Autor: Yoshiyuki SHIMIZU, Fumio KIYONO, Norio TEMMA

Publikováno v: Journal of MMIJ, Vol 133, Iss 10, Pp 241-249 (2017)

A numerical simulator is developed as a part of a Japanese National hydrate research program (MH21, funded by METI) to examine performance of methane gas production system from methane hydrate layer under deep seabed. The simulator solves mass and mo

Microscale Numerical Simulation of the Permeability Reduction due to Trapping of Suspended Fine Particles Within Sand Sediments

Autor: Norio Temma, Shinichiro Hirabayashi, Toru Sato, Jiro Nagao, Paul E. Brumby, Keisuke Mitsuhori, Hideo Narita

Publikováno v: Transport in Porous Media. 96:153-167

The reduction in permeability of sediments due to blockages caused by the trapping of suspended particles is a common concern for the extraction processes of oil or natural gas. In this study, the effect of trapped fine particles in sand sediments is
