Exploration potential analysis ; Marine source rock ; Organic geochemical analysis
Use advice for data set Users of this data set should consider the regional geological context when interpreting the organic geochemical analyses. The data is specifically applicable to the northwestern Sichuan region, and should not be extrapolated to other areas without further geospatial analysis. Users should account for the methodological approach used in the data collection, including the selection of outcrop sections and the techniques applied for determining organic matter characteristics. It is essential that users integrate this data with geological and geophysical data to derive robust conclusions on natural gas potential.
Technical purpose of product or process The geochemical analysis data set from the marine source rocks in northwestern Sichuan is intended for use by geological and geochemical researchers as well as the energy industry to evaluate the natural gas exploration potential. It includes assessments of organic matter abundance, type, and maturity within different geological formations, which can be used to identify areas with higher quality source rocks characterized by large thickness and wide distribution, and therefore indicate promising regions for future natural gas exploration and extraction activities.
