Pore Geometry and Its Influences on Methane Adsorption in Shale Gas Reservoirs: A Case Study of Longmaxi Shale in the Da’an Area, Chongqing, China

open access: yesJournal of GeoEnergy, Volume 2026, Issue 1, 2026.
Understanding pore structure and methane sorption (MS) in shale gas reservoirs is critical for accurately estimating gas‐in‐place and prospective natural gas resources. The Longmaxi Shale, a leading formation for deep shale gas development in China, faces challenges in its economic production due to its strong spatial heterogeneity, complex pore ...

Ensemble Kalman Filter Assimilation of ERT Data for Numerical Modeling of Seawater Intrusion in a Laboratory Experiment [PDF]

open access: yes, 2018
Seawater intrusion in coastal aquifers is a worldwide problem exacerbated by aquifer overexploitation and climate changes. To limit the deterioration of water quality caused by saline intrusion, research studies are needed to identify and assess the ...

A >70‐Myr‐Long Geomagnetic Field Reversal Hyperactivity Across the Ediacaran‐Cambrian Transition

open access: yesGeophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract The long‐term variation of the geomagnetic field is a key constraint for unraveling the geodynamo processes and the evolution of Earth's deep interior. However, the geomagnetic reversal pattern during the Ediacaran–Cambrian transition remains elusive. Here we present an integrated magneto‐ and cyclo‐stratigraphic study of a ∼1.8‐Myr‐long, late

Characterization of reactive transport by 3-D electrical resistivity tomography (ERT) under unsaturated conditions [PDF]

open access: yes, 2016
The leaching of nitrate from intensively used arable soil is of major concern in many countries. In this study, we show how time lapse electrical resistivity tomography (ERT) can be used to characterize spatially heterogeneous processes of ion production,

Review of artificial intelligence applications in geothermal energy extraction from hot dry rock

open access: yesDeep Underground Science and Engineering, Volume 4, Issue 4, Page 651-672, December 2025.
This paper systematically summarized the applications of artificial intelligence (AI) in hot dry rock (HDR) geothermal exploitation and discussed the limitations and opportunities. A novel intelligent HDR exploitation system was proposed to promote the development of HDR toward more efficiency, economy, and intelligence.

Gels for CO2 geo‐storage and conformance control: A systemic review of behavior and performance

open access: yesDeep Underground Science and Engineering, Volume 4, Issue 4, Page 612-637, December 2025.
This review provides a systemic evaluation of potential sealants used in CO2 subsurface storage practices. Critical analyses of how external factors like CO2, pH, brine salinity and hardness, rock mineralogy, pressure, temperature, and injectivity could affect the performance of different sealants are provided. Abstract Carbon capture and storage (CCS)
