Germany’s RWE has confirmed a gas find at the Zidane-1 wildcat well, drilled in production licene 435 about 15 kilometres north-west of the Heidrun field in the Norwegian sector of the North Sea.
The 6507/7-14S well, in the RWE-operated licence, hit a 150 metre column of gas in its primary target middle Jurassic reservoir rocks.
Preliminary estimates place the size of the find between 5 billion and 18 billion cubic metres of recoverable gas, the Norwegian Petroleum Directorate (NPD) said today.
A successful formation test has been performed with a maximum production rate of 1.2 million cubic metres of recoverable gas per day, the NPD added.
Further testing will be carried out to prove up reserves.
The secondary target failed to prove petroleum in the lower Jurassic reservoir rocks.
RWE and its partners will consider producing the discovery via existing infrastructure.
Scott Kerr, chief executive of licence partner Noreco, said: “We are very pleased with this discovery, which opens up more exciting exploration opportunities in the licence.”
Noreco said Zidane-1 boosts the prospectivity of the adjacent Zidane-2 prospect, which is very similar in terms of size and geology.
RWE operates production licence 435 with a 40% stake, on behalf of Edison (20%), Maersk (20%) and Noreco (20%).
The well was drilled by the Bredford Dolphin, which will now move onto RWE operated production licence 420 in the North Sea to drill wildcat well 35/9-6 S.
