Height Propagation Law and Controlling Strategies of Acid Fractures in Carbonate Gas Reservoirs With Bottom Water Layer Under Different Stress Profiles

open access: yesGeofluids, Volume 2025, Issue 1, 2025.
Acid fracturing is currently employed to develop the carbonate gas reservoir in the second section of the Dengying Formation at the Anyue Gas Field, Sichuan Basin. However, improper acid‐fracturing operational parameters pose a risk of fracture communication with the bottom water layer, leading to increased water production and a significant decline in

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

open access: yesGeofluids, 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 ...

Integrated stratigraphy and astrochronology of the Messinian GSSP at Oued Akrech (Atlantic Morocco) [PDF]

open access: yes, 2000
A much improved high-resolution integrated stratigraphy (calcareous plankton biostratigraphy, magnetostratigraphy, cyclostratigraphy) is presented for the classic section of Oued Akrech (Atlantic Morocco) straddling the Tortonian^Messinian boundary ...

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

open access: yesGeofluids, 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 ...

Genesis of Hydrothermal Geothermal System and Evaluation of Resources: A Case Study of Pingdingshan Coalfield, China

open access: yesGeofluids, Volume 2025, Issue 1, 2025.
As one of the clean renewable energy sources, geothermal energy has broad prospects, and correctly understanding its genetic mechanism and resource reserve is the basis for the efficient utilization of the geothermal resources. The characteristics of the ground temperature field in the Pingdingshan mining area are analyzed, and the influence of ...

Phytoplankton dynamics from the Cambrian Explosion to the onset of the Great Ordovician Biodiversification Event: a review of Cambrian acritarch diversity [PDF]

open access: yes, 2015
Most early Palaeozoic acritarchs are thought to represent a part of the marine phytoplankton and so constituted a significant element at the base of the marine trophic chain during the ‘Cambrian Explosion’ and the subsequent ‘Great Ordovician ...

Screening Assessment of the Impact of Structural and Sedimentary Geological Heterogeneities on the Performance of an Ultra‐Deep Carbonate Reservoir, North‐Central Tarim Basin, Northwest China

open access: yesJournal of GeoEnergy, Volume 2025, Issue 1, 2025.
Carbonate reservoirs host significant hydrocarbon, groundwater, geothermal and CO2‐ and H2‐storage resources. However, their complex depositional, tectonic and diagenetic histories make it challenging to efficiently characterize and predict their flow behavior. Here, we use a novel, rapid and efficient screening methodology that integrates experimental
