Shallow gas and gas hydrate occurrences on the northwest Greenland shelf margin [PDF]

Marine Geology, 2021
Industrial 3D seismic data are used to investigate the contemporary hydrocarbon distribution and historical fluid migration in Melville Bay offshore northwest Greenland. Gas-related amplitude anomalies and an extensive bottom simulating reflector (BSR) were mapped within the uppermost 1–2 km of stratigraphy to define the first inventory of shallow gas ...

A prediction model for hazard levels of shallow natural gas in tunnel based on K-means clustering and tabular prior-data fitted network

Results in Engineering
The hazard level of shallow natural gas in tunnels is jointly determined by the distance to oil and gas accumulation zones and the integrity of the storage-seal system.

GAS SIPS AND SHALLOW ACCUMULATIONS OF GAS ON THE SHELF OF TURKEY IN THE BLACK SEA [PDF]

Geology and Mineral Resources of World Ocean, 2021
It has been suggested that shelf and slope sediments of high deposition rate are methane sources, whereas the deep basin is methane sink. The methane production and migration in sediments may cause massive slope failures so methane is geologically important. Methane production is also economically important as methane seeps may indicate the presence at
