DNO Scores Bergknapp Upgrade

Oslo, 6 September 2021 - DNO ASA, the Norwegian oil and gas operator, today

announced that following the completion of an appraisal program on the 2020

Bergknapp discovery in the Norwegian Sea, the Company has upgraded its

recoverable resource estimate for this licence by 35 percent.

With further appraisal drilling and testing, the size of the previously

discovered recoverable resources in the Garn and Tilje formations is now

estimated by the operator to range between 40 to 84 million barrels of oil

equivalent (MMboe) of light oil.

Additionally, a sidetrack drilled to a vertical depth of 4,854 meters below sea

level encountered a 260-meter hydrocarbon column in the Åre formation not seen

in the original discovery well. The Åre reservoir is estimated by the operator

to hold 13 to 56 MMboe of recoverable resources. Investigation of collected

sidewall cores and fluid samples is ongoing to understand whether the

hydrocarbons present in the Åre formation primarily consist of light oil,

condensate or wet gas.

Wintershall Dea is operator of license PL836S with 40 percent and DNO Norge AS

and Spirit Energy each hold 30 percent. The Bergknapp discovery is located eight

kilometers west of the Maria Field (Wintershall Dea operated) in an area with

existing infrastructure. The partnership will now evaluate development options.

Meanwhile, DNO's 2021 Norwegian exploration and appraisal program continues with

the ongoing drilling of the Gomez prospect (DNO 65 percent and operator) and the

Black Vulture appraisal well (DNO 32 percent). The Mugnetind exploration well

(DNO 32 percent) will spud in September.

The Company has 74 licenses in Norway (of which 19 are operated) including eight

producing licenses with combined average daily production of 12,500 barrels of

oil equivalent in the first half of 2021, one license containing a discovery

undergoing development and five licenses with discoveries pending development

decisions.
