  2. 1. Application of the Seismic Reflection Method in Mineral Exploration and Crustal Imaging : Contributions to Hardrock Seismic Imaging

    Author : Omid Ahmadi; Christopher Juhlin; Alireza Malehmir; Gilles Bellefleur; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seismic reflection; Hardrock; Mineral exploration; Crustal imaging; Interpretation; Modeling; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The seismic reflection method has been used extensively in mineral exploration and for imaging crustal structures within hardrock environments. In this research the seismic reflection method has been used and studied to address problems associated with hardrock settings. READ MORE

  4. 2. Characterization of the structure, stratigraphy and CO2 storage potential of the Swedish sector of the Baltic and Hanö Bay basins using seismic reflection methods

    Author : Daniel Sopher; Christopher Juhlin; Alireza Malehmir; Christian Hübscher; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; Baltic Basin; Hanö Bay Basin; OPAB dataset; Seismic reflection; CO2 storage capacity; Seismic interpretation; Seismic processing; Vectorising; Digitizing; Tornquist Zone; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : An extensive multi-channel seismic dataset acquired between 1970 and 1990 by Oljeprospektering AB (OPAB) has recently been made available by the Geological Survey of Sweden (SGU). This thesis summarizes four papers, which utilize this largely unpublished dataset to improve our understanding of the geology and CO2 storage capacity of the Baltic and Hanö Bay basins in southern Sweden.

  5. 3. Reflection seismic investigation in the Skellefte ore district : A basis for 3D/4D geological modeling

    Author : Mahdieh Dehghannejad; Christopher Juhlin; Ari Tryggvason; Charles Hurich; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Skellefte district; reflection seismic; mineral exploration; 3D 4D modeling; mineralization; faults and shear zones; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The Skellefte ore district in northern Sweden is a Palaeoproterozoic volcanic arc and one of the most important ones hosting volcanogenic massive sulfide (VMS) deposits, producing mainly base metals and orogenic gold deposits. Due to high metal prices and increased difficulties in finding shallow deposits, the exploration for and exploitation of mineral resources is quickly being moved to greater depths. READ MORE

  6. 4. Active and passive seismic methods for investigating the glacially-triggered Burträsk fault

    Author : Ruth A. Beckel; Christopher Juhlin; Alireza Malehmir; Lars Nielsen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Burträsk fault; Glacially-triggered faulting; Crooked-line reflection seismics; Cross-dip correction; Stacking-based location; Microearthquake source observations; Passive seismic imaging; Seismic interferometry; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : Glacially-triggered faults are of high scientific interest since their formation was likely accompanied by major earthquakes and they are still a centre of seismicity in northern Fennoscandia, today. Imaging their deeper structure mainly relies on reflection seismics since the method generally has the best resolving power at depth of all geophysical methods. READ MORE

  7. 5. Quantifying the Seismic Response of Underground Structures via Seismic Full Waveform Inversion : Experiences from Case Studies and Synthetic Benchmarks

    Author : Fengjiao Zhang; Christopher Juhlin; Ari Tryggvason; Yanghua Wang; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; full waveform inversion; waveform tomography; CO2 monitoring; CO2 sequestration; time lapse seismic; Inversion; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : Seismic full waveform inversion (waveform tomography) is a method to reconstruct the underground velocity field in high resolution using seismic data. The method was first introduced during the 1980’s and became computationally feasible during the late 1990’s when the method was implemented in the frequency domain. READ MORE
