An Approach to Sustainable Hydrogen Generation From Stimulated Iron‐Rich Ultramafic Rock

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Iron‐rich rocks undergoing oxidation in the presence of water are promising sources of geologic hydrogen (H2). Yet, such reactions are often considered self‐limiting due to passivation and reduced permeability if volume expansion occurs. This study investigates hydrogen generation during a flow‐through experiment on fractured iron‐rich cores ...

A two-layer model–based coupled simulation study of multi-cluster hydraulic fracture propagation and proppant transport in shale

Natural Gas Industry B
Effective proppant placement in multi-cluster hydraulic fractures is crucial for shale gas fracturing; however, existing numerical methods face challenges in accurately coupling dynamic fracture propagation with suspended-load transport, bed erosion, and

Evolution of Friction and Permeability in a Propped Fracture under Shear

Geofluids, 2017
We explore the evolution of friction and permeability of a propped fracture under shear. We examine the effects of normal stress, proppant thickness, proppant size, and fracture wall texture on the frictional and transport response of proppant packs ...
