Moody’s Investor Service is sounding the alarm with respect to oilfield services (OFS) companies and debt. In a publication for Moody’s clients issued earlier this week, analysts said OFS companies don’t have the means to pay back towering debt in the short term, and “limited options” when it comes to raising equity to improve liquidity. What it means is this: Companies like Schlumberger, Halliburton, and Baker Hughes a GE Company are heading for rough waters. However, the biggies, like the three we’ve mentioned, will probably be OK. But their smaller competitors, according to Moody’s, may not be OK.
