# Source Rock Prediction Using Well Log and Seismic Data:
## 6 Conclusions  
1. The Lower-Cretaceous-Albian-stage source rocks in the Cote d'Ivoire Basin have a good hydrocarbon generation potential with average values of 2.63 wt.% and 4.06 mg/g. The organic matter abundance of the rocks is between 0.47 wt.% and 3.08 wt.% and the average hydrocarbon generation potential is 4.06 mg/g. On the whole, the rocks constitute good and high-quality source rocks. The organic matter type is mainly type II, and it is mainly in the low-mature to mature stages. The TOC is high in the depths of the lake basin and low at the edges, with the average value at the highest point being greater than 4 wt.% and the lowest about 1 wt.%, indicating a high overall abundance of organic matter.
2. The high-quality source rocks in the the Albian-stage of the Cote d'Ivoire Basin are characterized by a medium amplitude, a low frequency, and continuous, parallel-subparallel reflection. They have widely developed in a semi-deep-deep lake environments, and the lithology is mainly thick dark mudstone. The medium source rocks are characterized by a medium-weak amplitude, a medium-low frequency, and a continuous and subparallel reflection structures in the seismic profiles; they are mainly shallow lake sediments. The poor source rocks have the characteristics of foreprograde reflection and mainly develop in delta deposits.
3. The good-high-quality source rocks in the basin have mainly developed in the semi-deep-deep lake facies in the center of the eastern depression, with a maximum thickness of 1200 m, while the medium source rocks have developed in the shallow lake subfacies with a thickness of 150-300 m. In the east, there is a small source rock center with a maximum thickness of 900 m.
4. The Albian stage source rocks in the research area are of good overall quality; they are widely distributed and have significant thickness, exhibiting significant potential for development. The semi-deep to deep lake facies in the center of the lake basin represent a potential area for oil and gas reserve enhancement. As the area is located in the deep sea, it is essential to actively innovate deep sea exploration and development theories and technology, conduct comprehensive research around the Well R and the surrounding areas, and assist oil companies in achieving outstanding results in this region.
