The stability of submarine gas hydrates is largely dictated by pressure and temperature, composition, pore water salinity. However, the physical properties surface chemistry deep marine sediments may also affect thermodynamic state, growth kinetics, spatial distributions, forms clathrates. Our conceptual model presumes that hydrate behaves in a way analogous to ice freezing soil. Hydrate inhibited within fine‐grained combination reduced activity vicinity hydrophilic mineral surfaces, excess...
Shale gas has become a significant resource play in the USA over past few years and companies are now evaluating shale potential of many sedimentary basins, including several onshore basins within Australia. The renewed focus on rock sequences that have hitherto largely been ignored necessitated development workflows methods for characterising shales. Along with deployment new comes need interpretation frameworks order to understand properties such as source quality, mechanical production...
Abstract Despite its widespread use in petrophysics, tortuosity remains a poorly understood concept. Tortuosity can have various meanings when used by physicists, engineers or geologists to describe different transport processes taking place porous material. Values for geometrical, electrical, diffusional and hydraulic are general from one another. Electrical is defined terms of conductivity whereas usually geometrically, typically computed temporal changes concentration. A better approach...

Natural sediments have a broad distribution sizes, effective size function fraction space filled by (phase fraction). The conditions + thus depend on fraction.

Wettability in argillaceous materials is poorly understood, yet it critical to hydrocarbon recovery clay‐rich reservoirs and capillary seal capacity both caprocks fault gouges. The hydrophobic or hydrophilic nature of clay‐bearing soils sediments also controls a large degree the movement spilled nonaqueous phase liquids subsurface options available for remediation these pollutants.

Slow slip events (SSEs) accommodate a significant proportion of tectonic plate motion at subduction zones, yet little is known about the faults that actually host them. The shallow depth (<2 km) well-documented SSEs Hikurangi zone offshore New Zealand offers unique opportunity to link geophysical imaging with direct access incoming material represents megathrust fault rocks hosting slow slip. Two recent International Ocean Discovery Program Expeditions sampled this before it entrained...
The adsorption of hydrocarbon (pure CH4 and C2H6) on illitic clay was investigated at temperatures 333, 363, 393 K (60, 90, 120 °C) over a range pressures up to 30 MPa using grand canonical Monte Carlo (GCMC) simulations. We first discussed the comparability molecular simulation results with experimental measurements. Our indicate that excess are comparable measurements if they both expressed per unit surface area available for instead mass. gas density profiles C2H6 is mainly affected by...
The adsorption of CH4 and CO2 onto illitic clay was investigated at the temperatures 298, 313, 328, 358, 423 K (25, 40, 55, 85, 150 °C) over a range pressures up to 50 MPa using grand canonical Monte Carlo (GCMC) simulations. Our simulation results showed spontaneous exothermic behavior illite for with enthalpy changes −3.50 kJ/mol −25.09 kJ/mol, respectively. indicated that interlayer counter cations (K+) play an important role in adsorption. Methane is mainly affected by surface layers...
Observations and modeling studies have shown that during CO2 injection into underground carbonate reservoirs, the dissolution of formation water forms acidic brine, leading to fluid-rock interactions can significantly impact hydraulic properties host formation. However, impacts these on pore structure macroscopic flow rock are poorly characterized both for near-wellbore region deeper reservoir. Little attention has been given influence pressure drop from reservoir body disturbing ionic...

Maximizing the recovery of known hydrocarbon reserves is one biggest challenges facing petroleum industry today. Optimal production strategies require accurate monitoring production-induced changes reservoir saturation and pressure over life field. Time-lapse seismic technology increasingly used to map these in space time. However, until now, interpretation time-lapse data has been mostly qualitative. In order allow estimation saturation, it necessary know quantitative relationship between...
Abstract Understanding the adsorption mechanisms of CO 2 and N in illite, one main components clay shale, is important to improve precision shale gas exploration development.
