− | Continuous, separate-phase migration of hydrocarbons moves high volumes of hydrocarbons during primary, secondary, tertiary, and remigration. Several processes can occur during separate-phase migration: formation of small free hydrocarbon masses, slug flow, cosolution, and compositional changes due to phase changes. | + | Continuous, separate-phase migration of hydrocarbons moves high volumes of hydrocarbons during primary, secondary, [[Tertiary migration|tertiary]], and remigration.

− | Slug flow also dominates secondary, 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. | + | Slug flow also dominates secondary, [[Tertiary migration|tertiary]], and remigration.
