IRVING, Texas -- September 27, 2017

Exxon Mobil Corporation (NYSE:XOM) today announced it has added 22,000 acres
to its Permian Basin portfolio since May through a series of acquisitions and
acreage trades. Located in the highly prolific, stacked oil pay zones of the
Delaware and Midland Basins, the new acreage adds to the company’s existing 6
billion barrels of oil equivalent Permian Basin resource base.

The recent transactions represent important additions to ExxonMobil’s
established core positions in the Delaware and Midland Basins. In February,
ExxonMobil acquired 250,000 acres in the Delaware Basin from companies owned
by the Bass family of Fort Worth. In the Midland Basin, the company has
doubled its core operated acreage to more than 130,000 acres through multiple
transactions over the last few years.

“We continue to build on our strong position in the Permian,” said Jack
Williams, ExxonMobil senior vice president. “Our leading presence in the
Permian, from equity production through to Gulf Coast refining capacity,
positions us well for the future.”

ExxonMobil is one of the most active operators in the Permian Basin, currently
operating 19 drilling rigs, 14 of which are drilling horizontal wells in the
core Midland Basin, where the company has added 200 wells since mid-2014. The
company also has four rigs drilling horizontal wells in the Delaware Basin of
New Mexico, where the company recently drilled its first 12,500-foot
horizontal lateral length well.
