Overview

Analysis shows source rock characteristics and organic matter types in the Ora Formation, indicating petroleum potential.

Key Points

  • The analysis identifies three distinct palynofacies, indicating variations in organic matter content and type.
  • Pyrolysis results reveal type IV kerogen in outcrops, while the Jabal Kand-1 well contains types III and IV, suggesting different maturation levels.
  • The organic matter in the Ora Formation is characterized by moderate amounts and considerable maturity, especially in the Dershish section.
  • The findings imply that gas production from the formation is primarily derived from the reworked organic matter due to increased oxidation.
