CO2 sequestration in deep geological formations is considered as a promising technology to reduce the impact of CO2 on the greenhouse effect. Practically, large-volume of CO2 could be injected into a system that consists of a highly porous host reservoir c ...
CO2 storage in geological formation, especially in deep aquifers, is considered as a compromising technology to reduce the impact of CO2 on the greenhouse effect. Practically, large-volume of CO2 could be injected at a high rate into a system which consist ...
Geologic carbon storage is considered to be one of the main solutions to significantly reduce CO2 emissions to the atmosphere to mitigate climate change. CO2 injection in deep geological formations entails a two-phase flow, being CO2 the non-wetting phase. ...
Emulsions of two immiscible liquids can slowly coalesce over time when stabilized by surfactant molecules. Pickering emulsions stabilized by colloidal particles can be much more stable. Here, we fabricate biocompatible amphiphilic dimer particles using a h ...
Microbial enhanced oil recovery (MEOR) depends on the in situ microbial activity to release trapped oil in reservoirs. In practice, undesired consumption is a universal phenomenon but cannot be observed effectively in small-scale physical simulations due t ...
Oil and gas production from unconventional reservoirs (i.e. tight) now accounts for about half of the total US hydrocarbon production from essentially zero ten years ago. Such a drastic increase in production from unconventional resources was made possible ...
Important properties of a crude oil, such as viscosity, are determined by the crude oil's chemical constituents. In particular, viscosity is highly dependent on the asphaltene content. Various processes that act on reservoir crude oils can alter chemical c ...
The constant flow stress reached during uniaxial deformation of electrodeposited nanocrystalline Ni reflects a quasi-stationary balance between dislocation slip and grain boundary (GB) accommodation mechanisms. Stress reduction tests allow to suppress disl ...
Thermo-mechanical effects are important in geologic carbon storage because CO2 will generally reach the storage formation colder than the rock, inducing thermal stresses. Capillary functions, i.e., retention and relative permeability curves, control the CO ...
The offshore extraction of oil and gas is an energy-intensive process associated with large CO2 and CH4 emissions to the atmosphere and chemicals to the sea. The taxation of these emissions has encouraged the development of more energy-efficient and enviro ...
