  2. 16. Scattering of seismic waves in random velocity models : Finite difference simulation

    Author : Lena Frenje; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The small-scale heterogeneities within the Earth's crust and the effect these heterogeneities have on seismic waves have gained increasing interest in the last 15 years. One approach to study seismic wave scattering is through numerical simulations in random media. READ MORE

  4. 17. Seismics, 2D and 3D Inversion of Magnetotellurics : Jigsaw pieces in understanding the Skellefte Ore District

    Author : María de los Ángeles García Juanatey; Ari Tryggavson; Ute Weckmann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetotellurics; 2D inversion; 3D inversion; hard rock seismics; mineral exploration; integrated geophysics; 4D modeling; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The Skellefte District (SD) is one of the richest metallogenic mining areas in Sweden. The main deposits consist of volcanic-hosted massive sulphides (VHMS) rich in zinc, copper, lead, gold and silver, that have been explored and mined for more than a century. READ MORE

  5. 18. Electromagnetic studies of the continental crust in Sweden

    Author : Mehran Gharibi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : Plane-wave electromagnetic methods are powerful tools for probing the earth from the surfaceto depths of a few hundred kilometers. The airborne VLF technique is widely used to map theelectrical conductivity variations of shallow geological structures. READ MORE

  6. 19. Geophysical studies of the upper crust of the central Swedish Caledonides in relation to the COSC scientific drilling project

    Author : Peter Hedin; Christopher Juhlin; Alireza Malehmir; Bjarne Almqvist; Charles Hurich; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; reflection seismic; collisional orogeny; Scandinavian Caledonides; COSC; scientific drilling; geophysical logging; gravity; magnetics; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The Collisional Orogeny in the Scandinavian Caledonides (COSC) project aims to provide a deeper understanding of mountain belt dynamics through scientific deep drilling in the central parts of the mountain belt of western Sweden. The main targets include a subduction related allochthon, the basal orogenic detachment and the underlying partially subducted Precambrian basement. READ MORE

  7. 20. 3D Time-lapse Analysis of Seismic Reflection Data to Characterize the Reservoir at the Ketzin CO2 Storage Pilot Site

    Author : Fei Huang; Christopher Juhlin; Alireza Malehmir; Ari Tryggvason; Andy Chadwick; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2 storage; 3D Time-lapse 4D ; Reservoir characterization; Seismic simulation; Spectral decomposition; Wavelet phase; Tuning frequency; Thin-layer thickness; Seismic monitoring; Seismic processing; Quantitative interpretation; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : 3D time-lapse seismics, also known as 4D seismics, have great potential for monitoring the migration of CO2 at underground storage sites. This thesis focuses on time-lapse analysis of 3D seismic reflection data acquired at the Ketzin CO2 geological storage site in order to improve understanding of the reservoir and how CO2 migrates within it.
