==Slug flow in secondary, tertiary, and remigration==

Slug flow also dominates [[secondary migration|secondary]], [[Tertiary migration|tertiary]], and remigration. At each contact between a coarse pore network and a fine pore network, the mass of hydrocarbons accumulates until it reaches a buoyancy pressure great enough to overcome the capillary forces of the fine pore network. Relative [[permeability]] effects also aid migration. As hydrocarbons fill a pore network, the ability of a pore network to transport water decreases. This process builds pore pressure, helping push the hydrocarbons through the capillary restrictions.
