Geological conditions and enrichment patterns of helium reservoir in Yancheng Formation, Huangqiao area, Subei Basin

Shiyou shiyan dizhi
The helium (He) content in the natural gas of the Neogene Yancheng Formation in the Huangqiao area of Subei Basin ranges from 1.05% to 1.40%, which is generally higher than the industrial grade, indicating a crust and mantle composite type of helium ...

Origins of N ₂ in the Dongtai Depression of the Subei Basin [PDF]

Energy Exploration & Exploitation, 2010
Identification of N 2 origins can help to reduce exploration risks and to improve the understanding of gas generation and accumulation. N 2 from the mantle and organic matter in basins cannot be unraveled by using θ 15

Biological–physical oceanographic coupling influencing particulate organic matter in the South Yellow Sea

Frontiers in Marine Science, 2022
Using total suspended matter (TSM), particulate organic carbon (POC), and particulate nitrogen data, this study investigated the potential vertical POC flux and transport in the South Yellow Sea (SYS). The biogenic production and resuspension fraction (i.

Lacustrine Shale Diagenesis—A Case Study of the Second Member of the Funing Formation in the Subei Basin

Processes, 2023
Shale diagenesis differs from that of sandstone and carbonate rocks with regard to the type, evolution stage, and evolution mode. The quality of shale reservoirs is closely linked to the extent of diagenetic evolution. This study identifies the types and characteristics of shale diagenesis using thin sections and scanning electron microscopy (SEM ...

The Synthesis and Decomposition of Signals and Its Application in Subei Basin Exploration

Sains Malaysiana, 2017
Subei basin is the most promising onshore oil and gas bearing basin in South China. With the deepening of exploration, subtle hydrocarbon reservoirs have gradually become the major target of exploration. Seismic record often shows low signal to noise ratio (SNR), resulting that conventional seismic records have three shortcomings in the identification ...

Exploration strategies for complex fault block reservoirs in the Subei basin

Petroleum Science, 2007
The geological background of the Subei basin is that of small relief subsidence, low geothermal gradient, multi-sedimentary hiatuses, intense reconstruction of the basin, frequent magmatic activity, and a unique combination of source rock and reservoir. This geological background resulted in characteristics such as many small fault blocks, multiple oil-

Source identification and health risks of nitrate contamination in shallow groundwater: A case study in Subei Lake basin

Environmental Science and Pollution Research, 2022
Abstract Nitrate pollution in groundwater has become a global concern as it can affect the drinking water quality and human health. In this paper, an extensive hydrochemical investigation and health risk were performed in the Subei Lake basin where shallow groundwater is the main available drinking water resource for residents.

Characteristics and sedimentary environment of organic-rich shale in the second member of Paleogene Funing Formation, Subei Basin

Shiyou shiyan dizhi, 2020
Two sets of organic-rich shales are developed in the second member of Funing Formation (E1f2) in the Subei Basin, which are E1f2shale 1 and E1f2shale 2. They are widely distributed, with rich shows and favorable shale oil conditions.

Calculation method for CO2 geological storage capacity of fault-block traps in Subei Basin based on safety considerations [PDF]

Youqicang pingjia yu kaifa
To address the safety concerns associated with the CO2 geological storage process in fault-block traps of the Subei Basin, safety thresholds were systematically determined by integrating fault sealing capacity, caprock integrity, and wellbore stability ...
