Coupling Relationship between Multistage Fluid Activity and Reservoir Abnormally High‐Porosity Zones in the Songtao–Baodao Region, Qiongdongnan Basin

Geofluids, Volume 2021, Issue 1, 2021., 2021
An abnormally high‐porosity zone (AHPZ) is beneficial for petroleum exploration, especially for the deep tight reservoirs in a petroliferous basin. Because of lacking effective research methods, it is hard to analyze the formation process of AHPZs in different geological periods.

Identification and Prediction of Allo‐Source Overpressure Caused by Vertical Transfer: Example from an HTHP Gas Reservoir in the Ledong Slope in the Yinggehai Basin

Geofluids, Volume 2021, Issue 1, 2021., 2021
The Yinggehai Basin is a typical high temperature and high pressure (HTHP) gas‐bearing basin. The pressure coefficient exceeds 2.2 in deeply‐buried Miocene reservoirs in the Ledong Slope, a nondiapir zone in the Yinggehai Basin. Determining the overpressure mechanisms and predicting the pore pressure are key issues for natural gas exploration and ...

Experiments on the Rock Electricity and Application Research considering the Influence of CO2 Content: A Case Study of the Dongfang 13 Gas Field

Lithosphere, 2022
A large number of CO2-bearing gas layers are distributed in the deep layers in the Huangliu and Meishan formations of the Dongfang 13 gas field. The presence of CH4, CO2, and formation water in CO2-bearing gas layers complicates the change of logging ...

Seismic Expression of Polygonal Faults and Its Impact on Fluid Flow Migration for Gas Hydrates Formation in Deep Water of the South China Sea

Journal of Geological Research, Volume 2011, Issue 1, 2011., 2011
Polygonal faults were identified from three‐dimensional (3D) seismic data in the middle‐late Miocene marine sequences of the South China Sea. Polygonal faults in the study area are normal faults with fault lengths ranging from 100 to 1500 m, fault spaces ranging from 40 to 800 m, and throws ranging from 10 to 40 m.
