Saudi Arabia-Led Oil Cuts Run Into Gusher of Alternative Supplies

A burst of supply from a grab bag of smaller oil-producing countries threatens to undermine efforts by Saudi Arabia and its allies to keep prices high. 

Iran, Guyana, Norway, Kazakhstan, Brazil and Nigeria have pumped more oil since the fall, boosting the world’s supplies even as some of the biggest producers throttled back. Nigeria in particular has seen output bounce, with help from armed guards protecting barges in the vast creeks and waterways of the oil-rich Niger Delta.
