London-based BP has previously said it plans to cut its overall output by roughly 1 million barrels of oil equivalent (boepd) by the end of 2030 from its current 3.6 million boepd.
Of the five, Exxon is the largest producer, with daily output of 3.64 million boepd, but its production dropped 408,000 boepd between the first and second quarters. The five majors, which include Chevron Corp, Royal Dutch Shell and Total SA, also cut capital expenditures by a combined $25 billion between the quarters.
