Natural Gas Hydrates Recovered from the Umitaka Spur in the Joetsu Basin, Japan: Coexistence of Two Structure-I Hydrates with Distinctly Different Textures and Gas Compositions within a Massive Structure

Autor: Jun Yoneda, Masato Kida, Motoi Oshima, Norio Tenma, Yusuke Jin, Jiro Nagao, Yoshihiro Konno

Publikováno v: ACS Earth and Space Chemistry. 4:77-85

This study evaluated natural gas hydrates recovered from three different wells (J13R, J07RB, and J23R) at the Umitaka Spur in the Joetsu Basin, via Raman spectroscopy. The hydrates in two of the sa...

Thermal properties of highly saturated methane hydrate-bearing sediments recovered from the Krishna–Godavari Basin

Autor: Naoko Susuki, Michika Ohtake, Yoshitaka Yamamoto, Hiromitsu Morita, Michihiro Muraoka, Motoi Oshima

Publikováno v: Marine and Petroleum Geology. 108:321-331

We measured the thermal constants (including conductivity, specific heat, and thermal diffusivity) of methane hydrate (MH)–bearing sediment samples recovered in 2015 from the Krishna–Godavari Basin, in India. These samples were recovered through

Numerical analysis of gas production potential from a gas-hydrate reservoir at Site NGHP-02-16, the Krishna–Godavari Basin, offshore India–Feasibility of depressurization method for ultra-deepwater environment

Autor: Jiro Nagao, Akira Kato, Yusuke Jin, Masato Kida, Yoshihiro Konno, Norio Tenma, Jun Yoneda, Motoi Oshima

Publikováno v: Marine and Petroleum Geology. 108:731-740

Sandy gas-hydrate reservoirs are considered to be promising deposits for gas recovery, but the feasibility of the depressurization method in ultra-deepwater environments remains unclear because high pressure gradient induced by depressurization may i
