Conclusions

  • Powerful Aptian to Cenomanian Type II source rock
  • Large influx of reservoir prone sands from PC Guyana shield
  • Efficient conduits from platform/slope canyons to slope fand and basin floor fans
  • Proven plays in Cretaceous basin floor and slope fan plays near 9 BBO found
  • Failures related to lack of charge in shallower sections. Efficient Paleogene seal
  • Future potential in Berbice canyon, Aptian rotated fault blocks and reef buildup plays
