Hydrogen (H2) is an attractive energy carrier to move, store, and deliver in a form that can be easily used. Field proven technology for underground hydrogen storage (UHS) essential successful economy. Options this are manmade caverns, salt domes/caverns, saline aquifers, depleted oil/gas fields, where large quantities of gaseous have been stored caverns many years. The key requirements intrinsic porous rock formation seasonal are: adequate capacity, ability contain H2, capability...

The Moab fault, a basin-scale normal fault that juxtaposes Jurassic eolian sandstone units against Upper and Cretaceous shale sandstone, is locally associated with extensive calcite lesser quartz cement. We mapped the distribution of fault-related diagenetic alteration products relative to structure identify sealing conductive segments for fluid flow relate fault–fluid-flow behavior internal architecture zone. Calcite cement occurs as vein breccia along slip surfaces discontinuous...
The Upper Cretaceous Mesaverde Group in the Piceance Basin, Colorado, is considered a continuous basin-centered gas accumulation which charge of low-permeability sandstone occurs under high pore-fluid pressure response to generation. High favors formation pervasive systems opening-mode fractures. This view contrasts with thatofothermodelsoflow-permeabilitygasreservoirsinwhich migrates by buoyant drive and accumulates conventional traps, fractures an incidental attribute these reservoirs. We...
Natural fractures form preferred pathways for basinal fluid flow and associated heat mass transport. In gas sandstone reservoirs with low matrix permeability, provide between organic-rich source reservoir layers during charge, pores, hydraulic fractures, the well bore production. While formation of natural has previously been generation pore-fluid pressure increase through a process referred to as fracturing, other driving mechanisms such stress changes by tectonic or exhumation processes...
Abstract An earthquake sequence that culminated in a M w 4.8 strike‐slip event near Timpson, east Texas, the largest reported to date region, had previously been attributed wastewater injection starting 17 months before onset of recorded seismic activity. To test if this can be injection, we conducted coupled poroelastic finite element simulations assess spatial and temporal evolution pore pressure stress field vicinity wells calculate Coulomb failure on seismogenic fault as function...
Abstract To investigate mechanisms of seismic fault reactivation in crystalline basement response to fluid injection overlying sedimentary reservoirs, we conducted three‐dimensional finite element simulations assess the effects direct pore pressure communication and indirect poroelastic stress transfer on change Coulomb failure favorably oriented faults varying permeability structure normal, strike‐slip, reverse faulting regimes. We demonstrate that effect transmitted along a hydraulically...
We report a structure that is characterized by localized increase in porosity or dilation within tabular band of on average 1–2 mm thickness porous, poorly consolidated sand. These bands formed predominantly opening‐mode and provide sharp contrast to planar fractures joints with two discrete surfaces consolidated, low brittle rock. Our observation bands, together previously recognized shear compaction complete the spectrum deformation modes along sand sandstone consistent recent theoretical...
Extensive calcite fault cement has resulted from leakage of Santa Barbara basin fluids and hydrocarbons into the Refugio-Carneros fault, a north-bounding structure to basin. Calcite cements are only found at end segments 24-km (15-mi)-long zone, which less than 150 m (490 ft) maximum normal offset. The is contemporaneous with movement, as evidenced by pervasive crystal twinning brecciation, well textures indicating repeated episodes rapid fluid flow cementation. Based on U-Th dates calcite,...
Tomographic images taken inside and outside a compaction band in field specimen of Aztec sandstone are analyzed by using numerical methods such as graph theory, level sets, hybrid lattice Boltzmann/finite element techniques.The results reveal approximately an order magnitude permeability reduction within the band.This is less than several orders measured from hydraulic experiments on bands formed laboratory about one inferences two-dimensional sandstone.Geometrical analysis concludes that...
Geological storage of CO2 (GCS), also referred to as carbon sequestration, is a critical component for decreasing anthropogenic atmospheric emissions. Stored will exist supercritical phase, most likely in deep, saline, sedimentary reservoirs. Research at the Center Frontiers Subsurface Energy Security (CFSES), Department Energy, Frontier Center, provides insights into process. The integration pore-scale experiments, molecular dynamics simulations, and study natural analogue sites has enabled...
Abstract Subcritical fracture behavior of shales under aqueous conditions is poorly characterized despite increased relevance to oil and gas resource development seal integrity in waste disposal subsurface carbon sequestration. We measured subcritical properties Woodford shale ambient air, dry CO 2 gas, deionized water by using the double‐torsion method. Compared tests presence reduces toughness 50%, index 77%, shear modulus 27% increases inelastic deformation. Comparison between test...
Abstract Recognition of the potential for subcritical fracture growth rocks is essential evaluation long‐term stability fluids trapped in geologic structures. In shales, may control migration hydrocarbons source rock and unconventional reservoirs sequestered CO 2 across top seals. Using double torsion method, we investigated mode‐I mechanical properties three shales different composition, namely, Woodford Shale, Mancos Marcellus under water‐saturated conditions, ambient air, dry gas...

Abstract. Recent investigations using the Monterey Bay Aquarium Research Institutes (MBARI) Remotely Operated Vehicles (ROVs) "Ventana" and "Tiburon" interpretation of MBARI's EM 300 30 kHz multibeam bathymetric data show that northern flank Santa Barbara Basin has experienced massive slope failures. Of particular concern is large (130 km2) Goleta landslide complex located off Coal Oil Point near town Goleta, measures 14.6-km long extending from a depth 90 m to nearly 574 deep 10.5 km wide....
