What is it about?
The geochemical characteristics of the analyzed oil seep samples are similar, which is consistent with most of the crude oils in the northern and southern basins in Iraq, and were generated from the Middle Jurassic Sargelu Formation. The overall geochemical correlations and geological information confirm that the Abu-Jir Fault oil seeps in the western Iraq were sourced from the Middle Jurassic Sargelu Formation that reached an early maturity level of oil-generation window and that they migrated into the ground surface through the Abu-Jir major fault during the middle Miocene.

Why is it important?
The Abu-Jir oil seeps are generally heavy and degraded oils. The oil seeps were sourced from the middle Jurassic marine carbonate-rich source rock. A genetic relationship is found between oil seeps and the Middle Jurassic Sargelu Formation. The Abu-Jir oil seeps were migrated up to the ground surface through the Abo Jir major faults.
