134.7m barrels per day? that sounds wrong...I thought total world consumption was only about 86m barrels per day...

One M is thousand, two MM is million. It comes from Latin “Mille” meaning “thousand”, so MM is a “thousand thousands” which equals one million.

Usually I see it capitalized. Most energy sources report uses M and MM. Reporters sometimes get lost in the units.

Addaxx Fact Sheet. You will see the use Mbbl/d for production (thousands barrels per day) and MMbbl for reserves (millions of barrels).
