Constrained AVO for CO2 storage monitoring at Sleipner
(Journal article; Peer reviewed, 2017)A feasibility study of inverting for CO2 elastic properties using a model based AVO inversion is carried out. We use principal component analysis on a set of PP reflection coefficients to calculate an optimal basis function ... -
Experimental Verification of CO2 Dissolution Rate Due to Diffusion Induced Convection
(Journal article; Peer reviewed, 2017)An experimental setup has been designed for measuring the dissolution rate of buoyant CO2 into the water phase below. Experiments were performed in a high-pressure cell, where the water phase was stabilized by a porous ... -
High frequency ghost cavitation - a comparison of two seismic air-gun arrays using numerical modeling
(Journal article; Peer reviewed, 2017)Ghost cavitation is probably the mechanism behind the majority of high frequencies (above 5 kHz) generated by seismic air-gun arrays. Such high frequencies are less important in seismic reflection imaging. High frequency ... -
Shale Creep as Leakage Healing Mechanism in CO2 Sequestration
(Journal article; Peer reviewed, 2017)Experiments on shale specimens targeted creep deformation in order to investigate whether this mechanism could be relied upon to close fractures and stop leakage near injection wells. Uniaxial compression tests were conducted ... -
Simulation study of density-driven natural convection mechanism in isotropic and anisotropic brine aquifers using a black oil reservoir simulator
(Journal article; Peer reviewed, 2013)For simulation models of density-driven natural convection in brine aquifers gravitational instabilities are usually triggered by numerical round off errors. Using this method for initiating onset of convective flow, ...
