Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

Journal of Petroleum Geology, Volume 49, Issue 2, Page 312-345, April 2026.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

A 500‐kyr Pluvial Interval Triggered Lacustrine Carbon Burial in Late Cretaceous East Asia

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The early Late Cretaceous hothouse was featured by intense storms and a prevailing monsoon climate, yet direct evidence for regional extreme precipitation events is rare. Here, we reconstruct local weathering and hydrological processes using magnesium and strontium isotopes (δ26Mg and 87Sr/86Sr) from lacustrine dolostones in the Upper ...

Critical Review on the Molecular Behavior of Surfactants at the Oil–Water Interface During Oil Displacement

Energy Science &Engineering, Volume 14, Issue 3, Page 1626-1662, March 2026.
This review systematically explores the molecular behavior of diverse surfactants (anionic, cationic, nonionic, amphoteric) at the oil–water interface through molecular dynamics simulations. It highlights their roles in reducing interfacial tension, altering interfacial structure, and enhancing oil recovery efficiency.

Global Comparison of Aqueous Geochemistry and Dissolved H2/CH4 in Continental Low Temperature Serpentinization–Influenced Environments

Hydrological Processes, Volume 40, Issue 3, March 2026.
Conceptual diagram of hydrological and geochemical processes within the Santa Elena Ophiolite, Costa Rica. It highlights watershed cross‐sections, soil genesis, hyperalkaline Type II waters (pH > 11.6) with calcite crust and trapped H2/CH4 gases, seepage into surface waters, storm‐impacted stream profiles, weathered vs.

DOLOMITE MINERAL EFFECTIVENESS ON THE SANDSTONE RESERVOIR PERMEABILITY

مجلة جامعة الزيتونة
The matrix rock formation acidization technique might be a regular mode to improve the sandstone rock permeability surrounding the wellbore. The dolomite rock (CaMg(CO3)2 can plug the pay zone around the wellbore and cause permeability reduction action ...

A Thermodynamic Framework for Turing‐Type Instabilities in Porous Media: Part II Applications

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Compaction bands, desiccation cracks, and melt segregation structures are geological patterns relying on the same fundamental manifestations of a universal Turing‐type instability mechanism, as predicted by the thermodynamically consistent reaction–cross‐diffusion framework developed in Part I (Regenauer‐Lieb et al., 2025, https://doi.org/10 ...

A reservoir rock wettability modifier for ultra-high temperature and high salinity environment

Energy Geoscience
During drilling process, the water phase in drilling fluids infiltrates rock fractures through capillary action. The surface wettability of dolomite is governed by multiple factors, resulting in an unstable wetting state. Studies have shown that altering

Broadband Dielectric Analysis of Clays: Impact of Cation Exchange Capacity, Water Content, and Porosity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Clay‐rich soils and sediments are key components of near‐surface systems, influencing water retention, ion exchange, and structural stability. Their complex dielectric response under moist conditions arises from surface–ion electrostatics and diffuse double layers that govern transport and retention processes. This study explores the broadband

Modeling the Deformation Response to Mt. Etna Sliding Flank

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The southeastern flank of Mt. Etna volcano slides into the Ionian Sea at rates of centimeters per year. While gravitational spreading and tectonic forces can cause volcanic flank collapse, their effects intrinsically trade off with magmatic forcing. There is still strong uncertainty regarding the processes underlying the sliding.
