  1. 1. Deriving Geothermal Reservoir Properties from Tomographic Models

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Samantha Kim; [2019]
    Nyckelord :Geothermal reservoir; super-critical fluids; optimization; seismic tomography; effective medium model; Iceland; Geotermisk energi; seismisk; mediummodel; reservoir; spricktäthet; superkritisk vätska optimisering;

    Sammanfattning : The effectiveness of the heat transfer in a geothermal reservoir strongly depends on its temperature, pressure and rock type. A porous and fractured rock is essential to provide a hot fluid circulation to a geothermal power plant. LÄS MER

  3. 2. Earthquake Analysis Using a Migration Based Detection Algorithm Applied to Local Earthquake Data

    Kandidat-uppsats, Uppsala universitet/Geofysik

    Författare :Stefan Johansson; [2017]
    Nyckelord :migration; stacking; earthquake detection; migration; stacking; detektering av jordskalv;

    Sammanfattning : In this study earthquake data is analyzed using a newly developed Migration Based Detection (MBD) algorithm (Wagner et al. 2017). LÄS MER

  4. 3. Shear-Wave Splitting Observed in Local Earthquake Data on the Reykjanes Peninsula, SW Iceland

    Master-uppsats, Geofysik

    Författare :Darina Buhcheva; [2014]
    Nyckelord :shear-wave splitting; local earthquakes; Iceland;

    Sammanfattning : Shear-wave splitting is a phenomenon observed in almost all in situ rocks. Due to propagation through stress-aligned and fluid-saturated microcracks and fractures the initial shear wave splits into two almost orthogonal waves which propagate with different velocities along similar ray paths.

  5. 4. Vulkaners betydelse för utvinning av geotermisk energi, Krafla och Hengill, Island

    Kandidat-uppsats, Institutionen för geovetenskaper

    Författare :Sofia Bergström; Sophia Sjödin; [2013]
    Nyckelord :Geotermisk energi; Island; Krafla; Hengill;

    Sammanfattning : Island har perfekta förutsättningar för att utvinna geotermisk energi. Det är beläget på den mittatlantiskaryggen mellan två aktiva plattor som interagerar med den hotspot som ligger under Island. LÄS MER

  7. 5. Remote Sensing and Statistical Analysis of Fracture Populations Around Lake Thingvallavatn, SW Iceland

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Johan Oxenstierna; [2012]
    Nyckelord :;

    Sammanfattning : This study aims at a description and statistical analysis of tectonic and magmatic fractures in the Western Volcanic Zone (WVZ) on Iceland. Two fracture populations are studied with respect to their distance to the Hengill volcano: The southern area is between 0-10 kilometers from the volcano and the northern area is between 16-25 kilometers from the volcano.
