Delta coal measures source rocks and terrigenous marine source rocks are developed in Enping Formation of Baiyun Sag, and their potential lithologic stratigraphic traps have self-generating, self-storing and self-capping reservoir-forming conditions, which have great exploration potential. Prediction is the main reservoir-forming combination of Baiyun Sag and the main direction of natural gas exploration in deep water area. Users of this data set should consider the geological uniqueness of the area, relying on the sedimentary characteristics informed by the Enping Formation for accurate prediction and exploration activities. Special attention should be given to the identification of authigenic conditions, self-storage, and self-sealing qualities of the potential traps. It is crucial to apply this data primarily for the assessment of exploration potential and to guide the strategic planning for natural gas extraction in the specified deep water area. Methodological approach in utilizing this data should be consistent with current geological exploratory practices and industry standards.
