  2. Pseudofossil - Wikipedia

    en.wikipedia.org/wiki/Pseudofossil

    Pyrite disks or spindles are sometimes mistaken for fossils of sand dollars or other forms (see marcasite). Cracks, bumps, gas bubbles, and such can be difficult to distinguish from true fossils. Specimens that cannot be attributed with certainty to either fossils or pseudofossils are treated as dubiofossils. Debates on whether specific forms ...

  3. Reservoir simulation - Wikipedia

    en.wikipedia.org/wiki/Reservoir_simulation

    Reservoir simulation is an area of reservoir engineering in which computer models are used to predict the flow of fluids (typically, oil, water, and gas) through porous media. The creation of models of oil fields and the implementation of calculations of field development on their basis is one of the main areas of activity of engineers and oil ...

  4. Fossil fuel - Wikipedia

    en.wikipedia.org/wiki/Fossil_fuel

    Fossil fuel wells can contribute to methane release via fugitive gas emissions. Oil refineries also have negative environmental impacts, including air and water pollution. Coal is sometimes transported by diesel-powered locomotives, while crude oil is typically transported by tanker ships, requiring the combustion of additional fossil fuels.

  5. Petroleum geology - Wikipedia

    en.wikipedia.org/wiki/Petroleum_geology

    This is when most of the hydrocarbons are generated. Approximately 50%-90% petroleum is made and expelled at this point. The next step is the hydrocarbons entering the oil window. The oil window has to do with the source rock being the appropriate maturity, and also being at the right depth for oil exploration.

  6. Storage tank - Wikipedia

    View of Fawley Refinery large atmospheric tanks. Tanks for crude oil and oil-based fuels are chosen according to the flash point of the material. If the material is not a liquefied gas, such as LPG, tanks are atmospheric and generally come in two types: Fixed roof tanks are used for liquids with very high flash points (e.g., fuel oil, bitumen ...

  7. Storage water heater - Wikipedia

    en.wikipedia.org/wiki/Storage_water_heater

    Solar heat is clean and renewable. This is the most modern system. Increasingly, solar powered water heaters are being used. Their solar thermal collectors are installed outside dwellings, typically on the roof or walls or nearby, and the potable hot water storage tank is typically a pre-existing or new conventional water heater, or a water heater specifically designed for solar thermal.

  8. Fuel oil - Wikipedia

    en.wikipedia.org/wiki/Fuel_oil

    No. 5 fuel oil is also called Navy Special Fuel Oil (NSFO) or just navy special; No. 5 or 6 are also commonly called heavy fuel oil (HFO) or furnace fuel oil (FFO); the high viscosity requires heating, usually by a recirculated low pressure steam system, before the oil can be pumped from a bunker tank. Bunkers are rarely labeled this way in ...

  9. Produced water - Wikipedia

    en.wikipedia.org/wiki/Produced_water

    A shale gas well being drilled by a drilling rig in Pennsylvania. Produced water is a term used in the oil industry or geothermal industry to describe water that is produced as a byproduct during the extraction of oil and natural gas, [1] or used as a medium for heat extraction.
