Summary
Migration is like Einstein's watch. Observations concerning its operation can be made, but since opening the system is not permitted, only hypotheses about its operation, consistent with these operations, can be made. The movement of hydrocarbons in the deep and shallow subsurface is a complex balance of processes. We can draw conclusions based only on our observations. We may never know if these conclusions are correct for any given situation.
Martin D. Matthews, 1996Wide varieties of seabed features are formed as fluids migrate towards and emerge from the seabed; these include pockmarks and mud volcanoes. The nature and distribution of these features are dependent upon the supply of fluids, and the formations (rock and/or sediment) through which they migrate. To understand the formation of seabed fluid flow features and processes, various physical forces, including external triggers, must be considered.
