    • Static and Dynamic Characterization of a Deep Overburden Shale 

      Bakk, Audun; Stenebråten, Jørn; Lozovyi, Serhii; Bauer, Andreas; Sønstebø, Eyvind Frode; Fjær, Erling; Bhuiyan, Mohammad Hossain; Chakraborty, Samarjit; Holt, Rune Martin (Chapter, 2018)
      Since shales are the far most abundant overburden formation, understanding the geomechanical and rock physics behavior of shales is essential. We discuss a particular deep overburden shale in light of a thorough static and ...

    • Stress-Induced Fracturing of Reservoir Rocks: Acoustic monitoring and uCT Image Analysis 

      Pradhan, Srutarshi; Stroisz, Anna Magdalena; Fjær, Erling; Stenebråten, Jørn; Lund, Hans Karl; Sønstebø, Eyvind Frode (Journal article, 2015)
      Stress-induced fracturing in reservoir rocks is an important issue for the petroleum industry. While productivity can be enhanced by a controlled fracturing operation, it can trigger borehole instability problems by ...

    • Thermally Induced Compaction of Shales 

      Bauer, Andreas; Holt, Rune Martin; Stenebråten, Jørn; Sønstebø, Eyvind Frode; Marøen, Leni Larsen (Chapter, 2014)
      Thermally-induced, non-reversible compaction with volumetric strains of up to more than 1% has been observed in laboratory compaction tests with core plugs of several different shales. While thermallyinduced compaction is ...
