    Application of the POCS inversion method to cross‐borehole imaging 
    Bjarnason, Ingi Þorleifur; Menke, William (Society of Exploration Geophysicists, 1993-07)
    Cross-borehole tomography suffers from a well-known problem of data incompleteness: the limited ray coverage dictated by the poor experimental geometry implies that certain features of the velocity field are not determined by the data. Construction of ...

    Design of the subsurface observatory at Surtsey volcano, Iceland 
    Türke, Andreas; Jackson, Marie D.; Bach, Wolfgang; Kahl, Wolf-Achim; Grzybowski, Brian; Marshall, Beau; Gudmundsson, Magnus Tumi; Jørgensen, Steffen Leth (Copernicus GmbH, 2019-06-12)
    Surtsey, the youngest of the islands of Vestmannaeyjar, is an oceanic volcano created by explosive basaltic eruptions during 1963-1967 off the southern coast of Iceland. The subsurface deposits of the volcano were first sampled by a cored borehole in ...

    Nonlinear Finite-Element Analysis of Casings in High-Temperature Geothermal Wells 
    Skúlason Kaldal, Gunnar (University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Engineering, Mechanical Engineering and Computer Science, 2019-05-20)
    High-temperature geothermal wells are drilled in stages and constructed of several concentric steel casings that are cemented over their entire external surface for sealing and structural support purposes. The structural integrity of such casings is ...
