Japan Oil, Gas and Metals National Corporation ("JOGMEC", President: Hirobumi Kawano) participated with ConocoPhillips in carrying out a successful test of technology on the North Slope of Alaska that was able to safely extract a steady flow of natural gas from methane hydrates.
This test was the first ever field trial of a methane hydrate production methodology whereby CO<sub>2</sub> was exchanged in situ with the methane molecules within a methane hydrate structure.
This first proof-of-concept test commenced on February 15, 2012, and concluded on April 10. The team injected a mixture of CO<sub>2</sub> and nitrogen into the formation, and demonstrated that this mixture could promote the production of natural gas. The depressurization phase of the test extended for 30 days.
This test produced important results concerning both of gas exchange and depressurization behaviors.
JOGMEC will begin detailed data analysis to obtain knowledge useful for research activities in the fields such as CCS and unconventional gas. JOGMEC may utilize the test results for future research into the development of methane hydrates as well as enhancement recovery method complementing depressurization production.
