  1. 1. Geologisk karaktärisering av den kambriska Faluddensandstenen i Östersjön och dess lämplighet för koldioxidlagring

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Kaisa Bengtsson; [2023]
    Nyckelord :Koldioxidlagring; djupt liggande akvifer; Faludden; St. Sutarve-2018; CO2-storage; deep saline aquifers; Earth and Environmental Sciences;

    Sammanfattning : The Geological Survey of Sweden (SGU) has spent several years investigating the Swedish bedrock to find suitable bedrock for geological storage of carbon dioxide. Deep saline aquifers are considered to have the greatest potential, and the Cambrian Faludden Sandstone subcropping in the Baltic Sea east of Gotland, shows great potential as a storage aquifer.

  3. 2. Petrological characterization of the Cambrian sandstone reservoirs in the Baltic Basin, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Tawonga Chitindingu; [2018]
    Nyckelord :Cambrian; Baltic Basin; porosity; permeability; quartz; cement; Earth and Environmental Sciences;

    Sammanfattning : The Cambrian sandstone reservoirs of the Baltic Basin have been identified by the Geological Survey of Sweden (SGU) as potential CO2 storage sites in line with regulations regarding Carbon Capture and Storage (CCS). In order to understand the petrological and petrophysical characteristics of the sandstone units, 54 thin sections from the three main Cambrian sandstone units were studied. LÄS MER

  4. 3. En provenansstudie av Kågerödsformationen i NV Skåne : tungmineral och petrografi

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Karin Rasmussen; [2006]
    Nyckelord :Keuper; Kågerödsformationen; arkos; tungmineral; granat; Kågeröd Formation; arkoses; heavy mineral; garnet; Earth and Environmental Sciences;

    Sammanfattning : Keupersedimenten i NV Skåne utgörs huvudsakligen av röda, gröna och grå arkosiska sandstenar tillhörande Kågerödsformationen. Sedimenten avsattes i en kontinental arid miljö med episodisk nederbörd som resulterade i flodbildning och därmed transport nedför ett dåtida höjdområde. LÄS MER

  5. 4. Correlation between diagenesis and sedimentary facies of the Bentheim Sandstone, the Schoonebeek field, The Netherlands

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Pär Malmborg; [2002]
    Nyckelord :Bentheim Sandstone; sedimentary facies; diagenesis; petroleum reservoir; Lower Cretaceous; Valanginian; Lower Saxony Basin; Schoonebeek; Gildehaus; Earth and Environmental Sciences;

    Sammanfattning : The Valanginian (Lower Cretaceous) Bentheim succession of the Schoonebeek field is deposited in a shallow-marine environment along the southern and southwestern coast of the Lower Saxony Basin in eastern Netherlands. Three cores from Schoonebeek field, selected by NAM (Nederlandse Aardolie Maatschappij), and a number of samples from an outcrop in the Bentheim Sandstone at Gildehaus were studied. LÄS MER

  7. 5. Permeability variation in a tidal Jurassic deposit, Höganäs basin, Fennoscandian Border Zone

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Henrik Jonsson; [2002]
    Nyckelord :permeability; Höganäs Formation; anisotropy; heteroliths; Lower Jurassic; quartz cement; Earth and Environmental Sciences;

    Sammanfattning : An examination of permeability differences was made on plugs obtained from six drill cores in both horizontal and vertical directions, representing different facies of the Hettangian strata from the Höganäs Formation. The permeability analyses distinguish permeability differences from anisotropy and an index was created to evaluate the anisotropy. LÄS MER
