“…The gas and source rock correlation shows that the natural gas has a very good correlation with the Jurassic source rocks, especially with the Middle and Lower Jurassic coal-bearing source rocks (Wang et al, 1998;Wang et al, 2008;Shen et al, 2010;Zhao, 2013). The Ro measurements of the Jurassic source rocks all over the Turpan-Hami Basin indicate that most of the source rocks in the Jurassic are immature (Cheng, 1994;Wang et al, 2008;Xu et al, 2008Xu et al, , 2009Lu et al, 2009;Zhao, 2013). Numerous previous studies have indicated that the presence of resin, suberinite, eight ring sulfur compounds and biodegradation in source rocks all contributed to the generation of abundant low maturity gas (Wang et al, 1998;Wang et al, 2008;Lu et al, 2009;Xu et al, 2009).…”
