The traditional group of "Supermajor" multinational oil and gas corporations—frequently called the Seven Sisters or modern oil supermajors—comprises ExxonMobil, Chevron, Shell, BP, TotalEnergies, ConocoPhillips, and Eni (or Saudi Aramco when measuring by sheer daily production volume). These massive vertically integrated enterprises handle everything from global crude exploration and extraction down to refining, petrochemical manufacturing, and worldwide fuel retail distribution.
