Since 2014, the crude oil market has experienced declining oil prices around the globe. Speculations are that there has been over-supply in the market and lower demand than expected. In particular, the oil industry's oil industry in the United States took analysts and experts to surprise and the crude oil supply was not calculated in the forecasts. The production of this resource was preceded by the US, which gained extensive experience in the development of oil shale. Consistent developments in mass oil production coupled with the development of new technologies, which ensured a significant growth in the production of this hydrocarbon resource is believed to have significantly affected the global crude oil market. This article seeks to foster better understanding to the nexus of oil shale production and its impact on crude oil prices, as previous scientists have studied dating from the year 2002 to 2018 streamlined towards articles related to the impact of shale oil production on global crude oil prices. The study findings reveal that while some studies postulate that indeed US shale oil have negative impact on global crude oil prices, other studies also show that current lower crude oil prices could be attributed to several factors other than the mass production of US shale oil. Adversely other studies were indifferent with their findings and attributed the lower crude oil prices to both relatable factors such as the growth of US shale oil production, the slowdown of global oil demand, reduced cohesiveness of the OPEC cartel and production ramp-ups in other non-OPEC countries.
