Brookian sequence well log correlation sections and occurrence of gas hydrates, north-central North Slope, Alaska
Kristen A. Lewis, Timothy S. Collett
2013, Scientific Investigations Report 2013-5050
Gas hydrates are naturally occurring crystalline, ice-like substances that consist of natural gas molecules trapped in a solid-water lattice. Because of the compact nature of their structure, hydrates can effectively store large volumes of gas and, consequently, have been identified as a potential unconventional energy source. First recognized to exist...
