Key Findings of the World’s First Offshore Methane Hydrate Production Test off the Coast of Japan: Toward Future Commercial Production
Yoshihiro Konno,Tetsuya Fujii,Akihiko Sato,Koya Akamine,Motoyoshi Naiki,Yoshihiro Masuda,Koji Yamamoto,Jiro Nagao +7 more
TL;DR: In this paper, the authors report the first offshore methane hydrate production test conducted at the eastern Nankai Trough and show key findings toward future commercial production, which indicates that hydrate saturation reaches 80% and permeability in the presence of hydrate ranges from 0.01 to 10 mD.
Journal ArticleDOI
Phase diagram, latent heat, and specific heat of TBAB semiclathrate hydrate crystals
Hiroyuki Oyama,Wataru Shimada,Takao Ebinuma,Yasushi Kamata,Satoshi Takeya,Tsutomu Uchida,Jiro Nagao,Hideo Narita +7 more
TL;DR: In this article, the congruent melting points of two types of TBAB hydrates were determined from the phase diagram of semiclathrate hydrate nucleation under the condition of atmospheric pressure, latent and specific heats capacity of TBA-n-butyl ammonium bromide (TBAB) hydrate.
Journal ArticleDOI
Geological setting and characterization of a methane hydrate reservoir distributed at the first offshore production test site on the Daini-Atsumi Knoll in the eastern Nankai Trough, Japan
Tetsuya Fujii,Kiyofumi Suzuki,Tokujiro Takayama,Machiko Tamaki,Yuhei Komatsu,Yoshihiro Konno,Jun Yoneda,Koji Yamamoto,Jiro Nagao +8 more
TL;DR: In this article, the authors used geophysical logging and pressure coring at the first offshore production test site (AT1) located on the northwestern slope of the Daini-Atsumi Knoll in the eastern Nankai Trough to obtain basic information for methane hydrate (MH) reservoir characterization.
Journal ArticleDOI
Thermoelectric and transport properties of β-Ag2Se compounds
Marhoun Ferhat,Jiro Nagao +1 more
TL;DR: In this paper, the Hall coefficient, electrical resistivity, and Seebeck coefficient of n-type specimens of β-Ag2Se, the low temperature polymorph of silver selenide, were measured over the temperature range from 70 to 300 K.
Journal ArticleDOI
Mechanical properties of hydrate-bearing turbidite reservoir in the first gas production test site of the Eastern Nankai Trough
Jun Yoneda,Akira Masui,Yoshihiro Konno,Yusuke Jin,Kosuke Egawa,Masato Kida,Takuma Ito,Jiro Nagao,Norio Tenma +8 more
TL;DR: In this article, a triaxial compression test of gas-hydrate-bearing sandy sediments and clayey-silty sediments were conducted and the results indicated that the core samples are normally consolidated sediments.
