VA texte à recopier ici / bas de page prêt en VA: La Microfluidique pour comprendre et résoudre le colmatage géologique

L’injectivité dans les formations géologiques est un enjeu connu qui affecte des domaines d’activités liés aux énergies nouvelles et au climat (géothermie, stockage souterrain de CO2, etc.). Le colmatage des formations géologiques, problème récurrent qui engendre des pertes d’injectivité, est lié au fait que les eaux réinjectées sont fréquemment chargées en éléments organiques et minéraux en suspension, sous forme de particules colloïdales. Pour tenter d’y remédier, ou tout au moins de le minimiser, il est important de bien comprendre les mécanismes à l’œuvre. C’est ce à quoi s’est attaché ce travail de thèse, via une approche microfluidique (Figure 1) combinant deux techniques de visualisation : l'imagerie optique [1] et l'imagerie par fluorescence induite par laser [2]...

SC3 - Microfluidics supporting preserved injectivity

Injectivity in geological formations has long been an important factor in oil production (enhanced recovery) but it is now just as important in fields related to new energies and the climate (geothermal energy, CO2 storage, etc.). Injectivity losses, which result from the clogging of geological formations, are a recurrent problem associated with the fact that reinjected water often carries a high concentration of organic and mineral elements in suspension, in the form of colloidal particles...

Ageing of technical fluids in multifunctional environments

By combining battery, electric machine, power electronics and mechanical transmission, the electric vehicle is an example of an application that combines a range of constraints for the formulation of technical fluids. In recent years, there has been renewed interest in the study of the latter for the transport sector...

Microfluidics and Chemoinformatics: a highly complementary approach to studying material/fluid compatibility

Pour de nombreuses applications industrielles, comme le recyclage chimique des plastiques, ou encore pour assurer la compatibilité entre polymères et nouveaux carburants, il est essentiel d’anticiper les interactions entre matériaux et fluides...

Processes are converting to microfluidics

The diversification of resources (atypical oil feeds or bio-based feeds) is leading to the development of new conversion processes a or to the upgrading of flexibility for existing ones. These
