Logging evaluation of the engineering quality of the Paleogene Funing Formation oil shales in the Subei Basin

地质科技通报, 2023
Shale oil reservoirs, characterized by no productivity, are developed by horizontal drilling and volume fracturing, and it is very important to optimize shale fracable intervals based on engineering quality logging evaluation.

Logging evaluation methods of low-organic matter fault-block shale oil in the Subei Basin and their application [PDF]

Youqicang pingjia yu kaifa
The Subei Basin is characterized by a complex structure and well-developed faults. The shale in the second member of the Funing Formation has relatively low organic matter abundance, with a total organic carbon (TOC) generally below 1.5%.

Habitat and Haplotype-Specific Genetic Vulnerability Analysis Combined With a Multidimensional Scoring System Provides a New Insight for Conservation Prioritization of <i>Ephedra przewalskii</i>. [PDF]

Ecol Evol
This study assesses the vulnerability and adaptive capacity of Ephedra przewalskii populations using ensemble species distribution models and Climate‐Niche Factor Analysis, integrating climate and human activity data. It reveals that habitat fragmentation and shrinkage are exacerbated by climate change and anthropogenic activities, with varying genetic

CO2 storage capacity assessment of deep saline aquifers in the Subei Basin, East China [PDF]

International Journal of Greenhouse Gas Control, 2012
Abstract Geological storage of carbon dioxide (CO2) is one of the most critical technologies in reducing anthropogenic and fossil fuel emissions to the atmosphere. The most critical scientific problem has been the selection of storage site for long-term safety, as well as reliable and reasonable estimation of CO2 storage capacity. This paper analyzed

Microbial Community Composition and Function in Jiangsu Oil Reservoir Cores, China. [PDF]

Environ Microbiol Rep
Shale oil reservoirs meet the basic requirements for microbial growth. Microorganisms, crude oil and water are distributed within the pore spaces of the reservoir formation. In situ microorganisms utilise crude oil for growth and reproduction. ABSTRACT Shale oil reservoirs are typically characterised by elevated temperatures, confined spaces and ...
