Journal of Petroleum GeologyABSTRACT The Niutitang Formation shale is a key gas reservoir in the Upper Yangtze Plate, yet in the Qianxi block it exhibits anomalously low resistivity and severe gas depletion, posing exploration risks. Integrating petrology, geochemistry, petrophysics, gas content, and well logs, this study investigates the ...

Shales from the Lower Cambrian Niutitang Formation of Yangtze Platform have been widely investigated due to its shale gas potential. To better illustrate the pore structure and fractal characteristics of shale, a series of experiments were conducted on outcrop samples from the Lower Cambrian Niutitang Formation on Yangtze Platform, including X-ray ...

This paper studies the characteristics and controlling factors of nanopores in organic-rich shale in the Niutitang Formation. Six samples were collected from the bottom of the formation at the Jiumen Outcrop, Guizhou Province. Experiments were conducted to investigate the pore structures of these high-maturity shale samples.

The Niutitang Formation at the Huijunba syncline south of Hanzhong, China, has large shale gas resource potential. The development characteristics of shale nanoscale pores are key factors affecting the storage capacity of shale gas. To study the development mechanism, the shale pores in the area were systematically observed using scanning electron ...

The Terreneuvian Epoch (541–521 Ma)is also an important period for metallogenesis in South China, as was represented by the widespread occurrences of Ni-Mo polymetallic layers on the antecedent shallow platform margin and the V-enriched black shales in deeper slope-basin settings.

Controls on matrix permeability of shale samples from Longmaxi and Niutitang formations, China
Journal of Natural Gas Science and Engineering, 2016Abstract The Lower Silurian Longmaxi shale and the Lower Cambrian Niutitang shale are typical marine shales in China, promising for shale gas production, whereas the gas production from these two formations vary considerably because of the different flow properties determined by geology and lithology conditions.

Submarine hydrothermal/hot spring deposition of Early Cambrian Niutitang Formation in South China
Journal of Earth Science, 2010INTRODUCTION The relationship between life and environmental processes in critical geological periods is one of the significant geological issues and remains a major concern. Not only environment events led to life evolution, but also biological processes changed the environment and climate which in turn influenced sedimentation and ore forming.
