• Analysis of outer-casing echoes in simulations of ultrasonic pulse-echo through-tubing logging 

      Viggen, Erlend Magnus; Johansen, Tonni Franke; Merciu, Ioan Alexandru (Journal article, 2016)
      Cased petroleum wells must be logged to determine the bonding and hydraulic isolation properties of the cement. Ultrasonic logging of single casings has been widely studied and is commercially available. However, ultrasonic ...
    • Development of an outdoor auralisation prototype with 3D sound reproduction 

      Viggen, Erlend Magnus; Vennerød, Jakob; solvang, Audun; Olsen, Herold (Journal article, 2015)
      Auralisation of outdoor sound has a strong potential for demonstrating the impact of different community noise scenarios. We describe here the development of an auralisation tool for outdoor noise such as traffic or industry. ...
    • Simulation and modeling of ultrasonic pitch-catch through-tubing logging 

      Viggen, Erlend Magnus; Johansen, Tonni Franke; Merciu, Ioan Alexandru (Journal article, 2016)
      Cased petroleum wells must be logged to determine the bonding and hydraulic isolation properties of the sealing material and to determine the structural integrity status. Although ultrasonic pitch-catch logging in single-casing ...
