Origin and spatial-temporal evolution of crude oil in coal-oil-gas symbiotic mines in Ordos Basin:Taking Lucun Mining Area as an example

open access: yesMeitan xuebao
A large number of mines in southern Ordos Basin have coal-oil-gas symbiosis, and the crude oil leaking from the top and bottom of the coal mining process has brought great security risks to the coal mining, so it is necessary to further identify the ...

Pore throat characteristics of tight sandstone of Yanchang Formation in eastern Gansu, Ordos Basin

open access: yesPetroleum Research, 2018
An important factor to evaluate reservoir quality is the pore-throat size. However, the strong heterogeneity makes it difficult to characterize the pore-throat distribution in tight reservoirs. The field emission scanning electron microscope (FESEM), high pressure mercury injection and rate-controlled mercury injection are used to investigate the pore ...

Aridity-driven decoupling of δ¹³C between pedogenic carbonate and soil organic matter [PDF]

open access: yes, 2020
Pedogenic carbonate is an invaluable archive for reconstructing continental paleoclimate and paleoecology. The δ¹³C of pedogenic carbonate (δ¹³C_c) has been widely used to document the rise and expansion of C₄ plants over the Cenozoic.
