Danish exploration and appraisal drilling in Licensing Rounds 1-6 outside the A. P. Møller Sole Concession area during the period 1984-2011 has been successful proving up oil and gas reserves in the order of 0.75-1 billion boe.
In recent years, increased focus has been placed on sandstones of Late and Middle Jurassic age. Additionally, younger parts of these strata may also contain interesting prospects. Several oil companies are currently evaluating discoveries in Paleogene reservoirs just above the chalk and even in sandstones of Neogene
The remaining oil and gas potential also outside of the established play types is believed to be significant, which has been proved by recent discoveries. In particular, the Jurassic turbidite sandstones are considered to hold a large reserve potential in the Danish Central Graben.
The use of improved geophysical methods is likely to unravel this oil and gas potential in the near future.
With an average E&A technical success rate of around 60 % for the Central Graben area, a commercial exploration success rate for the same area of around 25 % and an average finding cost around 3 USD(2011) per boe Denmark is still considered an attractive place to explore for oil and gas in many years to come.
