Multimethod Prediction of Pore Pressure in the Deep Jurassic System of the Central Junggar Basin

Geofluids, Volume 2025, Issue 1, 2025.
Drilling has shown that there is significant overpressure throughout the Jurassic in the central Junggar Basin and that the maximum pressure coefficient exceeds 2.0. The pore pressure in the central Junggar Basin was jointly predicted by combining a number of methods, such as the Eaton, Bowers, and equilibrium depth methods based on logging data, with ...

Geochemical Constraints on the Generation of Coalbed Methane in the Weizhou Area, South‐Central Ningxia, NW China: Insights From Stable Isotopes and Organic Petrology

Geofluids, Volume 2025, Issue 1, 2025.
Amid growing global clean energy demand, coalbed methane (CBM) in the coal‐rich Weizhou area holds great development value. This study explores Weizhou CBM′s geochemical traits and genesis via analyzing gas compositions (Shanxi and Taiyuan Formations), stable isotopic distributions (δ13C1, δD, δ13CO2, and δ15N), and their burial depth variations ...

Tectonic Fracture Characterization and Stress Analysis in Complex Fault Block Formations: A Case Study in the Second Member of Dengying Formation in Central Sichuan

Geofluids, Volume 2025, Issue 1, 2025.
The Dengying Formation within Pengtan 1 well area in the Sichuan Basin is a vital gas reservoir for exploration and development. The reservoir is situated in a complex fault block structure characterized by multistage fault evolution, leading to a complicated distribution of tectonic fractures crucial for the accumulation and migration of oil and gas ...

Distributary channel type and high‐quality reservoirs in tight sandstone—A case study on the outcrops and reservoirs of Xujiahe formation in Western Sichuan Basin

Energy Science &Engineering, Volume 12, Issue 11, Page 5119-5144, November 2024.
Pattern of underwater distributary channel model and relationship between distributary channel type and high‐quality reservoir in outcrop profile. It is helpful in the evaluation of high quality reservoirs. Abstract The distributary channels in shallow‐water delta are well‐developed in tight sandstone.

Neogene‐Recent Reactivation of Pre‐Existing Faults in South‐Central Vietnam, With Implications for the Extrusion of Indochina

Tectonics, Volume 43, Issue 4, April 2024.
Abstract Vietnam contains complex faults coupled with a diffuse igneous province that has been active since the mid‐Miocene. However, existing fault maps demonstrate little consensus over the location of Neogene basalt flows and relative ages of mapped faults, which complicates interpretations of tectonic model for the evolution of Indochina.

Mechanisms of helium differential enrichment and helium‐nitrogen coupling: A case study from the Weiyuan and Anyue gas fields, Sichuan Basin, China

Geological Journal, Volume 59, Issue 1, Page 272-287, January 2024.
The uplift of the basement granite was crucial for the exsolution and enrichment of dissolved helium, and it was also the main reason for He–N2 coupling. The differential uplift that occurred in the Leshan–Longnvsi palaeo‐uplift during the Himalayan period further promoted the differential enrichment of He resources, thus also impacting the N2/He ratio
