I think that falling oil prices have the following reasons. First, due to the COVID-19 epidemic, many countries restrict people from leaving their homes. Therefore, the world demand for gasoline dropped sharply. Second, the oil producing countries cannot close their oil production companies because the cost to close the companies and open the companiest after the epidemic is over is huge. So they chose the solution that produces oil as always. Therefore, the amount of oil in the storage is very large. So I think these are the main reasons for the significant drop in oil prices.
