Study Notes

Earth Systems Engineering - APSC 151 2024

  • The course covers Earth Systems Engineering, specifically focusing on energy resources like hydrocarbons (oil, gas, and coal).
  • Fossil fuels in Canada include large quantities of petroleum, gas, and coal, which are mostly exported.
  • Petroleum comes from southern areas of the Prairie provinces, as well as offshore petroleum deposits in Newfoundland, Labrador, Yukon, and Northwest Territories, Nunavut.
  • Natural gas is produced in the prairies and southern Ontario (Lake Erie).
  • Coal is mined in British Columbia, Alberta, and Nova Scotia, mainly for steel production.
  • CO2 emissions by type in the USA have shown substantial increases since the late 1700s.
  • Coal is formed from the burial and decomposition of plant material in swamps, occurring in oxygen-poor depositional environments during the Carboniferous Period.
  • Coal seams are layers of varying levels of alteration (peat > lignite > bituminous > anthracite).

Hydrocarbons

  • Hydrocarbons are formed by the "cooking" of simple aquatic organisms in source rocks.
  • Kerogen is formed initially, with rising temperatures causing cracking of carbon-carbon bonds.
  • This process creates oil and subsequently wet gas from dry gas (methane) above 150°C.
  • Crude oil is refined through distillation into various fractions (e.g., gases, light naphtha, heavy naphtha, kerosene, light gas oil, heavy gas oil, residuum).
  • Cracking is used to break down larger hydrocarbons into smaller ones, producing a range of useful products like gasoline.

Petroleum Migration

  • Petroleum fluids are mobile and less dense than water, migrating upwards.
  • They reach the surface unless trapped within subsurface structures.
  • Traps are crucial regions that prevent hydrocarbons from escaping.

Petroleum Traps

  • Common traps include domes and anticlines, which are doubly plunging structures.
  • There are also stratigraphic and structural traps like fault traps and salt domes.

Oil Sands

  • Are unconventional fossil fuel deposits
  • Consist of mixtures of sediment, water, and bitumen (a viscous black tar-like substance).
  • The vast Athabasca tar sands in Alberta contribute significantly (15%) to Canada's oil production.
  • Refining oil from these sands is costly.

Oil Shale

  • Another unconventional fossil fuel; it is not shale itself, but fine grained limestone.
  • Contains enormous amounts of kerogen, which must be heated to release the petroleum.
  • The extraction process often requires "fracking".

Shale Gas

  • Primarily methane trapped in pores and fractures of shale, or other fine-grained sedimentary rock.

Fracking

  • Hydraulic fracturing (fracking) breaks up shale rock for gas extraction.
  • Water, sand, and chemicals are injected at high pressure to create fractures.
  • Natural gas is released through these created fissures.

Oil Transport

  • Oil is transported via trains, pipelines, and ships.
  • Different modes of transport have varying safety records.

Global Oil Trade

  • Ships carry large amounts of oil globally.

Global Warming

  • Fossil fuel emission increases the concentration of CO2.
  • This leads to global warming, a significant increase in surface temperature since the early 20th century.
  • Canada's emissions and projected emission reductions are considered.

Seismic Exploration

  • Using seismic waves to study the subsurface.
  • Used to explore for subsurface resources, especially oil and gas.

Offshore Exploration

  • Oil exploration and extraction in offshore environments.
  • Often involves specialized rigs and deep-sea operations.
