  2. Extraction of petroleum - Wikipedia

    en.wikipedia.org/wiki/Extraction_of_petroleum

    Tertiary recovery begins when secondary oil recovery is not enough to continue adequate extraction, but only when the oil can still be extracted profitably. This depends on the cost of the extraction method and the current price of crude oil. When prices are high, previously unprofitable wells are brought back into use, and when they are low ...

  3. Oil shale economics - Wikipedia

    en.wikipedia.org/wiki/Oil_shale_economics

    Oil shale economics deals with the economic feasibility of oil shale extraction and processing.Although usually oil shale economics is understood as shale oil extraction economics, the wider approach evaluates usage of oil shale as a whole, including for the oil-shale-fired power generation and production of by-products during retorting or shale oil upgrading processes.

  4. Enhanced oil recovery - Wikipedia

    en.wikipedia.org/wiki/Enhanced_oil_recovery

    Adding oil recovery methods adds to the cost of oil—in the case of CO 2 typically between 0.5–8.0 US$ per tonne of CO 2. The increased extraction of oil on the other hand, is an economic benefit with the revenue depending on prevailing oil prices. [39]

  5. Solar thermal enhanced oil recovery - Wikipedia

    en.wikipedia.org/wiki/Solar_Thermal_Enhanced_Oil...

    According to research analysts at Raymond James, solar EOR can be done more cost effectively than using gas, even as current depressed prices. Steam represents as much as 60 percent of the production cost for heavily oil extraction. [12] In addition to being cost competitive with gas, solar EOR provides a hedge against long-term gas price ...

  6. Steam injection (oil industry) - Wikipedia

    en.wikipedia.org/wiki/Steam_injection_(oil_industry)

    Finally, the hot oil is pumped out of the well for a period of weeks or months. Once the production rate falls off, the well is put through another cycle of injection, soak and production. This process is repeated until the cost of injecting steam becomes higher than the money made from producing oil. [3]

  7. Price of oil - Wikipedia

    en.wikipedia.org/wiki/Price_of_oil

    Oil traders, Houston, 2009 Nominal price of oil from 1861 to 2020 from Our World in Data. The price of oil, or the oil price, generally refers to the spot price of a barrel (159 litres) of benchmark crude oil—a reference price for buyers and sellers of crude oil such as West Texas Intermediate (WTI), Brent Crude, Dubai Crude, OPEC Reference Basket, Tapis crude, Bonny Light, Urals oil ...

  8. Shale oil extraction - Wikipedia

    en.wikipedia.org/wiki/Shale_oil_extraction

    Shale oil extraction is an industrial process for unconventional oil production. ... These industries continued until oil prices fell sharply in the 1980s. [9] [12] ...

  9. Peak oil - Wikipedia

    en.wikipedia.org/wiki/Peak_oil

    Peak oil relates closely to oil depletion; while petroleum reserves are finite, the key issue is the economic viability of extraction at current prices. [6] [7] Initially, it was believed that oil production would decline due to reserve depletion, but a new theory suggests that reduced oil demand could lower prices, impacting extraction costs.
