The World's Oil Giants Are Getting Crushed

And now, on Friday, shares of oil companies around the world are following suit.

Here are some of the biggest losers in premarket trade Friday:

• BP (BP), down 5%
• Royal Dutch Shell (RDS.A), down 5%
• Total (TOT), down 7%
• Statoil (STO), down 11%
• Exxon Mobil (XOM), down 3%
• ConocoPhillips (COP), down 4%
• Marathon Oil (MRO), down 4%
• Occidental Petroleum (OXY), down 3.5%
• Anadarko Petroleum (APC), down 6%
• Linn Energy (LINE), down 5%
• Whiting Petroleum (WLL), down 8%
• Oasis Petroleum (OAS), down 12%
• Kodiak Oil & Gas (KOG), down 10%

And this list goes on.

All areas of the oil space, from international behemoths like BP, to state-controlled companies like Statoil and Total, to US shale producers like Whiting and Kodiak, are getting hit.

On Thursday, while the US markets were closed for the Thanksgiving holiday, OPEC, the 12-member oil-exporting cartel, announced it would not cut production.

Many in the market had expected OPEC to announce a production cut to combat the global supply glut that has been blamed for some of the massive decline we've seen in the price of oil over the past several months. 

Instead, OPEC said it would maintain its current production level of 30 million barrels a day, which has been in place since December 2011. OPEC said it would meet again in June 2015.

On Thursday, West Texas Intermediate crude futures fell below $70 for the first time since June 2010. Thursday's one-day drop in WTI was also accompanied by a drop in Brent crude prices, and both benchmarks fell more than 6% in a 24-hour period. 

In early trade on Friday, crude prices were around $69.50.

On Thursday, Russian oil tycoon Leonid Fedun told Bloomberg that OPEC's decision not to cut production is part of an effort to flush out US shale producers, which have ramped up production significantly in the last few years.

Fedun said that the US shale boom is "on par" with the dot-com boom.

In a post on Business Insider on Thursday, former PIMCO CEO Mohamed El-Erian wrote that while the market's reaction Thursday indicated clear surprise at OPEC's decision, the market shouldn't have been shocked.

"OPEC has a history of opting for strategic rather than tactical decisions; and, this time around, it may have done so from a position of caution rather than overwhelming strength," El-Erian wrote.

And early Friday oil companies are feeling the pressure.
