Almost half the rigs operating in Venezuela will shut down by Oct. 25 if the Trump administration doesn’t extend a 90-day waiver from its sanctions, according to data compiled from consultancy Caracas Capital Markets. That could further cripple the OPEC member’s production because the structures are needed to drill new wells crucial for even maintaining output, which is already near the lowest level since the 1940s.

“Almost half the rigs are being run by the Yanks, and if the window shuts down on this in two months, then that’s really going to hurt Venezuela unless the Russians and the Chinese come in,” said Russ Dallen, a Miami-based managing partner at Caracas Capital Markets.
