North Sea crude, a European benchmark, closed the session at the Intercontinental Exchange trading 71 cents higher than the $69.42 it ended with on Thursday.
Today marked the second consecutive day of crude closing higher, allowing it to finish the week above $70, a level not seen since the end of July.
The recent upward trend is attributed to Ukrainian drone attacks on Russian energy infrastructure, such as the attack on the Afipski refinery in southwest Russia, which caused a facility fire and affected export flows.
