When Ice Yields Fire - How USGS Explores the Cutting Edge of Gas Hydrates

When can ice yield fire? That’s the burning question at the heart of one of USGS’s longest-running research programs to date: the exploration of gas hydrates.

EarthWord - Gas Hydrate

Gas Hydrate Definition
Gas hydrate is a naturally-occurring, ice-like form of methane and water that is stable within a narrow range of pressure and temperature conditions. These conditions are mostly found in undersea sediments at water depths greater than 1000 to 1650 ft and in and beneath permafrost (permanently frozen ground) at high latitudes.

Exploring Gas Hydrates as a Future Energy Source

In the past decade, the development of the Barnett, Eagle Ford, Marcellus, and other shales has dominated the national consciousness regarding natural gas. But in Alaska, another form of natural gas has been the focus of research for decades—methane hydrate.

High-resolution seismic characterization of the gas and gas hydrate system at Green Canyon 955, Gulf of Mexico, USA

Outside Publication: Marine and Petroleum Geology
The Pliocene and Pleistocene sediments at lease block Green Canyon 955 (GC955) in the Gulf of Mexico include sand-rich strata with high saturations of gas hydrate; these gas hydrate accumulations and the associated geology have been characterized over the past decade using conventional industry three-dimensional...

Indian National Gas Hydrate Program Expedition 01 report

USGS Publication: Scientific Investigations Report 2012-5054
The Indian National Gas Hydrate Program Expedition 01 was designed to study the gas-hydrate occurrences off the Indian Peninsula and along the Andaman convergent margin with special emphasis on understanding the geologic and geochemical controls on the occurrence of gas hydrate in these two diverse settings.

Geological controls on the occurrence of gas hydrate from core, downhole log, and seismic data in the Shenhu area, South China Sea

Outside Publication: Marine Geology

Multi-channel seismic reflection data, well logs, and recovered sediment cores have been used in this study to characterize the geologic controls on the occurrence of gas hydrate in the Shenhu area of the South China Sea. The concept of the “gas hydrate petroleum system” has allowed for the systematic analysis of the impact of gas source, geologic controls...
