Waterless fracturing technologies for unconventional reservoirs-opportunities for liquid nitrogen

TL;DR: In this paper, the capacity and applicability of cryogenic fracturing using liquid nitrogen are demonstrated and examined, and the efficacy of liquid nitrogen in enhancing fracture initiation and propagation in concrete samples, and shale and sandstone reservoir rocks.

Hydrogen wettability of quartz substrates exposed to organic acids; Implications for hydrogen geo-storage in sandstone reservoirs

TL;DR: In this paper, the authors determined the wettability of sandstone rock representative substrate through an extensive set of experiments in the presence of hydrogen and showed that pure quartz was inherently strongly water-wet (where θa is 40.8° and θr is 35.1°).
Journal ArticleDOI

Influence of pressure, temperature and organic surface concentration on hydrogen wettability of caprock; implications for hydrogen geo-storage

TL;DR: In this article, the authors measured advancing and receding contact angles of mica substrates at various representative thermo-physical conditions (pressures 0.1-25 MPa, temperatures 308-343 K, and stearic acid concentrations of 10−9 - 10−2 mol/L).
Journal ArticleDOI

Hydrogen wettability of carbonate formations: Implications for hydrogen geo-storage.

TL;DR: In this paper , the authors measured the hydrogen wettability of calcite-rich formations and concluded that the optimum conditions for de-risking H2 storage projects in carbonates are low pressures, high temperatures, low salinity, and low organic surface concentration.

Lattice BGK Models for Navier-Stokes Equation

TL;DR: In this article, the Navier-Stokes equation is obtained from the kinetic BGK equation at the second-order approximation with a properly chosen equilibrium distribution, with a relaxation parameter that influences the stability of the new scheme.

Porous Media: Fluid Transport and Pore Structure

TL;DR: In this paper, the authors examined the relationship between transport properties and pore structure of porous material and presented models of pore structures with a discussion of how such models can be used to predict the transport properties of porous media.

Scaling theory of percolation clusters

TL;DR: In this article, the scaling theory of phase transition has been used to explain percolation through the cluster properties; it can also be used as an introduction to critical phenomena at other phase transitions for readers not familiar with scaling theory.

Pore-scale imaging and modelling

TL;DR: Pore-scale imaging and modelling is becoming a routine service in the oil and gas industry as discussed by the authors, and has potential applications in contaminant transport and carbon dioxide storage, which has been shown to transform our understanding of multiphase flow processes.
