New porous microstructure descriptors based on tortuosity and accessibility

IFP Energies nouvelles has developed new morphological descriptors for porous networks. The result of work carried out in partnership by two of its research divisions, they are hinged around the concepts of accessibility and tortuosity to describe paths within a material.

Colloid transport in porous media: deposits and plugging

The transport of colloidal particles in porous media is relevant to a number of fields, including geosciences and environmental engineering. Particle-matrix interactions can lead to deposit formation and accumulation, potentially damaging the medium and altering its permeability. (...) At IFPEN, the problem was originally studied for oil and gas production, but research has now been extended to include the fields of geothermal energy and geological storage of CO2.

X-rays and Neutrons for imaging salt migration

Salt precipitation in permeable rocks is a risk faced by some energy sectors, particularly for gas storage in geological formations during operational phases (injection and extraction), when there is contact with saline aquifers. (...) This precipitation reduces the space where fluids can circulate, altering rock permeability, or even leading to plugging under certain conditions. In order to understand the underlying mechanisms behind this damaging phenomenon, experiments examining gas flow in a brine-saturated porous medium were conducted on IFPEN’s CAL-X flow test bench...

Underground modeling: an essential step for the energy transition

To address the challenges of the energy transition, the subsurface has an important role to play, both in terms of providing resources and offering storage solutions. (...) Numerical models can help gain a better understanding of the subsurface with a view to its long-term management and optimal use. Developed for a number of years now at IFPEN, initially for the petroleum industry, such models cover scales ranging from the sedimentary basin to the reservoir...

Global change, impact on landscapes and water resources

Today, the impact of climate change and human activities on the evolution of landscapes and water resources is a major challenge. Predicting it requires dedicated tools capable of evaluating, 100 years ahead, the consequences of different scenarios on watersheds and groundwater. To this end, IFPEN is developing modeling approaches targeting erosion-transport-deposition phenomena combined with surface and subsurface flows. ...

Digital Rock Physics at IFPEN

Today, characterization of geological reservoirs, a long-standing theme in petroleum exploration, becomes a base of interest for a variety of applications, such as CO2 and hydrogen storage as well as geothermal energy. In recent years, the combined use of 3D microtomography (or micro-CT ) imaging and advanced simulation techniques has allowed the emergence of a digital approach to computing the petrophysical properties of reservoir rocks (Digital Rock Physics). This represents a real complement - and in some cases an alternative - to traditional laboratory measurements.
