Avoiding Damage of CO2 Injection Wells Caused by Temperature Variations
Torsæter, Malin; Todorovic, Jelena; Lavrov, Alexandre; Gawel, Kamila; Lund, Halvor; Roy, Pratanu; Carroll, Susan (Journal article; Peer reviewed, 2017)Well integrity is a prerequisite for safe geological storage of CO2. Both active and abandoned wells are man-made channels between the storage reservoir and the atmosphere that can become leakage paths over time. The CO2 ... -
Discrete-element model of electrophoretic deposition in systems with small Debye length: effective charge, lubrication force, characteristic scales, and early-stage transport
Lavrov, Alexandre (Journal article; Peer reviewed, 2019)Electrophoresis was recently proposed as a new method for controlling properties and structure of the interface between cement and steel elements in petroleum and construction industries (Lavrov A et al., 2018). Cement ... -
Experimental Study of the use of Particles for Tracking the Interfaces in Primary Cementing of Concentric and Eccentric Wells
Taheri, Amir; Ytrehus, Jan David; Taghipour, Ali; Lund, Bjørnar; Lavrov, Alexandre; Torsæter, Malin (SINTEF Proceedings;4, Chapter; Conference object; Peer reviewed, 2019)In this study, our recent and new approach for detailed tracking of the interface between well fluid and cement by using particles is investigated. The particles can enable us to know the precise location of the interface ... -
Numerical modeling of non-Newtonian fluid flow in fractures and porous media
Bao, Kai; Lavrov, Alexandre; Nilsen, Halvor Møll (Journal article; Peer reviewed, 2017)Non-Newtonian fluids having Bingham or power-law rheology are common in many applications within drilling and reservoir engineering. Examples of such fluids are drilling muds, foams, heavy oil, hydraulic-fracturing and ... -
Well integrity for CO2 injection from ships: Simulation of the effect of flow and material parameters on thermal stresses
Aursand, Peder; Hammer, Morten; Lavrov, Alexandre; Lund, Halvor; Munkejord, Svend Tollak; Torsæter, Malin (Journal article; Peer reviewed, 2017)Ships have been shown to be the most cost-effective way to transport CO2 from many sources in the Nordic region to offshore storage sites. Injection from ships introduces new challenges for the integrity of CO2 injection ...
