Statoil brings fifth fasttrack project onstream offshore Norway

Offshore staff

STAVANGER, Norway – Production has started from the Statoil-operated Stjerne oil and gas field in the Norwegian North Sea.

This is a tieback to the Oseberg South platform, 13 km (8 mi) to the northeast. The project came in on schedule, despite the delayed drilling start caused by a rig change. “We switched to Songa Delta and this meant that drilling and completion could be implemented faster than originally planned,” said Halfdan Knudsen, head of Statoil’s fasttrack development portfolio in Development & Production Norway (DPN). “Costs were NOK 500 million [$86 million] below the amount predicted at the time of the final investment decision.”

Stjerne was brought onstream within 39 months of discovery, but Statoil’s goal is to reduce average time of its fasttrack developments to 30 months, based on experience from the five it has so far completed.

For Stjerne, discovered in 2009, facilities comprise a four-slot seabed template. Eventually two wells will produce oil and gas, with a further two injecting water into the reservoir for pressure support.

Based on results from the single well currently in service, recoverable reserves have been upgraded to 49.2 MMboe.

In addition, the project should increase recovery from the Oseberg Omega North reservoir by 4.4 MMboe. According to the development, plan Total estimates output should reach 7,800 boe/d.
