TUNISIA: Completion of Sabria N-2 Well Workover

Serinus Energy has announced that the workover operations on the Sabria N-2 well in Tunisia have been completed. Having successfully removed wellbore restrictions and recompleted the well, the Company has mobilised surface testing equipment to the well site to evaluate well production.

Upon completion of the testing program the Company will make a further announcement with the testing
results.

The workover was completed on time and within budget despite 3.5 days non-productive time caused
by high winds. The workover was performed with zero Lost Time Incidents. The Compagnie Tunisienne
de Forage crew Serinus says was performed well, and the CTF-004 rig experienced no material downtime.

Sabria is a large, conventional oilfield which the Company’s independent reservoir engineers have
estimated to have approximately 445 million barrels of oil equivalent hydrocarbons originally-in-place, of
which only 1.6 % has been produced to date.
