  1. 1. Thermo-Mechanical Behaviour of Refrigerated Caverns in Hard Rock

    Författare :Rune Glamheden; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermal deformation; rock caverns; igneous rocks; thermal properties; underground storage; low temperatures; refrigeration; thermal strain;

    Sammanfattning : For almost 4 decades, underground caverns in hard rock have been used to store liquefied petroleum gases (LPG) and refrigerated products, such as foods and chemicals. The design of such facilities has, however, been founded on relatively limited knowledge of the reaction of rock masses to cooling. LÄS MER

    Författare :Thomas Probert; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; exponential decay; modelling; fractured rock; classical mechanics; quantum mechanics; Mathematical and general theoretical physics; relativity; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; relativitet; kvantmekanik; gravitation; statistisk fysik; termodynamik; Environmental technology; pollution control; kontroll av utsläpp; Miljöteknik; conformal flow; heat as a tracer; KBS-3; stress field; temperature field; analytical solution; salt buoyancy; groundwater flow; nuclear waste repository; aquifer thermal energy storage; Fysicumarkivet A:1998:Probert;

    Sammanfattning : The underground is a vast region, which is, too a large extent, unused by man. It has a large potential as a storage facility due to its vastness and availability. This thesis, which consists of eleven papers and reports, deals with nuclear waste repositories in solid rock and with aquifer thermal energy storage systems. LÄS MER

  5. 4. 3D Time-lapse Analysis of Seismic Reflection Data to Characterize the Reservoir at the Ketzin CO2 Storage Pilot Site

    Författare :Fei Huang; Christopher Juhlin; Alireza Malehmir; Ari Tryggvason; Andy Chadwick; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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.

  7. 5. Carbon allocation in underground storage organs : studies on accumulation of starch, sugars and oil

    Författare :Helle Turesson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : By increasing knowledge of carbon allocation in underground storage organs and using the knowledge to improve such crops, the competitiveness of these types of storage organs can be strengthened. Starch is the most common storage compound in tubers and roots, but some crops accumulate compounds other than starch. LÄS MER
