Data from W-2 and W-4 well in the Lower Congo Basin

The data shows TOC and logging data form W-2 and W-4 well in the Lower Congo Basin.

Source rocks usually refer to the rocks buried in the ground that can generate oil and gas, which mainly include coal measures strata, mudstones, carbonate rocks and so on. Due to the limited and discontinuous distribution of samples in the Madingo Formation in the lower Congo Basin, it is difficult to identify and characterize in detail the source rocks in the whole study area with only limited TOC data. Previous studies have shown that logging data contain a variety of geochemical information on source rocks

According to logging data, only the TOC content of a single well can be predicted. Finally, the vertical distribution characteristics of TOC content in the study area can be predicted in order to provide data for further in-depth study on the evaluation of source rocks of Madingo formation in the Lower Congo Basin.
