Lacustrine organic-rich shales are widely developed within the Oligocene Biyang
Depression in the Nanxiang Basin in east China and across Southeast Asia. These shales …

Sodium carbonate evaporites can provide important paleoclimatic constraints and economic
resources but are relatively rare; most known examples are limited to the Cenozoic. The first …

This study examines problems that are related to large spatial variations in the physical
properties of fan-delta sandstone in the Baikouquan Formation on the western slope of the …

A total of 75 shale samples from the Biyang Depression were analyzed with Rock-Eval, total
organic carbon (TOC), organic maceral, and gas chromatography–mass spectrometry (GC …

The shallow-water braided deltas are hot topic in global sedimentology. In China, this
depositional environment forms an important reservoir and exploration target within the …

Salinized lacustrine organic-rich shale (SLORS) in the Paleogene has been considered as
one of the most important shale oil reservoirs in China. Although deposition of the …

The mechanisms leading to the formation of bedding-parallel calcite beef veins have been
widely debated, with discussions centered on timing or burial depth of vein generation …

The purpose of this study is to forecast the spatial distribution of diagenetic facies (DF) of
tight sandstone in the offshore sparse wells area. Analytical test data, rock physics …

Seismic sedimentology is an interdisciplinary field that integrates sedimentary geology and
geophysics to accurately characterize the spatial and temporal distributions of sedimentary …

Vertical natural fractures (NFs) are prevalent in low-permeability sandstone reservoirs.
Presently, the impact of NFs on the extension of hydraulic fractures (HFs) remains partially …
