StatoilHydro: Promising gas discovery in the Norwegian Sea
The well was drilled in production licence 218, which is located south-east of the Luva gas find and 280 kilometres west of Sandnessjøen in mid-Norway. StatoilHydro is the operator of the production licence. The purpose of the well was to confirm gas in reservoir rocks from the Late Cretaceous age in a prospect called Haklang.
A 127-metre long gas column was proven in a reservoir with good production qualities. Core drilling in the sandstone was carried out and fluid and pressure samples were taken.
The size of the discovery is estimated to be between 8 and 14 billion standard cubic metres (Sm3) of recoverable gas.
A joint development of Haklang and the nearby Luva and Snefrid South discoveries will be considered. Luva was confirmed by BP in 1997.
”We took over as operator and increased our interest in the licence to 75 per cent in 2006. This year we have drilled two exploration wells in the area – Snefrid South and Haklang."
“The total resource potential of these three finds is expected to be in the size of 40-60 billion cubic metres of recoverable gas,” says Mr Michelsen. “This well is an important step in order to prepare for a new deepwater development in the Norwegian Sea.”
The well is the third exploration well in production licence 218, which was awarded in the 15th licensing round in 1996.
The well was drilled to a depth of 3356 metres below sea level and was completed in the Nise formation in Late Cretaceous rock. The water depth is 1248 metres.
Well 6707/10-2S was drilled by Transocean Leader, which is now drilling sidetrack well 6707/10-2A with the aim of exploring a deeper prospect in the same production licence.
The partners in production licence 218 are: StatoilHydro ASA (operator) (75 per cent), ExxonMobil Exploration & Production Norway AS (15) and ConocoPhillips Skandinavia AS (10).
