I have the following idea for my MA thesis in economics, help me to find 4 resources for this topic 2 direct sources (like stats , reports, official statements) and 2 indirect sources (monographs, scientific papers..)

what does the data analytics says about the next market crash of oil and gas industry?

Analysis of data should be relative to the 2016 oil and gas market crash almost a decade after the 2008 the stock market crash.
