Fluid injection can occur with conventional oil and gas extraction methods, which extract fuel from underground pools, and with unconventional methods like fracking, which recover oil and gas from small voids in rocks.

They looked both at wells used for enhanced oil recovery — in which fluid is injected to flush lingering oil from a depleted reservoir — and at those used to dispose of wastewater from conventional oil and gas extraction or from hydraulic fracturing (fracking).

But its supply of conventional oil is shrinking, and oil sands extraction has been growing fast in the past decade, from about 700,000 barrels per day in 2000 to 1.7 million today.

Marshall said as things stand, 51 percent of all oil production in the state is through «tertiary» mechanisms, or enhanced recovery methods targeted in the proposed ban as opposed to conventional forms of extraction.

Separate production models were developed for mining (coal and unconventional oil) and field (gas and conventional oil) operations, which reflected the basic differences in extraction and processing techniques.

On the contrary, Figure 1 is a conservative estimate of potential emissions from tar sands because: the economically extractable amount grows with technology development and oil price; the total tar sands resource is larger than the known resource, possibly much larger; extraction of tar sands oil uses conventional oil and gas, which will show up as additions to the purple bars in Figure 1; development of tar sands will destroy overlying forest and prairie ecology, emitting biospheric CO2 to the atmosphere.

AND as fracking begins to overtake conventional extraction methods and promise us centuries of cheap fossil gas and oil, we're only beginning to understand its impact on water and communities.

We have two main concerns: the risk of oil spills along the pipeline, which would traverse highly sensitive terrain, and the fact that the extraction of petroleum from the tar sands creates far more greenhouse emissions than conventional production does.

If combustion of the final products is included, the so - called «Well to Wheels» approach, oil sands extraction, upgrade and use emits 10 to 45 % more greenhouse gases than conventional crude.

WWF says reductions of 85 % would be required to reduce the emissions from tar sands extraction to be comparable to conventional oil production.

The region has the capacity to produce 2.5 million barrels of oil per day — and in the process, as TreeHugger has explained before, extraction produces up to eight times the emissions of conventional oil and operators are allowed to use twice the amount of fresh water that all of Calgary uses in a year.

This first step of tar sand extraction is estimated to result in gasoline that carries a burden of «at least five times more carbon dioxide» then would conventional «sweet crude» oil production.

Because the extraction of bitumen from those sands is an energy - intensive process, it emits more greenhouse gases than the extraction of oil from conventional reservoirs.

But producing oil sands is a messy, emissions - intensive business; according to the U.S. Environmental Protection Agency, the extraction process produces 82 percent more emissions than conventional oil drilling.

Van der Veer went on to claim that the «well - to - wheels» carbon footprint of Canadian tar sand extraction — in which Shell is heavily invested, seeing 74 % profit growth in the second quarter of this year — was only 15 % higher than conventional sources of oil.
