Lithofacies palaeogeography as a guide to petroleum exploration

open access: yesJournal of Palaeogeography, 2013
Lithofacies palaeogeography as a guide to petroleum exploration is a very important topic. By using the following five exploration examples, this paper discusses the guide of lithofacies palaeogeography or of sedimentary facies to petroleum exploration ...

Tectonic evolution and controls on natural gas generation and accumulation in the Ordovician system of the Ordos Basin, North China

open access: yesEnergy Reports, 2021
The Ordovician system of the Ordos Basin is rich in oil and gas resources, but the tectonic evolution of Ordovician strata and controls on natural gas generation and accumulation are poorly understood.

Sequence stratigraphy of the Middle Jurassic Yan’an Formation (NE Ordos Basin, China), relationship with climate conditions and basin evolution, and coal maceral’s characteristics

open access: yesFrontiers in Earth Science, 2023
The Yan’an Formation of the Ordos Basin in North China is among the largest and most extensively studied Jurassic coal reservoirs in the world. The lacustrine Yan’an Formation was investigated near Dongsheng (Ordos Basin, China) in its sequence ...

A Genomic Catalog of Migratory Microbiomes from Wild Birds across China's Habitats

open access: yesAdvanced Science, EarlyView.
ABSTRACT Migratory birds play an important role in the spread of antimicrobial resistance (AMR); however, gaps in surveillance data from vital regions along migratory flyways across China limit the detection of emergent threats. Here, we assembled 340 metagenomes from 52 bird species covering 11 provincial administrative districts in China, presenting ...

Evolution of the Ordovician top boundary and its relationship to reservoirs' development, Ordos Basin

open access: yesPetroleum Exploration and Development, 2012
The control of structural evolution on the development of different types of Ordovician reservoirs in the Ordos Basin is discussed by studying the evolution of the Ordovician top boundary in geological times, and the mechanisms of formation and evolution

Geochemical characteristics and genesis of the Ordovician sub-salt natural gas in the Ordos Basin, China

open access: yesFrontiers in Earth Science, 2023
A significant amount of natural gas resources has been discovered in the Ordovician reservoirs under a thick layer of gypsum-salt strata as a result of ongoing research into deep natural gas in China’s Ordos Basin, however, the genetic type and source of

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

open access: yesDeep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Carbon isotopic signature of coal-derived methane emissions to the atmosphere: from coalification to alteration [PDF]

open access: yes, 2016
Currently, the atmospheric methane burden is rising rapidly, but the extent to which shifts in coal production contribute to this rise is not known.
