Seismic evidence for shallow gas-escape features associated with a retreating gas hydrate zone offshore west Svalbard [PDF]

open access: yes, 2012
Active gas venting occurs on the uppermost continental slope off west Svalbard, close to and upslope from the present-day intersection of the base of methane hydrate stability (BMHS) with the seabed in about 400 m water depth in the inter-fan region ...

Gas-water interface migration characteristics of shallow gas reservoirs in Hangzhou Bay during advanced exhaust

open access: yesYantu gongcheng xuebao, 2022
It is of great significance to study the water-gas interface migration in gas reservoirs caused by gas release for advanced exhaust wells. Based on the theory of elastic water drive gas reservoirs, a theoretical model describing the variation of gas ...

Gas fields and large shallow seismogenic reverse faults are anticorrelated [PDF]

open access: yesScientific Reports, 2021
AbstractWe investigated the spatial relationships among 18 known seismogenic faults and 1651 wells drilled for gas exploitation in the main hydrocarbon province of northern-central Italy, a unique dataset worldwide. We adopted a GIS approach and a robust statistical technique, and found a significant anticorrelation between the location of productive ...

Study on the Micro-Mechanical Mechanism of Fine-Grained Marine Sediments Subjected to Shallow Gas Invasion

open access: yesJournal of Marine Science and Engineering, 2023
Marine sediment is an important channel for methane leakage from the earth interior to the atmosphere. The investigation of gas invasion in fine-grained marine sediments is of great theoretical and practical significance in marine science and engineering.

Gas slug ascent through changes in conduit diameter : Laboratory insights into a volcano-seismic source process in low-viscosity magmas. [PDF]

open access: yes, 2006
Seismic signals generated during the flow and degassing of low-viscosity magmas include long-period (LP) and very-long-period (VLP) events, whose sources are often attributed to dynamic fluid processes within the conduit.We present the results of ...
