Section: Crisp talk for data engineering track Technical level: Beginner


This talk describes the various machine learning algorithms used in the public SEG (Society of Exploration Geophysicist) challenge held in December 2016 to identify lithofacies based on well log measurements. Lithofacies are the different rock layers encountered during drilling, which are used to characterize the sub-surface. Correct classification of lithological facies helps in identifying target areas for hydrocarbon (oil and gas) extraction. The challenge concentrated on open-source tools, such as python and jupyter notebook, with collaborative code sharing via GitHub. The test data was provided by the SEG and the final submitted entry was one vs one multi class algorithm using Gradient boosting. The talk will explore the dataset, explain dataset conditioning, results on various algorithms used to train classifier, lessons learnt and future work.


The agenda will be as follows:-
1. Describing problem
2. Exploring dataset and conditioning
3. Algorithms used for best result
4. What did the winning team do
5. Lessons learnt and future work

    Interesting. Please share a draft slide deck detailing the content you will cover in this talk, and upload a two-min self-recorded video where you explain what the talk is about and the key takeaways for the audience. We need this information by May 23 to close the decision on your proposal.
