Drilling of the Hamlet exploration well in the Gjøa licence (PL153) has started

(Trondheim, 28 February 2022) OKEA ASA (OSE: OKEA) announces that drilling
operations on the Neptune-operated Hamlet exploration well (35/9-16 S) have
commenced from the Deepsea Yantai rig. The well will be drilled 7 km north of
the Gjøa field and a discovery could be tied-back rapidly to the Gjøa platform.
The prospect lies in the Lower Cretaceous Agat Formation at a depth of
approximately 2600 m. OKEA holds a 12% working interest in the Gjøa licence
PL153.

''The Hamlet prospect is an exciting opportunity to discover new resources
within the Gjøa licence.'' says Andrew McCann, SVP Subsurface & Wells in OKEA.
"This is a further example of OKEA's strategy of identifying upside potential
for our producing assets where discoveries can be developed efficiently through
existing infrastructure'', Mr McCann added.

The drilling programme comprises a main well with an optional side-track
dependent on the outcome of the first bore. Further announcements will be made,
if applicable, when hydrocarbons are encountered, and/or on completion of
drilling operations.

Neptune Energy Norge AS is operator of PL153 with 30% working interest.  The
other licensees are Petoro AS (30% WI) and Wintershall Dea Norge AS (28% WI).
