Polish state-run oil and gas producer PGNiG has reported an unsuccessful wildcat well at the Aasta Hansteen field in the Norwegian Sea.

PGNiG Upstream Norway said the 6608/1-1 S exploration well about 50 kilometres east of Aasta Hansteen came up dry, the Norwegian Petroleum Directorate (NPD) reported on Wednesday.

“The objective of the well was to prove petroleum in Pliocene reservoir rocks in the lower part of the Naust Formation,” the NPD said.

“The well did not encounter reservoir rocks at the presumed reservoir depth.”

According to the NPD, it was the first exploration well to be drilled in production licence 1017, which was awarded in 2018.

The well was drilled in 490 metres of water to a vertical depth 2400 metres below sea level, using the Deepsea Yantai drilling rig.

The well has been permanently plugged and abandoned.

PGNiG reported a healthy increase in its gas production for the first half of this year, helping to offset the financial hit taken from the halt in Russian pipeline gas supplies at the end of April.

The main source of the increase was the expansion of its assets in the Norwegian North Sea, where net gas production increased fourfold to more than 1.5 billion cubic metres.

Exploration and development revenues totalled about 17.6 billion zloty ($3.8 billion), a fivefold increase from the same period in 2021.
