  1. 1. Coal and Oil: The Dark Monarchs of Global Energy : Understanding Supply and Extraction Patterns and their Importance for Future Production

    Författare :Mikael Höök; Kjell Aleklett; David Rutledge; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; oil production; coal production; depletion rate; forecasting; energy supply; Physics; Fysik; Other earth sciences; Övrig geovetenskap; Physical planning; Fysisk planläggning; Other engineering physics; Övrig teknisk fysik; Physics with specialization in Global Energy Resources; Fysik med inriktning mot globala energiresurser;

    Sammanfattning : The formation of modern society has been dominated by coal and oil, and together these two fossil fuels account for nearly two thirds of all primary energy used by mankind.  This makes future production a key question for future social development and this thesis attempts to answer whether it is possible to rely on an assumption of ever increasing production of coal and oil.

  3. 2. Depletion and decline curve analysis in crude oil production

    Författare :Mikael Höök; Kjell Aleklett; Roger Bentley; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; depletion rate; decline curve analysis; crude oil production; Other earth sciences; Övrig geovetenskap; Mathematical physics; Matematisk fysik; Other engineering physics; Övrig teknisk fysik; Physics with specialization in Global Energy Resources; Fysik med inriktning mot globala energiresurser;

    Sammanfattning : Oil is the black blood that runs through the veins of the modern global energy system. While being the dominant source of energy, oil has also brought wealth and power to the western world. Future supply for oil is unsure or even expected to decrease due to limitations imposed by peak oil. Energy is fundamental to all parts of society. LÄS MER

  4. 3. Origin of organic compounds in fluids from ultramafic-hosted hydrothermal vents of the Mid-Atlantic Ridge

    Författare :Cécile Konn; Nils Holm; Jean-Luc Charlou; Barbara Sherwood Lollar; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Serpentinisation; hydrocarbons; organic compounds; ultramafic; hydrothermal; geochemistry; origin of life; Other earth sciences; Övrig geovetenskap; Other chemistry; Övrig kemi; Exogenous geochemistry; Exogen geokemi; geokemi; Geochemistry;

    Sammanfattning : Natural gas, primarily methane (CH4), is produced in substantial amounts in ultramafic-hosted hydrothermal systems. These systems could also generate oil (heavier hydrocarbons) and the first building blocks of life (prebiotic molecules). In the presence of iron bearing minerals, serpentinisation reactions generate H2. LÄS MER

  5. 4. Late Quaternary Biostratigraphy and Paleoceanography of the central Arctic Ocean

    Författare :Daniela Hanslik; Martin Jakobsson; Marit-Solveig Seidenkrantz; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Arctic Ocean; Quaternary; biostratigraphy; foraminifera; paleoceanography; Other earth sciences; Övrig geovetenskap; Marine Geoscience; marin geovetenskap;

    Sammanfattning : The central Arctic Ocean is one of the least explored deep sea regions and long biostratigraphic sediment records are sparse. The main focus of this thesis is the Arctic Ocean foraminiferal record and its application to reconstruct paleoceanographic variations and summer sea ice cover changes between late Quaternary interglacial periods.

  7. 5. Mapping bathymetry : From measurement to applications

    Författare :Benjamin Hell; Martin Jakobsson; Michele Rebesco; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ocean and coastal mapping; Digital Bathymetric Model; Geographical Information System; Applications of bathymetric data; Baltic Sea; Arctic Ocean; Seafloor morphology; Ocean circulation; Other earth sciences; Övrig geovetenskap; Marine Geoscience; marin geovetenskap;

    Sammanfattning : Surface elevation is likely the most fundamental property of our planet. In contrast to land topography, bathymetry, its underwater equivalent, remains uncertain in many parts of the World ocean. Bathymetry is relevant for a wide range of research topics and for a variety of societal needs. LÄS MER
