  2. Abiogenic petroleum origin - Wikipedia

    en.wikipedia.org/wiki/Abiogenic_petroleum_origin

    The Gravberg-1 well only produced 84 barrels (13.4 m 3) of oil, which later was shown to derive from organic additives, lubricants and mud used in the drilling process. [ 32 ] [ 33 ] [ 34 ] Kudryavtsev's Rule has been explained for oil and gas (not coal)—gas deposits which are below oil deposits can be created from that oil or its source rocks.

    Quizlet is a multi-national American company that provides tools for studying and learning. [1] Quizlet was founded in October 2005 by Andrew Sutherland, who at the time was a 15-year old student, [ 2 ] and released to the public in January 2007. [ 3 ]

  4. Petroleum - Wikipedia

    en.wikipedia.org/wiki/Petroleum

    Petroleum [a] is a naturally occurring yellowish-black liquid mixture. It consists mainly of hydrocarbons, [1] and is found in geological formations.The term petroleum refers both to naturally occurring unprocessed crude oil, as well as to petroleum products that consist of refined crude oil.

  5. Extraction of petroleum - Wikipedia

    en.wikipedia.org/wiki/Extraction_of_petroleum

    The oil well is created by drilling a long hole into the earth with an oil rig. A steel pipe (casing) is placed in the hole, to provide structural integrity to the newly drilled well bore. Holes are then made in the base of the well to enable oil to pass into the bore.

  6. Earth's energy budget - Wikipedia

    en.wikipedia.org/wiki/Earth's_energy_budget

    In this expression σ is the Stefan–Boltzmann constant and ε represents the emissivity of the atmosphere, which is less than 1 because the atmosphere does not emit within the wavelength range known as the atmospheric window. Aerosols, clouds, water vapor, and trace greenhouse gases contribute to an effective value of about ε = 0.78.

  7. Oil - Wikipedia

    en.wikipedia.org/wiki/Oil

    Crude oil originates from ancient fossilized organic materials, such as zooplankton and algae, which geochemical processes convert into oil. [8] The name "mineral oil" is a misnomer, in that minerals are not the source of the oil—ancient plants and animals are. Mineral oil is organic.

    The atmosphere returns to a CO 2 and N 2 dominated atmosphere after H 2 escapes from Earth to space. From: Nicholas F. Wogan et al 2023 Planet. Sci. J. 4 169. Licensed under CC-BY 4.0. A large factor controlling the redox budget of early Earth's atmosphere is the rate of atmospheric escape of H 2 after Earth's formation.

  9. Hubbert peak theory - Wikipedia

    en.wikipedia.org/wiki/Hubbert_peak_theory

    "Hubbert's peak" can refer to the peaking of production in a particular area, which has now been observed for many fields and regions. Hubbert's peak was thought to have been achieved in the United States contiguous 48 states (that is, excluding Alaska and Hawaii) in the early 1970s. Oil production peaked at 10.2 million barrels (1.62 × 10 ^ 6 m 3) per day in 1970 and then dec
