Multidimensional Characterization of Formation Damage Mechanisms in Ancient Carbonate Reservoirs: Synergistic Effects of Inorganic‐Organic Interactions

Energy Science &Engineering, Volume 13, Issue 6, Page 2663-2671, June 2025.
ABSTRACT Formation clogging in carbonate gas reservoirs is a significant challenge in natural gas extraction, particularly due to the complex mineral composition and physicochemical characteristics of carbonate rocks, which make clogging phenomena even more complex. This study aims to delve into the formation mechanisms of formation plugs in carbonate

New Pattern of Uplift‐Depression of the Pre‐Cambrian Basement in the Sichuan Basin: Constraints From Multi‐Seismic Parameter Imaging

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract The structural configuration of the pre‐Cambrian basement in the Sichuan Basin, a highly promising region for hydrocarbon exploration, has been a subject of long‐standing debate. Here, we determined the fine‐scale three‐dimensional seismic models of the Sichuan Basin using 187,356 high‐quality P‐ and S‐wave travel time pairs recorded by 627 ...

Re-Os dating and oil-source correlation of the pyrobitumen in the Member 4, Dengying Formation of the Kangjiadong paleo-reservoir, northern margin of the Sichuan Basin

, 2022
There are pervasive pore-filling bitumen found in the dolomite reservoir of the Member 4 , Sinian Dengying Formation. However, the high maturity of the source rocks and bitumen and the complex geological tectonic activities make it difficult to restore ...

Towards an improved understanding of Ca–Mg carbonates with nonplanar surfaces: An experimental approach

Sedimentology, Volume 72, Issue 1, Page 100-131, January 2025.
ABSTRACT Saddle dolomite is a Ca–Mg carbonate characterized by curved crystal faces, curved cleavage and sweeping extinction under cross‐polarized light. Saddle dolomite and, generally, Ca–Mg carbonates with curved crystal faces, are often assigned to the burial (hydrothermal) realm and serve as proxy archives for hydrogeochemical processes in ...

Enrichment Mechanism of the Organic‐Rich Shale in Ediacaran Doushantuo Formation in Western Sichuan Basin, South China

Geofluids, Volume 2025, Issue 1, 2025.
The Ediacaran Doushantuo Formation in South China has been increasingly recognized as a significant potential source rock for hydrocarbon reservoirs, particularly in relation to the overlying Dengying Formation. This study conducts a comprehensive geochemical analysis of the organic‐rich shale from the Ebian‐Xianfeng section within the Sichuan Basin ...

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

Geofluids, 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

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 ...

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
