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. | [21] |
