Document Summary

Fossil fuels and the future of oil (ii) Secondary extraction: not gushing out under own power for some reason, need to inject something into it, sea water, gas, etc, loosen up oil and allow it to be extracted. A lot of it takes place offshore. Takes place on shallow marine environment seafloor. Natural gas tends to occur with oil. 25% of commercial energy consumption liquefied natural gas liquid can be shipped long distances in refrigerated tankers. Canada is world"s third-largest producer of natural gas. Pipelines in news are little connectors to old pipelines. Thermogenic gas: results from compression and heat deep underground. Biogenic gas: created at shallow depths by bacterial anaerobic decomposition of organic matter, ex. Landfills a lot of organic matter collecting. Source material is organic matter that results when carbon bonds begin breaking down: called kerogen. Most remaining fields require pumping by horsehead pumps.
