Investigation of Oil Trap in the Asmari Anticline (zagros, Iran)

Abstract

Asmari anticline (with 30 km length, 10 km width&1391 m height) is a NW-SE anticline in the North of Dezful Embayment sub-basin of Zagros. Anticlines of Zagros are signal for oil resources. Hence, Asmari anticline is analyzed, because it should be extended to trap. Items such as tectonic system after and before trap forming, detection of workable traps and finally resolving proper points for well drilling are investigated. We found that there is a relation between growth of Asmari anticline up Asmari fault, fracture spread and first oil migration in Asmari formation. As a result, with reference to Asmari thrust depth, Khami and Dehram groups could be suggested as a proper oil reservoir.
