  activities

IRVING, Texas–(BUSINESS WIRE)–ExxonMobil
has been named 2017 Explorer of the Year by the World Oil and Gas
Council in recognition of excellence and innovation in the global energy
industry.

“This award is recognition of ExxonMobil’s successful efforts to
strengthen our portfolio by accessing and discovering the highest
quality resources,” said Steve Greenlee, president of ExxonMobil
Exploration Company. “This recognition would not be possible without the
dedication of our employees and their daily commitment to safety and
operational excellence at every stage of exploration.”

During the year, ExxonMobil announced a number of discoveries,
acquisitions and other activities in various countries, including
Brazil, Cyprus, Equatorial Guinea, Guyana, Mauritania, Papua New Guinea
and Suriname.

Significant exploration activity took place offshore Guyana, where
ExxonMobil announced four discoveries in 2017 at Payara, Liza Deep,
Snoek, and Turbot. These four discoveries added to the earlier Liza
discovery, made in 2015.

Mike Cousins, executive vice president of ExxonMobil Exploration
Company, accepted the award on behalf of ExxonMobil at an award dinner
in London in December. He was accompanied by a number of company
representatives, including Kerry Moreland, Guyana Basin exploration
manager.

“Guyana has become an exciting exploration area where we have
consistently demonstrated our technical ability in deepwater exploration
and operations,” said Moreland. “We are planning for continued success
with our drilling program in 2018.”

Since receipt of the award in December 2017, ExxonMobil has announced a
sixth discovery offshore Guyana at the Ranger-1 exploration well.
