Fluorinated surfactants in droplet-based microfluidics: Influence of their composition on the properties of emulsion drops

Miniaturization has been a driving force in many areas of science and technology, most notably in the electronics industry. Droplet-based microfluidics, a methode to produce emulsion drops in a controlled way and at high-throughputs, enables the miniaturiz ...

Cross-talk between emulsion drops: how are hydrophilic reagents transported across oil phases?

Bart Deplancke, Esther Amstad, Antoine Claude Jean Vian, Gianluca Nicolas Etienne, Marjan Biocanin

Emulsion drops are frequently used as vessels, for example, to conduct biochemical reactions in small volumes or to perform screening assays at high throughputs while consuming minimal sample volumes. These applications typically require drops that do not ...

Microbial dynamics in petroleum oilfields and their relationship with physiological properties of petroleum oil reservoirs

Edgard Gnansounou

Petroleum is produced by thermal decay of buried organic material over millions of years. Petroleum oilfield ecosystems represent resource of reduced carbon which favours microbial growth. Therefore, it is obvious that many microorganisms have adapted to h ...

Coupled Thermo-hydro-Mechanical Effects on Caprock Stability During Carbon Dioxide Injection

Lyesse Laloui, Chao Li

This study presents a numerical investigation of the effects of coupled material properties on the caprock stability. A thermo-hydro-mechanical framework is proposed in order to reproduce the physical processes. The results indicate that for a given geomet ...

Modelling the global primary extraction, supply, price and depletion of the extractable gogical resources using the cobalt model

The global supply of cobalt was simulated by combining 3 different system dynamics models; BRONZE, PGM and STEEL. The present use of cobalt shows a low degree of recycling and systemic losses are significant. The reserves of cobalt are not very large (20-2 ...

Pore-scale analysis of the minimum liquid film thickness around elongated bubbles in confined gas-liquid flows

John Richard Thome, Alessio Ferrari, Mirco Magnini, Albert Matthias Beisel

The fluid mechanics of elongated bubbles in confined gas-liquid flows in micro-geometries is important in pore-scale flow processes for enhanced oil recovery and mobilization of colloids in unsaturated soil. The efficiency of such processes is traditionall ...

Potential for Fault Reactivation Due to CO2 Injection in a Semi-Closed Saline Aquifer

Lyesse Laloui, Victor Vilarrasa Riano, Roman Makhnenko

CO2 injection in extensive saline aquifers that present no faults is unlikely to damage the caprock sealing capacity. In contrast, CO2 injection in closed reservoirs will induce a large pressure buildup that may reactivate the low-permeable faults that bou ...

Multi-objective Optimization of Supercritical Water Gasification of Leftover Brazilian Ginseng Roots After Phytochemical Recovery Steps

François Maréchal, Adriano Viana Ensinas, Alberto Mian, Juliana Queiroz Albarelli, Diego Tresinari dos Santos

The present study aims at studying the supercritical water gasification (SCWG) of the leftover Brazilian ginseng roots after phytochemicals extraction for synthetic natural gas (SNG) production, envisioning the development of a promising Brazilian ginseng ...

Modelling of fluid injection into a frictional weakening dilatant fault

Brice Tanguy Alphonse Lecampion, Federico Ciardo

Fluid injection at a pressure below the local minimum principal total stress in a fault may (re)activate shear crack propagation (hydroshearing). Because of the presence of asperities along the fault's surfaces, the fault hydraulic width increase with the ...
