Gas hydrate in nature

USGS Publication: Fact Sheet 2017-3080
Gas hydrate is a naturally occurring, ice-like substance that forms when water and gas combine under high pressure and at moderate temperatures. Methane is the most common gas present in gas hydrate, although other gases may also be included in hydrate structures, particularly in...

The discovery and character of Pleistocene calcrete uranium deposits in the Southern High Plains of west Texas, United States

USGS Publication: Scientific Investigations Report 2017-5134

This report describes the discovery and geology of two near-surface uranium deposits within calcareous lacustrine strata of Pleistocene age in west Texas, United States. Calcrete uranium deposits have not been previously reported in the United States. The west Texas uranium deposits share characteristics with some calcrete uranium deposits in...

EarthWord - Discovery

Discovery Definition: A “discovery” typically is an official announcement by a private company that shows an energy or mineral resource is present. For instance, in the oil and gas world, a discovery well is the first well that reveals the presence of a petroleum-bearing reservoir. Information on new oil field discoveries is compiled and reported by the EIA.

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...
