Characteristics of Micropore Structure and Its Influence on Shale Oil Occurrence: A Case Study From the Second Member of Funing Formation, Subei Basin

Journal of GeoEnergy, Volume 2025, Issue 1, 2025.
To clarify the micropore structure characteristics of shales in the second member of the Funing Formation, Subei Basin and their influence on shale oil occurrence, various tests were conducted, including low‐temperature nitrogen adsorption (LTNA), scanning electron microscopy (SEM), rock pyrolysis, total organic carbon (TOC), and X‐ray diffraction (XRD)

Huff-n-puff experiments of mixed CO2 and formation water for enhanced oil recovery of shale oil in the Subei Basin

Meitian dizhi yu kantan
ObjectiveIn the Subei Basin, the depletion-drive development of shale oil following reservoir volume fracturing faces challenges such as rapid production decline and low oil recovery. To address these issues, this study explored an experimental method of

Maternal Phylogeny and Genetic Structure of Wild Sheep/Argali (Bovidae, Ruminantia) Populations in China

Journal of Zoological Systematics and Evolutionary Research, Volume 2025, Issue 1, 2025.
Argali, also known as wild sheep (Ovis ammon), is a prominent alpine mammal found in Central Asia. It is of conservation concern globally and domestically in China. Our study aims to unveil the genetic diversity and phylogenetic relationships among argali populations in China using the mitochondrial cytochrome b (Cytb) and control region (CR) sequences.

Spatiotemporal Clustering of Large Earthquakes Along the Central‐Eastern Sections of the Altyn Tagh Fault, China

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 12, December 2024.
Abstract The understanding of the spatial‐temporal distribution of past earthquakes is essential to assess the event recurrence behavior and to estimate the size of potential earthquakes along active strike‐slip fault systems. However, the scarcity of paleoseismic data remains a major hurdle in this endeavor. This is the case of the longest strike‐slip

A Mid‐Crustal Channel of Positive Radial Anisotropy Beneath the Eastern South China Block From F‐J Multimodal Ambient Noise Tomography

Geophysical Research Letters, Volume 51, Issue 18, 28 September 2024.
Abstract We investigated the crustal radial anisotropy in the eastern South China Block (ESCB) with the F‐J multimodal ambient noise tomography. Well corresponding to widespread mid‐crustal low‐velocity zones in the VSV ${V}_{SV}$ model, a pronounced mid‐crustal channel of positive radial anisotropy is revealed.
