Trap pre-exploration ;Source rocks and terrigenous marine source rocks ; Natural gas exploration
Use advice for data set 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.
Technical purpose of product or process The data set describes the utilization of the Enping Formation within the Baiyun Sag, located in the Pearl River Mouth Basin, for the purpose of natural gas exploration. The geological formation exhibits favorable sedimentary conditions, including delta coal measures source rocks and terrigenous marine source rocks that contribute to the development of lithologic stratigraphic traps. These traps have self-generating, self-storing, and self-capping conditions essential for reservoir formation. This area is predicted to be the primary reservoir-forming zone in Baiyun Sag and represents a significant direction for deep water natural gas exploration initiatives, with potential for discovering large and medium-sized lithologic and stratigraphic traps.

Data selection and combination principles The sedimentary conditions of Enping Formation in Baiyun Sag form moderate sand-land ratio, which is beneficial to the development of lithologic stratigraphic traps. At present, more than 20 potential large and medium-sized lithologic stratigraphic traps have been searched, including six types, such as stratigraphic overlap, nearshore subaqueous fan, beach bar, low-level fan, delta front foregroove wedge sandstone body and updip pinchout sandstone body.
