Abstract: Iraq is Located in the northeastern Arabian plate crossing five tectonic belts. The reservoir?forming conditions are very complex. After comprehensive analysis of its structure, sedimentation, strata lithology and litholodical facies as well as hydrocarbon distribution, this paper divided the Jurassic into such four plays as Najmah play, Sargelu?Naokelekan play, Mus play and Butmah play and analyzed the characteristics of them, according to the evaluations of the reservoirs, cap rocks and source rocks. Furthermore, this paper presents three favorable exploration areas in different levels. It is recognized that the southeastern Mesopotamia basin is the most potential area for Jurassic petroleum exploration, followed by the folded zone in the northeastern Iraq. But the cost and risk for their exploration and development are also very high
