Q

Outline some physical risks to resource security

A
  • Global commons (resource frontiers) will be exploited
  • Population grows, more resources (water, oil, gas and food) will be used, causing increased GHG emission/pollution (for every 1 barrel of oil we fine, we use 3)
  • Industrialising countries increasing their production of fossil fuels and energy intensive industries

Q

Outline some geopolitical risks to resource security - give an examples

A

Conflicts in Libya and Iraq have hit production in these countries. A further concern might be the diplomatic relations with certain countries

Both Russia and Iran have recent histories of trade embargoes placed on them by Western countries, including oil and gas exports

Climate change concerns and green policies being ignored

Russia’s influence over European countries due to their control of gas exports. Russia has stopped its exports of gas to Ukraine to exert influence over political matters

Cartels controlling the production of commodities to influence the price and maximise profit. In 2016 OPEC members agreed to cut their production of oil to help raise its falling price

Q

Critical - Give examples

A

Resources that require careful management by human society in order to ensure their continuous availability. If they are exploited too intensively to the extent that they can no longer be renewed, then they become stock (non-renewable) resources.

For instance, overfishing can become unsustainable, leading to the fish population no longer being able to reproduce at a rate required to maintain fish stocks into the future

Q

Non-critical: Give examples

A

These resources have taken millions of years to form and so they are finite (can be exhausted), which is why we call them non-renewable. They are not going to be replenished in the near future. For example, coal or gas is created over millions of years so is not useful on a human timescale. Some stock resources may have their exploitable life extended through recycling such as copper, while others are consumed in a single use

Q

Conventional oil reserves:

A

Traditional methods of getting out oil such as oil drilling with large oil rigs which extract oil from large pools. The natural pressure from the well is all it takes to pump this oil to the surface

Q

Unconventional oil reserves

A

Oil that is obtained without using the traditional method. For example, Sediments like sandstone are formed in layered deposits. Instead of a pool, oil in these layers is spread out in small amounts. To reach the dispersed oil, horizontal drilling is used to go into the layer. One method is hydraulic fracturing, used to create cracks in this rock to allow for oil flow

30
Q

What is the McKelvey box and what does it show?

A

A diagram that shows the difference between resources and reserves. As one travels from resources to reserves, both geologic certainty and economic feasibility increase

31
Q

Possible resources:

A

Possible resources are minerals which are thought to exist based on limited locational knowledge and exploration, thus the quantity and quality is known with the least confidence of any of the categories. Possible resources can be referred to as hypothetical or speculative

32
Q

Hypothetical resources -

A

are those in regions where mining/drilling takes place but haven’t yet been discovered, but they are anticipated to exist due to particular geological conditions similar to those where they have been seen

33
Q

Speculative resources -

A

are predicted resources in regions where no extraction currently takes place

34
Q

Inferred resources:

A

Are the part of a mineral resource for which quantity, grade and mineral content can be estimated with a low level of confidence. It is inferred from limited geological evidence and assumed but not verified geological or grade continuity

35
Q

Indicated reserve:

A

Economic mineral occurrences that have been sampled to a point where an estimate has been made, at a reasonable level of confidence of their contained grade and physical characteristics

36
Q

Measured reserve:

A

Are indicated resources that have undergone enough further sampling that a geologist has declared them to be an acceptable estimate, at a high degree of confidence of the grade and physical characteristics

37
Q

What is the Hubbert curve?

A

Is a method for predicting the likely production rate of any finite resource over time. When plotted on a chart, the result resembles a symmetrical bell-shaped curve. The top of the curve shows peak production and later a secondary peak. The theory was developed in the 1950s to describe the production cycle of fossil fuels

38
Q

What are the stages of the Hubbert curve?

A
  • Cumulating reserves
  • Proven reserves
  • Peak
  • Decline of reserves
  • Secondary peak
39
Q

What is the resource peak?

A

When a maximum rate of resource exploitation is experienced. It occurs just after peak discovery and peak production is able to occur. It referred to US oil production and forecast that oil production would peak in the late 1960s; a prediction that showed high accuracy in the event

40
Q

Why is there often a second peak on the Hubbert curve?

A
  • Technological advancements
  • Unconventional sources being explored/exploited
  • New techniques being used or surrounding area being exploited
  • As more countries are industrialising so are exploring their primary resources
41
Q

When did the following predict peak oil and why? [6]

Hubbert:

International Energy Agency:

Association for the study of peak oil and gas:

A

Hubbert:

1960s

International Energy Agency:

2030

Association for the study of peak oil and gas:

2006

42
Q

What are the five steps in the process of resource development?

A

Exploration - geoscience surveys

Discovery - investment and planning

Development - raising capital and construction

Production - extraction and secondary processing

Reclamation - closure of operation and mitigating against environmental damage

43
Q

what are the three methods of oil recovery

A

Primary
Secondary
Tertiary

44
Q

Primary

A

Primary recovery is the first stage involved in extracting oil and gas. It relies on the natural difference in pressure between the surface and the underground reservoir, therefore requiring relatively limited capital investment

45
Q

Secondary

A

Techniques include adding additional water injections which seek to force oil to the surface by directly applying pressure

46
Q

Tertiary:

A

Involves altering the properties of oil to assist in its extraction such as make it less volicious by using heat, gas and chemical injections. Its more expensive and uneconomical

47
Q

How dependent are EU countries on Russian gas?

A

Some Bultic countries such as Estonia rely 100% on Russia for their gas. Other countries, due to this such as France who don’t have any resources to exploit for themselves, are diversifying their energy mix to include nuclear power. So they are less dependant on Russia

48
Q

What were the recent Russia/Ukraine disputes caused by?

