Effect of convective mixing process on storage of CO2 in saline aquifers with layered permeability.
Taheri, Amir; Torsæter, Ole; Lindeberg, Erik Gøsta Brun; Hadia, Nanji; Wessel-Berg, Dag (Journal article, 2021)Convective mixing of free-phase CO2 and brine in saline aquifers is an established technique to accelerate the CO2 dissolution process. Correct estimation of the convection onset time and rate of CO2 dissolution into brine ... -
Large Scale Tertiary CO2 EOR in Mature Water Flooded Norwegian Oil Fields
Lindeberg, Erik Gøsta Brun; Grimstad, Alv-Arne; Bergmo, Per Eirik Strand; Wessel-Berg, Dag; Torsæter, Malin; Holt, Torleif (Journal article; Peer reviewed, 2017)A technical-economical model for a large-scale infrastructure combining CO2 EOR and aquifer storage has been used to construct a scenario including 23 Norwegian Continental Shelf oil fields that have been identified as ... -
Polymer Gels Made with Functionalized Organo-Silica Nanomaterials for Conformance Control
Najafiazar, Bahador; Wessel-Berg, Dag; Bergmo, Per Eirik Strand; Simon, Christian; Yang, Juan; Torsæter, Ole; Holt, Torleif (Journal article; Peer reviewed, 2019)Deep placement of gel in waterflooded hydrocarbon reservoirs may block channels with high water flow and may divert the water into other parts of the reservoir, resulting in higher oil production. In order to get the gel ... -
Qualitative and quantitative experimental study of convective mixing process during storage of CO2 in heterogeneous saline aquifers
Taheri, Amir; Torsæter, Ole; Lindeberg, Erik Gøsta Brun; Hadia, Nanji; Wessel-Berg, Dag (Journal article; Peer reviewed, 2018)CO2 dissolution is considered as one of the most promising mechanisms for trapping of free-phase CO2 into brine. It causes an increased density of the brine and initiation of gravitational instability that eventually leads ... -
Simulation study of density-driven natural convection mechanism in isotropic and anisotropic brine aquifers using a black oil reservoir simulator
Taheri, Amir; Wessel-Berg, Dag; Torsæter, Ole (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, ...
