Yitong Graben in Jilin Province of China, hosts three basins, namely: Chaluhe, Luxiang and Moliqing basins. The Chaluhe basin, as the focal point of this study has five subdivisions, thus, Bo-Tai sag, Wanchang Structural high, Liangjia Structure high Xinanpu sag, and the Gudian slope, with a cumulative sedimentary rock thickness of about 6000 metres. The basin is supposed to be a potential hydrocarbon-producing basin with its better source rock distribution and more favorable maturation indicators than the adjacent Luxiang and Moliqing Basin. Determining whether the mudstone beds present in the Eocene Formations are matured enough to generate hydrocarbons, three (3) wells with Seismic Lines (clh02, clh05 and clh07) were used for the study. It is observed that the entire region from NW to SE in the source rocks is mature to produce oil and gas. At depths of about 2400 m and below show good maturity with vitrinite reflectance values averaging 1.02% Ro. The Eocene Shuangyang mudstone is the main petroleum source rock.
