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 ... -
Experimental and Numerical Study of Density-Driven Natural Convection Mechanism During Storage of CO2 in Brine Aquifers
Taheri, Amir (Doctoral thesis at NTNU;2015:170, Doctoral thesis, 2015)Storage of CO2 into geological formations is a reasonable technical choice for decreasing carbon dioxide emissions to the atmosphere. Brine aquifers are considered as one of the most favorable options for this purpose ... -
Experimental study of the use of tracing particles for interface tracking in primary cementing in an eccentric hele–shaw cell
Taheri, Amir; Ytrehus, Jan David; Lund, Bjørnar; Torsæter, Malin (Peer reviewed; Journal article, 2021)We present the results of the displacement flows of different Newtonian and Herschel–Bulkley non-Newtonian fluids in a new-developed eccentric Hele–Shaw cell with dynamic similarly to real field wellbore annulus during ... -
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, ... -
Use of concentric hele-shaw cell for the study of displacement flow and interface tracking in primary cementing
Taheri, Amir; Ytrehus, Jan David; Lund, Bjørnar; Torsæter, Malin (Peer reviewed; Journal article, 2021)We present our new designed concentric Hele-Shaw cell geometry with dynamic similarity to a real field wellbore annulus during primary cementing, and then, the results of displacement flow of Newtonian and yield-stress ... -
Use of Tracer Particles for Tracking Fluid Interfaces in Primary Cementing
Taheri, Amir; Ytrehus, Jan David; Taghipour, Ali; Lund, Bjørnar; Lavrov, Alexandre; Torsæter, Malin (Chapter, 2019)In this study, a new approach for detailed tracking of the interface between well fluid and cement by using particles is investigated. This can improve the quality of annular cementing of CO2 wells and thus the storage ...
