Aspect of hydrocarbon migration

Description

Reference

Geological “Kitchen” for Hydrocarbons

The initial oil charge may have originated from the Pihama or Maui sub-basin

[2]

Temporal change

The petroleum flow through the fault zone and a transition to shallower strata during the Pleistocene, indicating evolving hydrocarbon flow patterns.

[16]

Thrasher’s Theory

Proposed hydrocarbon flow during Late Miocene and Early Pliocene

[13]

Vertical Migration

Describes the movement of hydrocarbons vertically along fault surfaces, potentially by passing the sealing capacity of the fault to prevent horizontal (cross-fault) flow.

[17]

Supporting Evidence for Regional Migration

Proposed charge directions align with regional up-dip migration patterns from the Pihama sub-basin.

[20]

Faults and Hydrocarbon Migration

Faults in geological formations can act as both conduits and barriers for the migration of hydrocarbons.
