With the recently concluded nuclear deal between Iran and the P5+1 countries, oil prices have already started heading downward on sentiments that Iran's crude oil supply would further contribute to the already rising global supply glut. The economic crisis in Greece, OPEC's high production levels and China's market turmoil have created more pressure on oil prices, making a price rebound look highly unlikely in the near future. 

So, with the prices of both Brent and WTI moving towards $50 per barrel, the short to medium-term outlook for oil remains mostly bearish. This is bad news for the U.S. shale sector which is already dealing with rising debt and the ever-increasing risk of default. 

A recent Bloomberg report stated that U.S. driller's debts stood at $235 billion at the end of first quarter of 2015, which is quite worrying. Does this mean that the U.S. oil sector is likely to witness a lot more layoffs than we have seen so far? Surprisingly, a recent IHS study had revealed that the U.S. shale sector has been boosting job creation in addition to supporting around 1.7 million jobs in U.S. 

All this as the overall unemployment rate in U.S. has been declining since previous years. But with rising negative sentiment pertaining to oil prices, is U.S. the shale sector prepared to face one of its biggest tests yet? Will the industry be able to sustain another long period of low oil prices or will it once again resort to trimming its workforce? 

Low oil prices will most likely result in more job losses 

Since the oil price collapse of last year, we have seen how oil field services and drilling companies have slashed thousands of jobs in order to reduce costs and cut their operational spending. Some of the major oilfield companies like Schlumberger (SLB), Halliburton (HAL) and Weatherford (WFD) have already announced close to 20,000 layoffs as of February 2015.
