Hydrofracturing has been found in a numbs of sedimentary basins throug
hout the world, which pay an important role in the migration of hydroc
arbon and compaction of deposits in overpressured impermeable muddy ro
ck. The forming processes of hydrofracture in the basin evolution has
been simulated and the associated episodic compaction of deposits has
been evaluated. The modelling results indicate that episodic compactin
g process in impermeable rocks induced by hydrofracturing is an import
ant way of sediment compaction.
