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
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
Permeability of sediment cores from methane hydrate deposit in the Eastern Nankai Trough
Yoshihiro Konno,Jun Yoneda,Kosuke Egawa,Takuma Ito,Yusuke Jin,Masato Kida,Kiyofumi Suzuki,Tetsuya Fujii,Jiro Nagao +8 more
TL;DR: In this article, the authors measured the effective and absolute permeability of hydrate-bearing sandy sediment using natural sediment cores obtained from a methane hydrate reservoir in the Eastern Nankai Trough off the shore of Japan.

TL;DR: In this article, gas hydrate-bearing sediments from the eastern Nankai Trough, Japan, are characterized in terms of their lithology, interpreted processes and paleoenvironments of deposition, and various geometric parameters of their grain size distribution.
