Crude oil prices have soared in the past few weeks due to speculation that OPEC will meet the terms of its supply quota agreement with Russian Federation.
"The risk at this point is somewhat to the upside, particularly if we continue to see weak drilling numbers in the United States", Bart Melek, head of global commodity strategy at TD Securities in Toronto, said by telephone.
