2.5D Inversion and Joint Interpretation of CSEM Data at Sleipner CO2 Storage
Park, Joonsang; Sauvin, Guillaume; Vöge, Malte (Peer reviewed; Journal article, 2017)In this paper, we revisit the marine controlled-source electromagnetic (CSEM) data, acquired above the Sleipner CO2 storage, in order to further study the dataset and conclude the feasibility of marine CSEM for offshore ... -
CO2 Flow, Alteration And Geomechanical Response In Confining Units – An Experimental ApproachGreen Open Access
Skurtveit, Elin; Sundal, Anja; Soldal, Magnus; Sauvin, Guillaume; Bjørnarå, Tore Ingvald (Lecture, 2018)Seal integrity during injection operations is a topic of great interest both within the CO2 storage community, for wastewater injection and traditional reservoir pressure support. The Little Grand Wash fault, central Utah, ... -
Combining CSEM or gravity inversion with seismic AVO inversion, with application to monitoring of large-scale CO2 injection
Tveit, Svenn; Mannseth, Trond; Park, Joonsang; Sauvin, Guillaume; Agersborg, Remy (Peer reviewed; Journal article, 2020)A sequential inversion methodology for combining geophysical data types of different resolutions is developed and applied to monitoring of large-scale CO2 injection. The methodology is a two-step approach within the Bayesian ... -
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 ... -
Experimental investigation of natural fracture stiffness and flow properties in a faulted CO2 bypass system (Utah, USA)
Skurtveit, Elin; Sundal, Anja; Bjørnarå, Tore Ingvald; Soldal, Magnus; Sauvin, Guillaume; Zuchuat, Valentin; Midtkandal, Ivar; Braathen, Alvar (Peer reviewed; Journal article, 2020)Fracture stiffness and flow properties have been measured in the laboratory using naturally fractured fault rock samples from the Little Grand Wash fault, Utah, USA. We compare fracture closure and related flow change ... -
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 ... -
Impact of data acquisition parameters and processing techniques on S-wave velocity profiles from MASW – Examples from Trondheim, Norway
Sauvin, Guillaume; Vanneste, Maarten; L'Heureux, Jean-Sébastien; O'Connor, P; O'Rourke, S.; O'Connell, Y.; Long, M. (Chapter, 2016)The shear modulus is one of the most important engineering parameters, and it relates directly to the soil's shear-wave velocity. Shear-wave velocities can be derived from both laboratory measurements (e.g., bender elements) ... -

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 (Peer reviewed; Journal article, 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 ... -
Pressure Induced Deformation and Flow Using CO2 Field Analogues, Utah
Skurtveit, Elin; Braathen, Alvar; Larsen, Eivind B.; Sauvin, Guillaume; Sundal, Anja; Zuchuat, Valentin (Peer reviewed; Journal article, 2017)Exhumed reservoirs providing evidence of CO2 accumulation and transport in geological history offer a unique possibility to supplement our knowledge on leakage processes observed along faults and fractures. A field location ...
