  • An aggregated template methodology: Novel automatic phase-onset identification by template matching 
    Duboeuf, Laure; Oye, Volker; Dando, Benjamin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The precision of P- and S-wave phase picking strongly determines the precision of earthquake locations, but such picking can be challenging in the case of emergent signals, large data sets or temporally varying seismic ...
  • Array Signal Processing on Distributed Acoustic Sensing Data: Directivity Effects in Slowness Space 
    Näsholm, Sven Peter; Iranpour, Kamran; Wuestefeld, Andreas; Dando, Benjamin; Baird, Alan F.; Oye, Volker (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Distributed Acoustic Sensing (DAS) involves the transmission of laser pulses along a fiber-optic cable. These pulses are backscattered at fiber inhomogeneities and again detected by the same interrogator unit that emits ...
  • Induced-seismicity geomechanics for controlled CO2 storage in the North Sea (IGCCS) 
    Park, Joonsang; Griffiths, Luke; Dautriat, Jérémie; Grande, Lars; Vera Rodriguez, Ismael; Iranpour, Kamran; Bjørnarå, Tore Ingvald; Marin-Moreno, Héctor; Mondol, Nazmul Haque; Sauvin, Guillaume; Sarout, Joel; Soldal, Magnus; Oye, Volker; Dewhurst, David N.; Choi, Jung Chan; Best, Angus Ian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    The aim of the current study, IGCCS (2017–2020), is to evaluate the feasibility of micro-seismic (MS) monitoring of CO2 injection into representative storage candidates in the North Sea, based on broad and quantitative ...
  • Inferring microseismic source mechanisms and in situ stresses during triaxial deformation of a North-Sea-analogue sandstone 
    Griffiths, Luke; Dautriat, Jérémie; Rodriguez, Ismael A Vera; Iranpour, Kamran; Sauvin, Guillaume; Park, Joonsang; Sarout, Joel; Soldal, Magnus; Grande, Lars; Oye, Volker; Dewhurst, David; Mondol, MD Nazmul Haque; Choi, Jung Chan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Monitoring microseismic activity provides a window through which to observe reservoir deformation during hydrocarbon and geothermal energy production, or CO2 injection and storage. Specifically, microseismic monitoring may ...
  • Vs30 and depth to bedrock estimates from integrating HVSR measurements and geology-slope approach in the Oslo area, Norway 
    Ghione, Federica; Köhler, Andreas; Dichiarante, Anna Maria; Aarnes, Ingrid; Oye, Volker (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    This work shows an alternative and efficient method to estimate Vs30 values and depth to basement data. The Vs30 value is the most important attribute to characterize the soil type and subsequently account for soil type ...
