Submarine Fan Reservoirs

Until recently, submarine fans were considered unique to lowstand systems. Now, exploration geologists are looking at the potential of deep-water sands in highstand deposits.

Our answers:

  • Deltas can easily reach the shelf edge on a narrow shelf, such as in this example from the Mahakam Delta (Figure 1).
  • Even during relative sea-level rise, high sediment supply can deliver sand to slope canyons to feed highstand fans (Figure 2).

What do you think the sequence boundary would look like in each of these cases? Would there even be one?
