The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 229-246., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Technoeconomic evaluation of flared natural gas reduction and energy recovery using gas-to-wire scheme [PDF]

open access: yes, 2013
Most mature oil reservoirs or fields tend to perform below expectations, owing to high level of associated gas production. This creates a sub-optimal performance of the oil production surface facilities; increasing oil production specific operating ...

Production schedule optimization of gas wells in W shale gas reservoir under controlled pressure difference based on numerical simulation [PDF]

open access: yes, 2023
The complex fracture networks are often formed after large-scale hydraulic fracturing in shale gas reservoirs, and the shale gas production rates decrease quickly due to the stress sensitivity.

UK data and analysis for shale gas prospectivity [PDF]

open access: yes, 2010
Organic-rich shale contains significant amounts of gas held within fractures and micropores and adsorbed onto organic matter. In the USA shale gas extracted from regionally extensive units such as the Barnett Shale currently accounts for 6% of gas ...

The Analysis of Influence Factors on Electron Spin Resonance Signal Intensity in Dating of Quartz in Fault Lines

open access: yesYankuang ceshi, 2017
Electron Spin Resonance (ESR) is a dating technique using the accumulated irradiation energy in minerals under geological environments as the target. The quartz used for isotopic dating is widely distributed, and has an excellent time starting point to ...