A

Ukraine relied on Russia for half its gas supplies. Ukraine failed to pay off their debts to the government-run company Gazprom which Gazprom delayed when they were pro-Russia but demanded back when Ukraine sided with Pro-west rebels in 2006

49
Q

What is OPEC?

A

Organization of the Petroleum Exporting Countries. Made up of 13 mostly Middle Eastern and North African nations. They are a cartel who fix prices and production to control their profits. They produce 40% of the world’s total crude oil production

50
Q

What are the three aims of OPEC?

A
  • To coordinate and unify its members
  • Ensure the stabilization of oil markets in order to secure an efficient, economic and regular supply of petroleum to consumers
  • Providing a steady income to producers and a fair return on capital for those investing in the petroleum industry
51
Q

Give one example of how OPEC has influenced global energy security

A

In 1973 oil crisis - Arab countries disputes over US involvement Israel war so OPEC cut off all supplies to US and allies causing their energy prices to quadrupled

In 2016, they agreed to limit the number of million barrels they will produce to raise prices

OPEC+ controls over 50% of global oil supplies and about 90% of proven oil reserves

52
Q

Give three factors that limit OPEC’s global influence

A
  • Non-OPEC countries such as Russia and US are producing more oil/gas through unconventional methods thus creating more competition
  • Different domestic politics in OPEC - means there’s internal disputes (Iraq/Iran)
  • Globally, oil prices are going down due to China’s development going down and their trade war with US
  • People are starting to consume more renewable local energy
53
Q

Define resource frontier

A
  • An area on the periphery of a country which is being opened up for resource extraction as older, more accessible resource locations become exhausted
  • Natural harsh environments with little or no human development
  • High infrastructural, extraction, production and transporting cost
  • Lack of technology to exploit legally, politically and economically feasible whilst making a profit
54
Q

What is ANWR?

A
  • Arctic National Wildlife Refuge
  • Located in the Arctic in Alaska
  • A ban on drilling here was signed in the 1980s but was changed in 2015 with President Trump opening up area 1002 for drilling
  • Much of the Arctic Circle falls into the territories of five regional countries: the USA, Canada, Russia, Norway and Denmark (via its ownership of Greenland)
55
Q

Give three reasons why ANWR was not exploited in the past?

A
  • Has a treaty banning drilling on it
  • Isolated making transport, production and construction unfeasible
  • Owned by many countries, so its politically risky
56
Q

Give 3 advantages for exploiting oil resources in ANWR

A
  • Reduce expenditure on oil exports for US
  • Increase energy security
  • Create more jobs for Alaskan people
57
Q

Give 3 disadvantages of exploiting oil resources in ANWR

A
  • Rare birds and Karabue will be displaced
  • Indigenous tribes food source will become more limited
  • High cost of oil extraction makes it not worth it
58
Q

Give three reasons why exploitation of resource frontiers may be more necessary in the future

A
  • Increasing demand due to growing population
  • Depleting resources led to more unconventional resources being exploited due to enhanced technology (methods of extraction and transportation)
  • Climate change will expose more resource frontiers, making them accessible and profitable to exploit
59
Q

Give some reasons why exploitation of resource frontiers may NOT be necessary in the future

A
  • More people will use renewable resources
  • Our consumption or population will decrease
  • Due to the effects of climate change, more legislation will be placed to protect theses areas
  • Our technology may have not catched up to being able to extract from these places
  • As conventional resources deplete, exploiting places will become more politically charged; done at the risk of causing a conflict
60
Q

Give four environmental impacts of oil exploitation in Prudhoe Bay

A

-The tundra contains lots of carbon which will be released
-Plants could have medical properties
-Disrupt bowhead whales
Gas flaring releases nitrous dioxide

61
Q

Prudhoe Bay - give three environmental impacts of the Trans-Alaskan pipeline

A
  • The pipe can leak without being noticed for months
  • Oil spills through ship transport
  • High freshwater use - depletes lakes so much that they freeze permanently causing underwater marine deaths
62
Q

Prudhoe Bay - give some environmental impacts of roads for oil transportation

A

Construction of roads less to standing waters which attracts mosquitoes
Cause noise pollution
Dust from US trucks settle on plants so they can no longer photosynthesis

63
Q

What was the Exxon Valdez disaster?

A

An oil tanker owned by Exxon Shipping Company sank in 1989 which spilled tonnes of oil into Alaska’s seA

64
Q

How did it impact the environment?

A

Sea otters, seas and birds died in the days after

65
Q

What is sustainable resource development?

A
  • Limiting environmental impacts (doing an EIA)
  • Resources being produced in a way that it benefits a place locally, economically and socially (investing in social infrastruture)
  • Develop at a stable rate and for the long term
66
Q

Give 3 examples of

Supply-side management:

A
  • Increasing or decreasing supply
  • Exploring new areas for resources
  • Keeping resources in the ground
67

Introducing alternatives such as supplying renewable energy companies or park and ride schemes

68
Q

What is an Environmental Impact Assessment?

A

Is a process of evaluating the likely environmental impacts of a proposed project, taking into account inter-related socio-economic, cultural, environmental and human-health impacts, both beneficial and adverse

69
Q

What are the stages in an Environmental Impact Assessment (EIA)?

A
  • Screening - authorities demanding an EIA
  • Scooping - identify issues with project
  • Accessing - accessing issues
  • Mitigation - mitigate issues
  • Monitoring - monitoring compliance with local legislation of the mitigation measures
  • Reporting and reviewing - publishing they EIA and preparing for approval/appel
70
Q

Give two examples of an environmental impact identified by an EIA and how they have been mitigated - Lumwana Copper Project, North West Gambia

A

Land degradation - they planted flora after project

Benefit local community - employ many locals, provided clinics, schools, power and water
