Approach to Hydrocarbon Accumulation in Piedmont of Zagros Foreland Basin, Iran

Abstract

Abstract: This paper presents period of hydrocarbon generation and trap structure formation in piedmont of Zagros foreland basin of Iran in view of the evolution history of source rocks and tectonic development history in this basin, and discusses its overall process of hydrocarbon accumulation from hydrocarbon-bearing characteristics in drilled structures. It is suggested that traps in the trailing edge of thrust group in southern Block-3 of Iran are dominated by oil accumulation, those in the middle of thrust group dominated by gas accumulation, while those in the peak of it are unfavorable for conservation and unsatisfactory in terms of exploration result and prospect. These recognitions can help to delineate the favorable places for oil-gas prospecting, and provide the significant pattern of hydrocarbon distribution in foreland basins.

Key words: Zagros, hydrocarbon accumulation pattern, petroleum system, thrust fault, foreland basin
