2.2.1. PMA-to-Fracture Mapping

PMA-to-fracture mapping defines how fractures can be mapped to PMAs. F-tile has flexibility for this mapping but there are restrictions.

  • Not all PMAs map to all fractures
  • Not all fractures map to all PMAs
  • st_x16 maps to a set of four FHT PMAs, eight FGT PMAs, or 16 FGT PMAs, or four FHT PMAs and four FGT PMAs (mixed transceiver mode).
  • st_x8 maps to a set of four FHT PMAs, two FHT PMAs, eight FGT PMAs, or four FGT PMAs.
  • st_x4 maps to a set of four FHT PMAs, two FHT PMAs, one FHT PMA, four FGT PMAs, or two FGT PMAs.
  • st_x2 maps to a set of two PMAs or one PMA.
  • st_x1 maps to one PMA.
