DNO International Updates Operations

Oslo, 16 September 2013 -- DNO International ASA ("DNO International"), the Norwegian oil and gas company, announced today that it has commenced extensive testing of the Tawke-23 exploration well in the Kurdistan region of Iraq. The well is the second horizontal well drilled by the Company in the Tawke field and has encountered continuous oil shows within a 930 metre horizontal section in the main Cretaceous reservoir. The test program, expected to last up to three weeks, will focus on ten fracture zones with production potential.

The Company's first horizontal well in the field, Tawke-20, tested 8,000 barrels per day from each of ten producing intervals in the Cretaceous reservoir and is currently on stream at an average rate of 25,000 barrels per day.

Also currently drilling in Kurdistan are two other Tawke horizontal development wells, Tawke-21 and Tawke-22, and the highly deviated Benenan-4 well in the Erbil license designed to appraise the additional reserves encountered in the Benenan field by the Benenan-3 well earlier this year. Benenan-3 has been completed and temporary production facilities installed, pending government approval to commence sales.

The Bastora-2 well in the Erbil license has been completed and temporary production facilities are undergoing installation. The Bastora field development plan was previously approved and the Ministry of Natural Resources now has authorized sales from the field with first deliveries anticipated in October.

Elsewhere, drilling of the Saleh-8 well offshore the Emirate of Ras Al Khaimah has concluded and the rig released. The 5,205 metre well, including a 327 metre horizontal section, was drilled into the Thamama reservoir and delivered initial rates of 15 million cubic feet of natural gas and 1,000 barrels of condensate per day. The well subsequently exhibited a decline in flowing wellhead pressure and rates along with increasing water production. Saleh-8 will be tied into the existing infrastructure to enable production and pressure monitoring. In the interim, artificial lift studies will be undertaken on the partially depleted upper Wasia reservoir. An exploration well is also planned to be drilled to the east of the Saleh field by another operator in 2014. DNO International will be carried for a 16 percent interest on this well.

In Block 32, Republic of Yemen, the Salsala-1 exploration well has drilled through the primary Shugra formation target prospect. The well has reached 3,840 metres and is currently being logged and samples taken before resumption of drilling to a depth of 4,100 metres.

Based on current trends, DNO International expects third quarter production from its fields in Kurdistan, Oman and Yemen will reach record gross levels of around 85,000 barrels of oil equivalent per day (boepd), corresponding to an estimated Company Working Interest (CWI) production of 50,000 boepd. Gross production for full year 2012 was 67,238 boepd, corresponding to 38,354 boepd on a CWI basis.

The Company expects third quarter revenues will be around NOK 750 million.
