"We welcome shale oil as another additional supply and we don't really have a clash," OPEC Secretary General Abdallah el Badri told reporters in Vienna.
El Badri's comments came in response to claims of a possible confrontation between OPEC and the United States, a leading shale producer and the main catalyst behind falling global oil prices. Brent crude futures were trading at $76.52 Thursday morning, reaching a four-year low and marking a 30-percent drop since June.
An OPEC meeting was held in Vienna on Thursday, where the member countries gathered to discuss a possible curb of oil output amid the falling of oil prices on the global market. However, the group decided to maintain oil extraction at current levels.
