Equilibrium commodity prices with irreversible investment and non-linear technologies

Pierre Collin Dufresne

We model oil price dynamics in a general equilibrium production economy with two goods: a consumption good and oil. Production of the consumption good requires drawing from oil reserves at a fixed rate. Investment necessary to replenish oil reserves is cos ...

Hydration mediated interfacial transitions on mixed hydrophobic/hydrophilic nanodroplet interfaces

Sylvie Roke, Rüdiger Scheu, Nikolay Smolentsev, Filip Kovacik, Halil Ibrahim Okur

Interfacial phase transitions are of fundamental importance for climate, industry, and biological processes. In this work, we observe a hydration mediated surface transition in supercooled oil nanodroplets in aqueous solutions using second harmonic and sum ...

Accounting for near-wellbore fracture behavior to unlock the potential of unconventional gas wells

Brice Tanguy Alphonse Lecampion

Despite ongoing engineering efforts, unconventional horizontal gas wells completed with the multi-stage hydraulic fracturing technique are not yet producing to their full potential, as a meaningful proportion of clusters are producing marginally - if at al ...

The impact of the volumetric swelling behavior on the water uptake of gas shale

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Water uptake of gas shales is commonly considered one of the most important factors responsible for fluid loss during flowback operations after hydraulic fracturing. Imbibition experiments cover a key role in this context to analyze the impact of several f ...

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

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

Nonlinear elastic response of partially saturated gas shales in uniaxial compression

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Elastic properties of gas shales are fundamental for the geomechanical characterization of unconventional reservoirs. Due to the presence of microcracks, a non-linear elastic behaviour with hysteresis is usually exhibited when gas shales are subjected to u ...

Reversible Segregation of Ni in LaFe0.8Ni0.2O3 +/-delta During Coke Removal

Oliver Kröcher, Davide Ferri, Patrick Simon Steiger

The deactivation of supported nickel catalysts by coking is an important technological subject for many chemical processes, especially when high concentrations of unsaturated hydrocarbons are present in the feed gas. Here, the reversible segregation of Ni ...
