Fluid Inclusion Stratigraphy and Multistage Hydrocarbon Evolution in the Risha Gas Field, Jordan

Geofluids, Volume 2026, Issue 1, 2026.
An integrated fluid inclusion stratigraphy (FIS) and petrographic analysis of the RH‐3 well in the Risha Gas Field, Jordan, reveals a highly compartmentalized vertical fluid column. The upper section (1200–1750 m) is dominated by wet‐gas to gas‐condensate fluids, transitioning to dry gas below 1850 m.

Multiscale Digital Core Technology for Analyzing the Genesis of Low‐Resistivity Oil Reservoirs in the Guantao Formation of Bohai Sea: Clay Mineral‐Induced Additional Conductivity Effect, Pore Structure Regulation Mechanism, and Quantitative Characterization

Geofluids, Volume 2026, Issue 1, 2026.
The genetic mechanism of low‐resistivity oil reservoirs in the Guantao Formation of the Bohai Sea is complex, and understanding the role of clay minerals and pore structures in forming low resistivity remains unclear. This study employed multiscale digital core technology to integrate multisource digital core data.

Mineral Carbonation for Carbon Sequestration: A Case for MCP and MICP

International Journal of Molecular Sciences
Mineral carbonation is a prominent method for carbon sequestration. Atmospheric carbon dioxide (CO2) is trapped as mineral carbonate precipitates, which are geochemically, geologically, and thermodynamically stable. Carbonate rocks can originate from biogenic or abiogenic origin, whereby the former refers to the breakdown of biofragments and the latter

Soil Improvement Using MICP and Biopolymers: A Review

IOP Conference Series: Materials Science and Engineering, 2017
Ground improvement techniques provide strong natural platforms for construction activities and save the need for designing more resistant structures which would have been necessary on weak ground. This paper discusses the biogeotechnical techniques for improving the resistance of unsaturated sand dunes against surficial erosion by natural processes of ...

Properties and Behavior of Sandy Soils by a New Interpretation of MICP

Materials
Research on MICP technology for ground improvement began in the early 2000s, and since then, it has been considered as innovative research. The field of applications is showing signs of expanding from sandy soil stabilization to remediation. However, the research has not always progressed, because it is extremely difficult to evaluate the ability ...
