Methane gas hydrates, crystalline inclusion compounds formed from methane and water, are found in marine continental margin permafrost sediments worldwide. This article reviews the current understanding of phenomena involved hydrate formation physical properties hydrate‐bearing sediments. Formation include pore‐scale habit, solubility, spatial variability, host sediment aggregate properties. Physical thermal properties, permeability, electrical conductivity permittivity, small‐strain elastic...
The interfacial interaction between mineral surfaces and immiscible fluids determines the efficiency of enhanced oil or gas recovery operations as well our ability to inject store CO 2 in geological formations. Previous studies have shown that tension contact angle ‐water‐mineral systems change noticeably with fluid pressure. We compile previous results extend scope available data include saline water, different substrates (quartz, calcite, oil‐wet quartz, polytetrafluoroethylene (PTFE)), a...
Small pores in high specific surface clay-rich caprocks give rise to capillary entry pressures and viscous drag that hinder the migration of buoyant carbon dioxide CO2. We measured breakthrough pressure ensuing CO2 permeability through sediment plugs prepared with sand, silt, kaolinite smectite, monitored their volumetric deformation using high-pressure oedometer cells. The data show water expulsion contraction prior breakthrough, followed by preferential flow thereafter. Our experimental...
The injection of carbon dioxide, CO 2 , into methane hydrate‐bearing sediments causes the release methane, CH 4 and formation dioxide hydrate, even if global pressure‐temperature conditions remain within hydrate stability field. This phenomenon, known as ‐CO exchange or replacement, creates a unique opportunity to recover an energy resource, while entrapping greenhouse gas, dioxide. Multiple coexisting processes are involved during including heat liberation, mass transport, volume change,...
Abstract This work uses X‐ray computed micro‐tomography (μCT) to monitor xenon hydrate growth in a sandpack under the excess gas condition. The μCT images give pore‐scale distribution and pore habit space time. We use lattice Boltzmann method calculate relative permeability (k rg ) as function of saturation (S hyd structure experimental hydrate‐bearing sand retrieved from data. results suggest k ‐ S data fit well new model = (1‐S )·exp(–4.95·S rather than simple Corey model. In addition, we...
Understanding the adsorption‐induced swelling in coal is critical for predictable and enhanced bed methane production. The matrix a natural anisotropic disordered microporous solid. We develop an elastic transverse isotropic poromechanical model solids which couples adsorption strain through stress functions expresses isotherm as multivariate function depending on fluid pressure solid strains. Experimental data from literature help invert adsorptive‐mechanical properties of Brzeszcze samples...
