Petroleum Potential of the Sargelu and Naokelekan Formations in Northern Iraq

Petroleum Potential of the Middle–Late Jurassic Source Rocks (Sargelu and Naokelekan Formations) in the Kurdistan Region, Northern Iraq.

Authors

Evaluation of hydrocarbon potential reveals variability in source rock quality in Northern Iraq, suggesting significant regional differences.

This study aims to evaluate the petroleum generating potential of specific Jurassic formations in Northern Iraq.
Conducted geochemical analyses of organic matter from the Sargelu and Naokelekan Formations.
Performed Rock-Eval pyrolysis on outcrop samples collected from five sections.
Assessed total organic carbon (TOC) content, hydrocarbon generation potential, and kerogen types.
Sargelu and Naokelekan formations showed excellent source rock potential, especially in the Banik and Gara sections.
TOC values reached up to 20 wt% and S2 values exceeded 80 g HC/gr rock in high-potential areas.
Kerogen types identified were predominantly oil-prone Type II and mixed Type II/III with thermal maturity indicating oil generation.
