A time series of produced shale gas samples from Lower Silurian Longmaxi Formation (Fm.)
were collected from six production wells during 3.5 years production period from the …

This paper focuses on the gas composition and carbon isotopic variation during gas
desorption from the shale in Ordovician Wufeng Formation-Silurian Longmaxi Formation …

Position-specific isotope compositions of light hydrocarbons are expected to provide
valuable information on their formation and migration-degradation processes. Here we …

Carbon isotope fractionation is a promising method to predict gas-in-place content and
evaluate the shale gas production stage. In this study, molecular simulations are conducted …

Faults are key components in defining fluid migration pathways and seals in sedimentary
basins. The sealing capacity of faults is closely related to the petrophysical and …

Methane isotope gas fractionation is an interesting topic during pressure depletion process.
In this study, molecular dynamics (MD) simulations were conducted to investigate transport …

Abstract The Longyearbyen CO 2 Lab of Svalbard, Norway was established to estimate the
potential for geological carbon sequestration at Spitsbergen. Several monitoring wells were …

Recent significant breakthroughs have been made of the Lower Silurian shale gas in the
Changning-Zhaotong blocks recently, the key exploration area of China. Through …
