ExxonMobil has a variety of operations in the United States including oil and gas exploration, development and production.


ExxonMobil continues to actively pursue exploration activities in the U.S. Gulf of Mexico. We are one of the largest leaseholders in the deepwater Gulf of Mexico with interests in 339 deepwater blocks.

In 2013, ExxonMobil was awarded the right to explore seven blocks in up to 7,200 feet of water within the Central Gulf of Mexico.
