The (incomplete) drilling history of ExxonMobil

ExxonMobil - The direct descendant of Standard Oil.

Ask someone in the general public about Standard Oil and Rockefeller and they will think his company found and produced oil.

Very few in the general public know that early on The Trust did very little upstream and was predominately a downstream refining, marketing and transportation business.

In 100 years, will we know Steve Jobs as the iPhone guy or the PC/Pixar guy?

As the center of the oil production universe spread from Pennsylvania, Standard had to venture into the upstream side of the business.

At their peak the combined entities that make up XOM 0.00%↑ would come to control ~20% of global oil production.
