
    redesign the system a low energy, re-localised
    and resilient system is the only viable future.
