An Analytical Solution for Pressure-Induced Deformation of Anisotropic Multilayered Subsurface
Park, Joonsang; Bjørnarå, Tore Ingvald; Bohloli, Bahman (Peer reviewed; Journal article, 2021) -
Capturing the coupled hydro-mechanical processes occurring during CO2 injection – example from In Salah
Bjørnarå, Tore Ingvald; Mathias, Simon A.; Nordbotten, Jan Martin; Park, Joonsang; Bohloli, Bahman (Journal article, 2014)At In Salah, CO2 is removed from the production stream of several natural gas fields and re-injected into a deep and relatively thin saline formation, in three different locations. The observed deformation on the surface ... -

Effect of brine-CO2 fracture flow on velocity and electrical resistivity of naturally fractured tight sandstones
Nooraiepour, Mohammad; Bohloli, Bahman; Park, Joonsang; Sauvin, Guillaume; Skurtveit, Elin; Mondol, Nazmul Haque (Peer reviewed; Journal article, 2017)Fracture networks inside geological CO2 storage reservoirs can serve as primary fluid flow conduit, particularly in low-permeability formations. While some experiments focused on the geophysical properties of brine- and ... -
Evaluation of reservoir and cap-rock integrity for the Longyearbyen CO2 storage pilot based on laboratory experiments and injection tests
Bohloli, Bahman; Skurtveit, Elin; Grande, Lars; Titlestad, Geir Ove; Børresen, Marion; Johnsen, Øistein; Braathen, Alvar (Journal article, 2014)Mechanical laboratory testing and interpretation of injection tests of the Longyearbyen CO2 storage pilot are used to evaluate geomechanical conditions for safe CO2 storage. The laboratory testing program includes compressive ... -
Experimental and analytical assessment of Draupne shale seal integrity for CO2 storage sites
Soldal, Magnus; Skurtveit, Elin; Bohloli, Bahman; Wilkinson, Heidi; Choi, Jung Chan; Griffiths, Luke; Smith, Halvard (Lecture, 2019)Carbon dioxide (CO2) capture and storage is one of the most important measures to reduce the atmospheric concentration of CO2. To ensure safe storage, operations must be conducted in way that respects operational limitations. ... -
Frictional Properties and Seismogenic Potential of Caprock Shales
Bohloli, Bahman; Soldal, Magnus; Smith, Halvard; Skurtveit, Elin; Choi, Jung Chan; Sauvin, Guillaume (Peer reviewed; Journal article, 2020)Fractures and faults are critical elements affecting the geomechanical integrity of CO2 storage sites. In particular, the slip of fractures and faults may affect reservoir integrity and increase potential for breach, may ... -
