Abstract

•Slow hydrate formation and accumulation process from dissolved gas in nature was simulated.•A dynamic hydrate evolution process exists: crystallization – migration – accumulation – recrystallization.•The final morphologies in pores are stiff frame supporting hydrate and patchy hydrate.•Hydrate saturation was inversed from resistivity and acoustic velocity for frame supporting hydrate.•Field of concentration, temperature and fluid velocity play key role on the discontinuity of hydrate distribution.
