Formation of natural gas hydrates in marine sediments 1. Conceptual model of gas hydrate growth conditioned by host sediment properties
The stability of submarine gas hydrates is largely dictated by pressure and temperature, gas composition, and pore water salinity. However, the physical properties and surface chemistry of deepExpand

Formation of natural gas hydrates in marine sediments: 2. Thermodynamic calculations of stability conditions in porous sediments
A thermodynamic model for hydrate formation is used to compute the solubility of methane in pore water in equilibrium with gaseous methane or methane hydrate or both. Free energy of water in theExpand

Fault transmissibility in clastic-argillaceous sequences controlled by clay smear evolution
The continuity of clay smears evolving in sealed direct shear experiments of initially intact sandstone-mudrock sequences was quantified to large displacements up to more than ten times the thicknessExpand

An experimental and numerical investigation on the hydromechanical behaviour of carbonate fault zones upon reactivation: the impact of carbonate mud sealing layers and overall research outcomes
Abstract To contribute to the understanding of the impacts of fault reactivation induced by reservoir exploitation, we describe the final series of laboratory experiments, numerical simulations andExpand

Constraints on seismic reflections and mode conversions at bottom simulating reflectors associated with gas hydrates
Abstract Bottom simulating reflectors (BSRs) are the primary seismic signatures of subsurface gas hydrate accumulations. Inference about the presence of gas hydrates only from P wave data hampersExpand

Slow slip source characterized by lithological and geometric heterogeneity
Slow slip events on subduction megathrusts are linked to subduction of rough crust and heterogeneous fault rock properties. Slow slip events (SSEs) accommodate a significant proportion of tectonicExpand

Fast automatic detection of geological boundaries from multivariate log data using recurrence
TLDR
We introduce a multivariate technique, that can identify geological boundaries from petrophysical or geochemical data. Expand
