Cross-formational hydrocarbon accumulation of Cambrian sequences and its significance for natural gas exploration in eastern Sichuan Basin

Shiyou shiyan dizhi, 2023
It has not been clearly understood whether the hydrocarbon generated from the argillaceous sourcerocks of the Lower Cambrian Qiongzhusi Formation could upward pass through the regional cap rocks of the Lower-Middle Cambrian gypsum rocks and accumulate in

Paleo-environment of the first member of Niutitang Formation on the southern margin of Huangling anticline, western Hubei province: a case study of well ZD-1

Shiyou shiyan dizhi, 2022
The Lower Cambrian Niutitang Formation is one of the important targets for shale gas exploration in the western Hubei province. In view of the relatively weak research on the paleo-sedimentary environment of the 1st member of Niutitang Formation (Ꞓ1n1 ...

Lower Cambrian Organic-Rich Shales in Southern China: A Review of Gas-Bearing Property, Pore Structure, and Their Controlling Factors

Geofluids, 2022
The Lower Cambrian shales are widely developed in southern China, with greater thicknesses and higher TOC contents. Although the shale gas resource potential has been suggested to be huge, the shale gas exploration and development is not satisfactory. At

Source of hydrocarbons discovered from Cambrian sub-salt dolomite in Bachu uplift area, Tarim Basin

Shiyou shiyan dizhi, 2021
Exploration experiences have showed that the main source rocks of the Lower Cambrian have not been developed in the Bachu uplift; however, the well MB1 in this area had a good oil and gas showing in the Lower Cambrian.To clarify the hydrocarbon source of

Characteristics of Pore Structure and Gas Content of the Lower Paleozoic Shale from the Upper Yangtze Plate, South China

Energies, 2021
This study is predominantly about the differences in shale pore structure and the controlling factors of shale gas content between Lower Silurian and Lower Cambrian from the upper Yangtze plate, which are of great significance to the occurrence mechanism

Differences of Pore Features in Marine Shales between Lower Cambrian and Lower Silurian Formations of Upper Yangtze Area, South China

Energies, 2022
Lower Cambrian shale and lower Silurian shale are both typical of oil-prone kerogen and siliceous composition, but different in thermal maturities. Porosity differences were determined in marine shales between the two shales.
