Exploration new opportunity captures

In 2018, we successfully added 54 new exploration blocks in 10 countries, totaling more than 17 million acres. ExxonMobil operates the majority of these newly captured licenses. Our exploration teams will test many of our recent captures over the next two years, with plans to nearly double exploration drilling activity. We are positioned to leverage industry-leading project development capabilities on future potential discoveries.


In 2018, ExxonMobil completed 19 divestment transactions, including the sale of our 50-percent operating interest in the WA-1-R block offshore Australia containing the Scarborough gas field; divestment of our interest in the Triton FPSO field cluster in the U.K. North Sea; the sale of our non-operated interest of a joint venture in Norway; and multiple divestments in the United States. Transactions in the United States included the sale of our interest in the Ram Powell field in the deepwater Gulf of Mexico and assets in the San Juan Basin, as well as divestment of ExxonMobil’s remaining interest in King Ranch.
