Safe Storage Parameters During CO₂ Injection Using Coupled Reservoir-Geomechanical Analysis

T.I. Bjørnarå[1], E. Aker[1], and E. Skurtveit[1]
[1]NGI, Oslo, Norway

Safe short term storage of CO2 depends mainly on structural and solubility trapping. On longer term, mineral trapping is also contributing to the trapping of CO2. To be able to investigate the importance of these different storage mechanisms, a finite element model for simulation of CO2 ... En savoir plus

Lamb Waves in Fluid-Loaded Plates

T. Kaufmann[1], F. Kassubek[1], D. Pape [1], M. Lenner[1]
[1]ABB Corporate Research, Baden-Dättwil, Switzerland

Lamb waves are elastic waves propagating in free solid plates. In the case of plates loaded with a fluid, the equations describing these waves have to be modified to include the effects of the fluid. In our work we have tackled this problem using COMSOL Multiphysics®. We have used the ... En savoir plus
